# Drip

- Tool: Bubble
- Difficulty: Beginner
- Time required: 1–2 hours

## TL;DR

Connect Bubble to Drip using the API Connector with a Bearer token stored in a Private header. Drip's simple API token authentication (no OAuth, no expiry) makes setup fast. The primary use case for Bubble is recording custom e-commerce events — purchases, cart abandons, product views — that trigger Drip's automated email sequences. Store your numeric account_id as a Bubble App Constant because it appears in every endpoint URL.

## Drip as the E-Commerce Automation Layer for Your Bubble App

General-purpose email tools like Mailchimp and ConvertKit are built around lists and broadcasts. Drip is built around events — the specific actions an individual customer takes over time — and the automated email sequences those events should trigger. When someone views a product three times without buying, Drip can automatically send a targeted offer. When someone abandons a cart, Drip fires a recovery sequence. When a purchase is made, Drip switches the contact into a post-purchase nurture flow.

For a Bubble e-commerce app or marketplace, this event-based model is a natural fit. Bubble's workflow system lets you fire an API call at exactly the right moment — when the user clicks 'Add to Cart', when the Stripe payment confirms, when the user hasn't logged in for 30 days. Each of those moments maps directly to a Drip custom event, and each Drip event can be the trigger for a precisely targeted email sequence.

The integration is technically straightforward. Drip uses a non-expiring Bearer token (no OAuth complexity, no refresh logic), and Bubble's API Connector handles it cleanly with the token in a Private shared header. The account_id that appears in every Drip endpoint path is a minor but common setup detail — store it as a Bubble App Constant from the start to avoid problems if the account is ever transferred or migrated.

Drip's rate limit is 3,600 requests per hour (approximately one per second sustained). For a Bubble app that fires events on individual user actions, this is generous enough to handle significant traffic without caching. However, if your Bubble app polls for subscriber status on every page load for all active users, you should add a local cache layer in a 'Drip_Subscriber_Cache' Data Type and check freshness before making an API call.

## Before you start

- Active Drip account (free trial available; paid plans from $39/mo for 2,500 contacts)
- Drip API token (from Drip account menu → User Settings) and your Drip Account ID (visible in the URL when logged into Drip: drip.com/account/[ACCOUNT_ID]/dashboard)
- Bubble API Connector plugin installed (Plugins → Add plugins → search 'API Connector' → Install)
- For inbound Drip webhooks only: Bubble paid plan (Starter $32/mo+) — Backend Workflows required for webhook endpoints are not available on Free

## Step-by-step guide

### 1. Find Your Drip API Token and Account ID

Before opening Bubble, gather the two pieces of information you need from Drip.

For the API token: Log into your Drip account. Click your account name in the top-right corner to open the account dropdown, then select 'User Settings'. Scroll down to the section labeled 'API Token'. Copy the token — it is a long alphanumeric string. This token is tied to your Drip user account, not to a specific Drip workspace, so it works regardless of which workspace you are in.

For the Account ID: Look at your browser's URL bar while you are in the Drip dashboard. The URL format is: https://www.drip.com/account/[ACCOUNT_ID]/dashboard — the number between /account/ and /dashboard is your Account ID. It is a numeric value, typically 6-8 digits. Copy it.

Store both values somewhere secure — a password manager is appropriate — before moving to Bubble. The API token grants full access to your Drip account including the ability to modify subscriber records and trigger automations, so treat it like a password.

Note: The Account ID is a numeric value that appears in every single Drip API endpoint URL path. It is not the same as your Drip subdomain or account name. If you work across multiple Drip workspaces (e.g., for different brands or clients), each workspace has a different Account ID — make sure you have the one for the correct workspace.

**Expected result:** You have your Drip API token (a long alphanumeric string) and your numeric Account ID. Both are stored securely and ready for use in Bubble configuration.

### 2. Configure App Constants and Install the API Connector

Before building API Connector calls, save your Drip Account ID as a Bubble App Constant. The account_id appears in every Drip endpoint URL — if you hard-code it directly into each call and the account is ever transferred, migrated, or you need to switch environments, you would need to edit every single API call. An App Constant lets you update it in one place.

In Bubble, go to Settings (the gear icon in the left sidebar) → App Constants → Add a constant. Set Name to 'DRIP_ACCOUNT_ID' and Value to your numeric Account ID (e.g., '1234567'). Save.

Next, install the API Connector plugin. Go to Plugins → Add plugins → search for 'API Connector'. Install the one published by Bubble (the official plugin). After installation it appears in your Plugins list.

Click 'API Connector' in the Plugins tab to open its configuration panel. Click 'Add another API' to create a new API group. Name it 'Drip'.

Under the Drip API group's shared settings:
- Authentication: None (you will handle auth via a shared header)
- Under 'Shared Headers', click 'Add a new header':
  - Key: Authorization
  - Value: Bearer [your API token]
  - Check the 'Private' checkbox — this marks the header as server-side only, so your API token never reaches the browser

Do not put the API token in the Base URL or as a query parameter. Drip expects it as an Authorization header with the 'Bearer ' prefix (note the space after 'Bearer').

```
// Drip API Connector shared configuration
{
  "api_name": "Drip",
  "shared_headers": [
    {
      "key": "Authorization",
      "value": "Bearer YOUR_DRIP_API_TOKEN",
      "private": true
    },
    {
      "key": "Content-Type",
      "value": "application/json",
      "private": false
    }
  ]
}
```

**Expected result:** The Drip API group appears in the API Connector plugin with the Authorization shared header configured, Private checkbox checked, and no error messages. The DRIP_ACCOUNT_ID App Constant is saved in Settings.

### 3. Add and Initialize the Core API Calls

Within the Drip API group, add three calls that cover the most common integration needs: looking up a subscriber, creating or updating a subscriber, and recording a custom event.

Call 1 — Get Subscriber (GET):
- Method: GET
- URL: https://api.getdrip.com/v2/[DRIP_ACCOUNT_ID]/subscribers/[email]
  - Replace [DRIP_ACCOUNT_ID] with your App Constant value directly (you can type it as a static value in the URL, or use Bubble's ability to reference App Constants in API calls)
  - Replace [email] with a dynamic parameter — add a parameter named 'email' with a placeholder value
- Use as: Data
- For initialization: use a real subscriber email address from your Drip account, then click 'Initialize call'. Bubble will detect the response structure including fields like email, first_name, last_name, tags, status, and custom_fields.

Call 2 — Subscribe / Update Subscriber (POST):
- Method: POST
- URL: https://api.getdrip.com/v2/[DRIP_ACCOUNT_ID]/subscribers
- Body (JSON): {"subscribers": [{"email": "[email]", "first_name": "[first_name]", "tags": ["[tag]"]}]}
  - Add dynamic parameters for email, first_name, and tag (these will be supplied at runtime from Bubble Workflows)
- Use as: Action
- For initialization: use test values. Drip's subscriber endpoint silently upserts — calling it with an existing email updates the record, calling it with a new email creates it. Either is fine for initialization.

Call 3 — Record Custom Event (POST):
- Method: POST
- URL: https://api.getdrip.com/v2/[DRIP_ACCOUNT_ID]/events
- Body (JSON): {"events": [{"email": "[email]", "action": "[action_name]", "properties": {}}]}
- Use as: Action
- For initialization: use a test email and an action like 'Test Event'. After initialization, check your Drip dashboard → People → [test subscriber] → Activity to confirm the event was recorded.

```
// Call 1: GET subscriber by email
GET https://api.getdrip.com/v2/1234567/subscribers/<email_address>

// Successful response structure
{
  "subscribers": [
    {
      "id": "z1y2x3w4v5",
      "status": "active",
      "email": "customer@example.com",
      "first_name": "Jane",
      "last_name": "Smith",
      "address1": null,
      "city": null,
      "tags": ["customer", "vip"],
      "time_zone": "America/New_York",
      "utc_offset": -18000,
      "created_at": "2024-03-15T10:22:00Z",
      "href": "https://api.getdrip.com/v2/1234567/subscribers/z1y2x3w4v5"
    }
  ]
}

// Call 2: POST to create/update subscriber
POST https://api.getdrip.com/v2/1234567/subscribers
{
  "subscribers": [
    {
      "email": "<email_address>",
      "first_name": "<first_name>",
      "last_name": "<last_name>",
      "tags": ["<tag_name>"]
    }
  ]
}

// Call 3: POST custom event
POST https://api.getdrip.com/v2/1234567/events
{
  "events": [
    {
      "email": "<email_address>",
      "action": "<event_action_name>",
      "properties": {
        "order_id": "<order_id>",
        "total": "<order_total>"
      }
    }
  ]
}
```

**Expected result:** All three API calls appear in the Drip group within the API Connector plugin. The GET subscriber call initialized successfully and Bubble detected fields like email, status, and tags. The POST calls are marked as 'Action' type and ready to be used in Workflows.

### 4. Build E-Commerce Event Tracking Workflows

The highest-value use of Drip in a Bubble app is recording custom e-commerce events that trigger automated email sequences. This step wires those events to the right moments in your Bubble app's logic.

First, understand Drip's event naming convention: Drip's automation rules match event action strings exactly and case-sensitively. 'Placed an Order' and 'placed an order' are two completely different events in Drip. Before building these workflows, decide on your event naming standard and document it — changes later require updating both Bubble Workflows and Drip automation triggers simultaneously.

Workflow 1 — Purchase Event (trigger: payment confirmed):
In Bubble's Workflow editor, find the step in your checkout flow where payment is confirmed (typically immediately after a Stripe or PayPal API call returns success). Add a new workflow action:
1. Call API: Drip → Record Custom Event
2. email: Current User's email
3. action_name: 'Placed Order' (exact string — this must match your Drip automation rule trigger)
4. For the properties, add order_id and total as dynamic values from the order record

Workflow 2 — Cart Abandonment (trigger: Scheduled Workflow):
Cart abandonment detection requires a Scheduled Workflow. Create a 'Cart' Data Type in Bubble that records when a user adds items but has not converted. Run a Scheduled Workflow every few hours that searches for Cart records older than 2 hours with status 'active'. For each found cart, fire the Drip event 'Abandoned Cart' with the cart's item count and total value as properties.

Workflow 3 — Subscription / Signup Event:
In your user signup Workflow, after the user's account is created:
1. Call API: Drip → Subscribe / Update Subscriber (create the subscriber in Drip)
2. Then immediately: Call API: Drip → Record Custom Event with action 'Signed Up'
This ensures the subscriber exists in Drip before the event is recorded, preventing the event from being orphaned.

RapidDev's team has built e-commerce automation pipelines in Bubble with Drip for clients ranging from digital product stores to service marketplaces — if your setup involves complex event taxonomies or multi-product flows, a free scoping call is available at rapidevelopers.com/contact.

```
// Purchase event — full event body with order properties
{
  "events": [
    {
      "email": "customer@example.com",
      "action": "Placed Order",
      "properties": {
        "order_id": "ORD-2024-001",
        "total": 149.99,
        "currency": "USD",
        "item_count": 3,
        "product_names": "Premium Plan"
      }
    }
  ]
}

// Cart abandonment event
{
  "events": [
    {
      "email": "customer@example.com",
      "action": "Abandoned Cart",
      "properties": {
        "cart_id": "CART-789",
        "total": 89.99,
        "item_count": 2
      }
    }
  ]
}

// Win-back / inactivity event
{
  "events": [
    {
      "email": "customer@example.com",
      "action": "Became Inactive",
      "properties": {
        "days_inactive": 30,
        "last_login": "2024-05-15"
      }
    }
  ]
}
```

**Expected result:** When a test user completes a checkout in your Bubble app, the Drip activity log for that subscriber shows the 'Placed Order' event within seconds. In Drip → Automation, the campaign rule for 'Placed Order' shows 'enrolled 1 subscriber'. The event appears in the subscriber's activity timeline in Drip.

### 5. Wire Subscriber Management to Bubble Signup and Profile Workflows

Beyond event tracking, the subscribe and lookup calls are used at every user lifecycle touchpoint. This step connects those calls to the right Bubble Workflow triggers.

On User Signup:
In your Bubble signup Workflow (triggered by 'A User signs up' or after your custom signup form button action), add these steps in sequence:
1. Call API: Drip → Subscribe / Update Subscriber
   - email: Current User's email
   - first_name: Current User's first name (from signup form input)
   - tag: 'new-user' (helps Drip segment new signups from existing users)
2. Call API: Drip → Record Custom Event
   - email: Current User's email
   - action_name: 'Signed Up'

The subscribe call silently upserts — if the email already exists in Drip (e.g., someone who signed up for a marketing email before creating an account), the call updates the existing record rather than creating a duplicate. This is safe to call unconditionally.

On Profile Update:
If users can update their email address or name in your Bubble app, add a step to your profile-update Workflow that calls Drip → Subscribe / Update Subscriber with the updated fields. Note that if a user changes their email address, Drip treats this as a new subscriber — updating the email on an existing subscriber requires using the subscriber's Drip ID (retrieved via the GET subscriber call) combined with the PATCH /subscribers/[id] endpoint, which you can add as a fourth API Connector call if needed.

Subscriber Lookup for Marketing Opt-Out:
Before sending any marketing event to Drip (not transactional events), check whether the user has opted out. Call GET subscriber by email and check the 'status' field in the response. If status is 'unsubscribed', skip the Drip event call — Drip will reject the event for unsubscribed users and this saves a WU-consuming API call. Use a Bubble Conditional step: 'Only when result of step 1's subscribers first item's status is not unsubscribed'.

```
// Subscriber lookup response — check status field before sending marketing events
// status field possible values: active, unsubscribed, bounced, complained
{
  "subscribers": [
    {
      "status": "active",
      "email": "user@example.com",
      "tags": ["new-user", "trial"]
    }
  ]
}

// Subscribe call with multiple tags
{
  "subscribers": [
    {
      "email": "<email_address>",
      "first_name": "<first_name>",
      "last_name": "<last_name>",
      "tags": ["new-user", "trial", "bubble-app"]
    }
  ]
}

// Note: Drip returns HTTP 201 for subscriber create/update
// Response body is the created/updated subscriber object
```

**Expected result:** A new Bubble user signup creates a corresponding Drip subscriber within seconds. The subscriber appears in Drip → People with the 'new-user' tag and a 'Signed Up' event in their activity timeline. Existing email addresses are updated rather than duplicated.

### 6. Set Up Inbound Drip Webhooks (Optional — Paid Bubble Plan Required)

By default, this integration is outbound only — Bubble sends data to Drip. For some use cases, you also want Drip to notify Bubble when something changes: a subscriber unsubscribes, a tag is applied, an email is delivered, or a campaign email is clicked. This requires setting up a Bubble Backend Workflow as a webhook endpoint and registering it in Drip's webhook settings.

Important: Backend Workflows in Bubble are only available on paid plans (Starter at $32/mo or above). If you are on Bubble's Free plan, skip this step — the integration is fully functional without inbound webhooks.

In Bubble, go to Settings → API → enable 'This app exposes a Workflow API'. Then go to the Backend Workflows section and click 'New API workflow'. Name it 'Drip_Webhook_Handler'.
- Enable 'Detect request data' — this tells Bubble to accept the incoming webhook payload and expose its fields in subsequent workflow steps.
- Click 'Detect' and send a test webhook from Drip (instructions below) — Bubble will parse the payload and make the fields available as typed inputs.

Key fields in Drip webhook payloads:
- event: the type of event (e.g., 'subscriber.subscribed', 'subscriber.unsubscribed', 'subscriber.tag_added')
- subscriber.email: the subscriber's email address
- subscriber.status: their current status

In Drip, go to Settings → Webhooks → New Webhook. Enter your Bubble Backend Workflow URL — it follows the format: https://[your-app-name].bubbleapps.io/api/1.1/wf/drip_webhook_handler (note: use the production URL, not the version-test URL). Select the events you want to receive. Click Save.

In the Backend Workflow, add steps to handle the incoming data:
1. Condition: if event type is 'subscriber.unsubscribed' → search for Bubble User with matching email → update their email_opt_in field to 'No'
2. Condition: if event type is 'subscriber.tag_added' → log the tag to a 'Drip_Tag_Log' Data Type for analytics

Set up Privacy Rules for any Data Types that store subscriber status. Go to Data → Privacy → add rules restricting who can query the Drip_Tag_Log or subscriber status fields.

```
// Drip webhook payload — subscriber.unsubscribed event
{
  "event": "subscriber.unsubscribed",
  "data": {
    "account_id": 1234567,
    "subscriber": {
      "id": "z1y2x3w4v5",
      "status": "unsubscribed",
      "email": "customer@example.com",
      "first_name": "Jane",
      "tags": ["customer"],
      "unsubscribed_at": "2024-06-20T14:30:00Z"
    }
  }
}

// Bubble Backend Workflow endpoint URL format
// https://your-app-name.bubbleapps.io/api/1.1/wf/drip_webhook_handler
//
// IMPORTANT: This is the PRODUCTION endpoint URL.
// Do NOT use the development URL ending in /version-test/...
// Drip webhooks must point to the published version.

// Available Drip webhook event types:
// subscriber.subscribed
// subscriber.unsubscribed
// subscriber.tag_added
// subscriber.tag_removed
// email.delivered
// email.opened
// email.clicked
// email.bounced
```

**Expected result:** Drip's webhook settings page shows the Bubble URL with a green status indicator after a successful test. When a test subscriber unsubscribes in Drip, the corresponding Bubble User record's email_opt_in field updates to 'No' within seconds. The Logs tab shows a successful Backend Workflow execution.

## Best practices

- Document all custom event names in a single reference (an App Constant note, a Bubble internal page, or a shared team document) — Drip's event-action matching is case-sensitive and exact, so consistency between Bubble and Drip automation rule triggers is critical.
- Store the Drip account_id as a Bubble App Constant (DRIP_ACCOUNT_ID) rather than hard-coding it in each API call URL — this makes the integration portable if you need to switch Drip workspaces or accounts.
- Add a cache check before subscriber lookup calls — query a 'Drip_Subscriber_Cache' Data Type and only hit the Drip API if the cached data is older than one hour, to avoid approaching Drip's 3,600 req/hour limit on busy apps.
- Apply Bubble Privacy Rules to any Data Type that stores subscriber status or Drip activity data — email marketing opt-in status and unsubscribe events are privacy-sensitive and should not be queryable by all Bubble users.
- Consume WU efficiently by batching Drip subscriber creates when importing existing users — use Bubble's 'Schedule API Workflow on a list' to process users in batches rather than triggering one workflow per user simultaneously.
- Sequence your signup Workflow correctly: create the Drip subscriber BEFORE recording the 'Signed Up' event — if the event fires for an email that does not yet exist as a subscriber in Drip, the event may not associate correctly with the subscriber record.
- Test event automation end-to-end with a real Drip automation rule before considering it production-ready — confirm that the event fires in Bubble, appears in Drip's subscriber activity log, and successfully enrolls the test subscriber in the automation sequence.
- For inbound webhooks: always use the production Bubble Backend Workflow URL (not the version-test URL) in Drip's webhook settings. Drip cannot distinguish between your app's development and production environments — only the live published version should receive production webhook events.

## Use cases

### Purchase and Cart Abandonment Event Tracking

When a user completes a purchase in your Bubble app, post a 'Placed Order' event to Drip with the order details (order_id, total, items). If a user adds items to a cart but does not check out within a set time, a Bubble Scheduled Workflow detects the abandonment and posts an 'Abandoned Cart' event to Drip. These events trigger automated email sequences — post-purchase follow-ups for completed buyers, recovery offers for abandoners — without any manual Drip campaign management.

### User Signup and Onboarding Sequence Enrollment

When a new user signs up for your Bubble app, automatically create them as a Drip subscriber and tag them as a new user. Drip's onboarding email sequence begins immediately. As the user completes onboarding steps (connected a payment method, invited a team member, published their first listing), Bubble fires matching custom events that advance or modify the Drip sequence — switching from activation emails to engagement emails when the user is fully onboarded.

### Win-Back Campaign for Inactive Users

A Bubble Scheduled Workflow runs daily and queries users who have not logged in for 30 or 45 days. For each inactive user, Bubble fires a 'Became Inactive' event to Drip. Drip's win-back automation sends a sequence of re-engagement emails. If the user does return and log in, Bubble fires a 'Returned' event which exits the user from the win-back sequence in Drip.

## Troubleshooting

### API call returns 401 Unauthorized even though the API token appears correct

Cause: The most common cause is including 'Bearer ' (with a space) already in the token value itself, resulting in a double-prefix like 'Bearer Bearer [token]'. Another cause is copying whitespace before or after the token when pasting it into Bubble's API Connector.

Solution: In the API Connector, check the Authorization header value. It should read exactly: 'Bearer [your_token_here]' — with the word 'Bearer', one space, then the raw token string with no extra spaces or line breaks. Also verify the token is still valid in Drip → User Settings → API Token.

### Events are recorded in Drip but the automation rule never fires

Cause: Event action name mismatch between what Bubble sends and what the Drip automation rule expects. Drip matches event action strings case-sensitively and exactly. 'Placed Order', 'Placed an Order', and 'placed order' are three different events.

Solution: In Drip, go to the automation rule → open the trigger → check the exact event name configured. Then in your Bubble Workflow → API Connector call → verify the action_name parameter value matches character-for-character. Fix the mismatch in either Bubble or Drip (but not both inconsistently). Consider using lowercase with hyphens for all event names to reduce case confusion.

### 'There was an issue setting up your call' when initializing the custom event POST in the API Connector

Cause: Drip's event endpoint returns HTTP 204 No Content on success — an empty response body. Bubble's API Connector initialization expects a JSON response body to detect field types, and an empty 204 response causes the 'issue setting up' error.

Solution: This is expected Drip API behavior — the event endpoint intentionally returns no body. Click 'Initialize call' and accept the empty response. Add all needed parameters (email, action, properties) manually in the Params/Body section rather than relying on Bubble's auto-detection. Set 'Use as: Action' and proceed — the call will work correctly in Workflows even without detected response fields.

### Rate limit errors (429 Too Many Requests) during high-traffic periods

Cause: Drip's rate limit is 3,600 requests per hour. If your Bubble app calls Drip on every page load or every user action for a large number of concurrent users, this limit can be reached. Common culprit: checking subscriber status on every dashboard page load without caching.

Solution: Add a 'Drip_Subscriber_Cache' Data Type with fields: email (text), status (text), tags (text list), last_checked (date). In any Workflow that checks subscriber status, first search the cache — if last_checked is within the past hour, use the cached value. Only call Drip API if the cache is stale or missing. This reduces Drip API calls dramatically without meaningfully impacting data freshness for email marketing purposes.

### Backend Workflow webhook endpoint returns 404 when Drip tries to deliver events

Cause: The Backend Workflow URL is incorrect — either using the development URL (/version-test/wf/...) instead of the production URL, the Backend Workflow name has a space or special character that doesn't match the URL slug, or the Workflow API is not enabled in Bubble Settings → API.

Solution: In Bubble Settings → API, verify 'This app exposes a Workflow API' is enabled. Then go to the Backend Workflow, click 'Detect', and copy the exact URL shown — do not construct it manually. Verify the URL uses your production app domain (e.g., appname.bubbleapps.io), not the version-test URL. Update the webhook URL in Drip's settings and send a test event.

## Frequently asked questions

### Does Drip's API token expire?

No. Drip uses a simple non-expiring API token — unlike tools requiring OAuth flows or 1-hour access tokens (like Marketo or Reddit Ads), Drip's token remains valid indefinitely until you manually regenerate it in your Drip User Settings. This makes it maintenance-free: configure it in Bubble's API Connector once and it will continue working without any token refresh logic.

### Where do I find my Drip Account ID?

Your Account ID is visible in your browser's URL bar when logged into Drip. The URL format is: https://www.drip.com/account/[ACCOUNT_ID]/dashboard — the number between '/account/' and '/dashboard' is your Account ID. It is a numeric value, typically 6-8 digits. It is NOT the same as your subdomain or account name. If you manage multiple Drip workspaces, each workspace has its own Account ID.

### Can I use Drip on Bubble's free plan?

Yes, for outbound integration (Bubble sends data to Drip). The API Connector, subscriber creation, and custom event recording all work on Bubble's Free plan. The only feature that requires a paid Bubble plan is inbound webhooks — receiving Drip events (unsubscribes, tag changes, email clicks) in a Bubble Backend Workflow. If you only need to sync subscribers and fire events to Drip, the Free plan is sufficient.

### Drip's event automation is not triggering even though the event appears in the subscriber's activity. Why?

The most common cause is an event action name mismatch. Drip matches event action strings case-sensitively and exactly — 'Placed Order' and 'Placed an Order' are different events. Open the Drip automation rule, check the exact trigger event name, and verify your Bubble API Connector call sends the identical string. Another cause: the subscriber may have already been through the automation and Drip's rule is set to 'enroll once only' — check the automation's enrollment settings.

### How do I handle the unsubscribe sync back from Drip to Bubble?

When a subscriber unsubscribes in Drip (via email link or Drip admin), Drip can notify your Bubble app via a webhook. Set up a Bubble Backend Workflow as a webhook endpoint (requires a paid Bubble plan), register it in Drip Settings → Webhooks with the 'subscriber.unsubscribed' event type, and configure the Backend Workflow to update the matching Bubble User record's email_opt_in field. This keeps your Bubble user database in sync with Drip's opt-out records.

### How is Drip different from Klaviyo or Mailchimp for a Bubble e-commerce app?

Drip's differentiator is its custom event model with revenue attribution — it is specifically designed for e-commerce operators who want to trigger emails based on purchase behavior, cart value, and product interest. Mailchimp is stronger for general broadcast emails and newsletters. Klaviyo offers similar event-based automation but is more deeply integrated with Shopify; if your Bubble app is a custom storefront rather than a Shopify store, Drip is often the better fit.
