# How to Integrate Retool with AWeber

- Tool: Retool
- Difficulty: Beginner
- Time required: 20 minutes
- Last updated: April 2026

## TL;DR

Connect Retool to AWeber by creating a REST API Resource with AWeber's API base URL and OAuth 2.0 access token authentication. Use AWeber's API to build a subscriber management dashboard — manage lists, add and remove subscribers, view campaign open and click rates, track list growth, and monitor unsubscribes from a centralized Retool panel for your email marketing operations.

## Build an AWeber Subscriber Management and List Health Dashboard in Retool

AWeber is a dependable email marketing platform used by hundreds of thousands of small businesses and independent creators. Its built-in reporting interface covers the essentials, but teams that need to cross-reference email metrics with business data, perform bulk subscriber operations, or build automation around list health events find themselves limited by AWeber's standard UI. Retool bridges this gap by providing a configurable operations panel where your team can manage AWeber subscribers alongside internal business data.

With a Retool-AWeber integration, your marketing and operations teams can view all subscriber lists with real-time subscriber counts and growth trends; search for individual subscribers by email to check their subscription status and tag assignments; view campaign open rates, click rates, and unsubscribe counts for each broadcast; add new subscribers from internal forms without needing AWeber UI access; and identify subscribers who have unsubscribed or bounced to clean up your internal CRM records.

AWeber's API uses OAuth 2.0 for authentication. The integration requires an initial OAuth authorization step to obtain an access token and refresh token, after which Retool can make API calls on behalf of your AWeber account. AWeber's v1.0 REST API provides access to accounts, lists, subscribers, messages, and stats endpoints, covering all the core subscriber management operations your team needs.

## Before you start

- An AWeber account with API access — create an AWeber Developer App at https://labs.aweber.com to obtain OAuth credentials (client_id and client_secret)
- An OAuth 2.0 access token obtained via AWeber's authorization flow — AWeber provides a convenient self-authorization tool in their developer portal for single-account access
- Your AWeber account ID (numeric ID visible in the AWeber UI URL, e.g., /accounts/12345678/)
- A Retool account with permission to create Resources
- Familiarity with Retool's query editor and Table component

## Step-by-step guide

### 1. Obtain AWeber OAuth credentials and access token

Before configuring Retool, you need to set up an AWeber Developer App and obtain an OAuth access token. Navigate to https://labs.aweber.com and sign in with your AWeber account credentials. Click 'My Apps' and create a new application. Give it a name (e.g., 'Retool Integration'), enter a callback URL (for single-account use, any URL works as a placeholder), and save the app. You will receive a Client ID and Client Secret — copy both.

For a single AWeber account integration (the most common use case), AWeber provides a self-authorization shortcut. In your developer app page, click 'Get Access Token'. This opens a simplified OAuth flow where you grant the app access to your own account and immediately receive an access_token and refresh_token without implementing the full OAuth redirect flow.

Copy the access_token and refresh_token. AWeber's access tokens expire after one hour and must be refreshed using the refresh token. For a production Retool integration, store both tokens as configuration variables: Settings → Configuration Variables → create AWEBER_ACCESS_TOKEN and AWEBER_REFRESH_TOKEN, mark both as Secret.

Also find your AWeber Account ID — it is the numeric ID in your AWeber account URL (e.g., https://app.aweber.com/accounts/1234567/) or visible in AWeber's API when you call the /accounts endpoint. Store it as a configuration variable named AWEBER_ACCOUNT_ID.

For automated token refresh, plan to build a Retool Workflow that POSTs to AWeber's token endpoint with the refresh token before the access token expires.

**Expected result:** You have an AWeber Developer App with Client ID and Client Secret, an active access token stored in the AWEBER_ACCESS_TOKEN configuration variable, a refresh token in AWEBER_REFRESH_TOKEN, and your numeric account ID in AWEBER_ACCOUNT_ID. All three are marked as Secret.

### 2. Create an AWeber REST API Resource in Retool

Navigate to the Resources tab in Retool and click Add Resource. Select REST API from the resource type list. Name the resource 'AWeber API'.

In the Base URL field, enter https://api.aweber.com/1.0. This is AWeber's current REST API base URL. All endpoint paths in your queries will append to this base.

In the Authentication section, select Bearer Token from the dropdown. In the Token field, reference the configuration variable: {{ retoolContext.configVars.AWEBER_ACCESS_TOKEN }}. This keeps the access token out of the resource configuration UI and allows you to update it (when refreshed) without editing the resource definition.

Add a default header: key = Accept, value = application/json. AWeber's API returns JSON by default, but specifying the Accept header ensures consistent response formatting.

Click Save Changes. Test the resource by creating a quick query: GET with path /accounts — this should return your AWeber account information including your account ID, confirming that authentication is working.

If you get a 401 Unauthorized response, verify that the AWEBER_ACCESS_TOKEN configuration variable contains a fresh token (AWeber tokens expire after one hour). Regenerate a new token through the AWeber developer portal if needed.

**Expected result:** The AWeber API REST resource is saved with Bearer token authentication configured. A test GET query to /accounts returns your AWeber account data including the account ID, confirming successful connection.

### 3. Query AWeber subscriber lists and build the list overview panel

Create queries to retrieve and display your AWeber subscriber lists. In your Retool app, open the Code panel and add a new query. Name it getLists and select the AWeber API resource.

Set Method to GET. In the Path field, enter /accounts/{{ retoolContext.configVars.AWEBER_ACCOUNT_ID }}/lists. AWeber's API requires the account ID in the URL path for all resource endpoints.

This returns all subscriber lists associated with your AWeber account. Each list includes: id, name, total_subscribers, total_unsubscribers, total_subscribers_subscribed_today, and other counts. AWeber returns paginated results with a next_collection_link for additional pages.

Create a second query named getListStats to retrieve additional performance stats for a selected list. Set Method to GET and Path to /accounts/{{ retoolContext.configVars.AWEBER_ACCOUNT_ID }}/lists/{{ table_lists.selectedRow.id }}/messages. This returns all campaign messages (broadcasts and autoresponders) for the selected list with their delivery and engagement statistics.

Bind the getLists results to a Table component named table_lists. When a row is selected, trigger getListStats to load campaign performance data in a second Table below.

Add a Stat component row above the Table showing summary metrics from the selected list: total_subscribers, total_subscribers_subscribed_today (today's new), and total_unsubscribers. Format these using a JavaScript transformer that extracts the values from the API response.

```
// JavaScript transformer — format AWeber lists for Table component
const lists = (data.entries || []);
return lists.map(list => ({
  id: list.id,
  name: list.name || 'Unnamed',
  total_subscribers: (list.total_subscribers || 0).toLocaleString(),
  total_unsubscribers: (list.total_unsubscribers || 0).toLocaleString(),
  new_today: list.total_subscribers_subscribed_today || 0,
  unconfirmed: (list.total_subscribers_pending || 0).toLocaleString(),
  spam_complaints_today: list.total_spam_complaints_today || 0,
  created_at: list.created_at
    ? new Date(list.created_at).toLocaleDateString()
    : 'N/A',
  web_form_url: list.web_form_url || ''
}));
```

**Expected result:** The lists overview table shows all AWeber subscriber lists with subscriber counts, unsubscribers, and today's new subscribers. Selecting a list row loads the message performance table for that specific list.

### 4. Build subscriber search and management queries

Create queries to search for individual subscribers and manage their status from Retool. Create a query named searchSubscribers. Set Method to GET and Path to /accounts/{{ retoolContext.configVars.AWEBER_ACCOUNT_ID }}/lists/{{ dropdown_list.value }}/subscribers. Add URL parameters:
- key = ws.op, value = findByEmail
- key = email, value = {{ textInput_email.value }}

This searches for a subscriber by exact email match within a specific list. AWeber requires specifying the list when searching subscribers — add a Dropdown component named dropdown_list populated with {{ getLists.data.entries.map(l => ({ label: l.name, value: l.id })) }} to let users select which list to search.

For adding new subscribers, create a query named addSubscriber. Set Method to POST and Path to /accounts/{{ retoolContext.configVars.AWEBER_ACCOUNT_ID }}/lists/{{ dropdown_list.value }}/subscribers. Set Body Type to application/x-www-form-urlencoded (AWeber's subscriber creation endpoint uses form encoding, not JSON). Add the body fields: email, name, and any custom fields your list tracks.

For updating subscriber tags, create updateSubscriber. Set Method to PATCH and Path to /accounts/{{ retoolContext.configVars.AWEBER_ACCOUNT_ID }}/lists/{{ dropdown_list.value }}/subscribers/{{ searchSubscribers.data.entries[0].id }}. The PATCH body includes the fields to update, such as tags as a comma-separated string.

Bind the subscriber search results to a detail panel showing the subscriber's email, name, status, subscription date, and custom field values. Add action buttons for Add Tag, Unsubscribe, and Add to Another List — each triggering the appropriate AWeber API query.

```
// JavaScript transformer — format AWeber subscriber details for display
const subscriber = (data.entries || [])[0];
if (!subscriber) return { error: 'Subscriber not found' };

return {
  id: subscriber.id,
  email: subscriber.email || 'N/A',
  name: subscriber.name || 'N/A',
  status: subscriber.status || 'N/A',
  subscribed_at: subscriber.subscribed_at
    ? new Date(subscriber.subscribed_at).toLocaleDateString('en-US', {
        year: 'numeric', month: 'long', day: 'numeric'
      })
    : 'N/A',
  last_followup_sent: subscriber.last_followup_sent_at
    ? new Date(subscriber.last_followup_sent_at).toLocaleDateString()
    : 'None sent',
  last_followup_number: subscriber.last_followup_message_number_sent || 0,
  tags: Array.isArray(subscriber.tags) ? subscriber.tags.join(', ') : 'None',
  custom_fields: subscriber.custom_fields
    ? Object.entries(subscriber.custom_fields)
        .map(([k, v]) => `${k}: ${v}`).join(' | ')
    : 'None'
};
```

**Expected result:** The subscriber management panel allows searching by email within a selected list. Matching subscribers display their full profile including status, subscription date, tags, and custom fields. Action buttons for tagging and unsubscribing are enabled when a subscriber is found.

### 5. Query campaign performance stats and build the analytics view

Create queries to retrieve detailed campaign performance metrics for your AWeber lists. Create a query named getMessages. Set Method to GET and Path to /accounts/{{ retoolContext.configVars.AWEBER_ACCOUNT_ID }}/lists/{{ dropdown_list.value }}/messages. Add URL parameters:
- key = ws.size, value = 50
- key = ws.start, value = 0

This returns all messages (broadcasts and autoresponders) for the selected list. Each message includes: id, subject, click_tracking_total, open_rate, sent_total, spam_complaints_total, total_opens, total_unsubscribes, created_at, and sent_at.

Create a transformer to format these stats into a clean performance table. Include open_rate as a percentage, calculate CTR from total_clicks / sent_total, and show unsubscribe rate from total_unsubscribes / sent_total.

For message-level detail (click tracking by link), create a query named getMessageClicks. Set Method to GET and Path to /accounts/{{ retoolContext.configVars.AWEBER_ACCOUNT_ID }}/lists/{{ dropdown_list.value }}/messages/{{ table_messages.selectedRow.id }}/links. This returns a breakdown of click counts per link for the selected message.

Bind getMessages results to a Table named table_messages with columns for subject, open_rate, CTR, sent_total, and unsubscribe_rate. Use conditional formatting: highlight rows with open_rate below 15% in yellow and above 30% in green to quickly identify performance outliers.

Add a Chart component using Retool's Bar chart type to compare open rates across the last 10 campaigns, making it easy to spot performance trends visually.

```
// JavaScript transformer — format AWeber message stats for analytics Table
const messages = (data.entries || []);
return messages
  .filter(msg => msg.sent_at) // Only show sent messages, not drafts
  .map(msg => {
    const openRate = msg.open_rate || 0;
    const sentTotal = msg.sent_total || 1;
    const totalClicks = msg.click_tracking_total || 0;
    const ctr = sentTotal > 0 ? (totalClicks / sentTotal * 100).toFixed(1) : '0.0';
    const unsubRate = sentTotal > 0
      ? ((msg.total_unsubscribes || 0) / sentTotal * 100).toFixed(2)
      : '0.00';

    return {
      id: msg.id,
      subject: msg.subject || '(no subject)',
      type: msg.type || 'broadcast',
      sent_at: msg.sent_at
        ? new Date(msg.sent_at).toLocaleDateString('en-US', {
            month: 'short', day: 'numeric', year: 'numeric'
          })
        : 'N/A',
      sent_total: (msg.sent_total || 0).toLocaleString(),
      open_rate: `${(openRate * 100).toFixed(1)}%`,
      click_rate: `${ctr}%`,
      unsubscribe_rate: `${unsubRate}%`,
      spam_complaints: msg.spam_complaints_total || 0,
      total_clicks: totalClicks.toLocaleString()
    };
  })
  .sort((a, b) => new Date(b.sent_at) - new Date(a.sent_at));
```

**Expected result:** The campaign analytics Table shows all sent messages sorted by date with formatted open rate, click-through rate, and unsubscribe rate. Selecting a message loads the link click breakdown. The bar chart visualizes open rate trends across recent campaigns.

## Best practices

- Store AWeber OAuth tokens (access and refresh) as Secret configuration variables in Retool — never paste them into resource authentication fields where they are visible in configuration exports.
- Build a Retool Workflow to automatically refresh AWeber's one-hour access token before it expires, updating the configuration variable so dashboards stay operational without interruption.
- Scope subscriber searches to a specific list using a dropdown selector — AWeber's subscriber model stores contacts per list, and cross-list search requires separate queries per list to avoid missed results.
- Display both confirmed (total_subscribers) and pending (total_subscribers_pending) counts in your list health dashboard — high pending rates indicate deliverability problems with AWeber's double opt-in confirmation emails.
- Use AWeber's message performance data to identify low-engagement campaigns (open rate below 15%) early and trigger list hygiene workflows in Retool to remove or re-engage cold subscribers before they affect your sender reputation.
- Combine AWeber list growth data with your internal business metrics (sign-up source, customer segment) in the same Retool dashboard to understand which acquisition channels produce the most engaged email subscribers.
- Add confirmation prompts before any unsubscribe or tag removal operations — unsubscribing a contact is immediate and irreversible through the AWeber API, and accidentally triggering it cannot be undone without the contact re-subscribing.

## Use cases

### Build a subscriber list health dashboard with growth tracking

Create a Retool dashboard showing all AWeber subscriber lists with total subscriber counts, active vs. unconfirmed counts, 30-day net growth (new subscribers minus unsubscribes), and average open and click rates from recent campaigns. Add a Chart component to visualize subscriber count trends over time for each list.

Prompt example:

```
Build a list health dashboard that queries all AWeber lists, displays subscriber_count, total_unsubscribes, pending_count, and avg_open_rate for each list in a Table, and shows a line chart of 30-day subscriber growth for the selected list using AWeber's subscriber analytics endpoint.
```

### Subscriber lookup and management panel

Build a Retool app where your team can search for any AWeber subscriber by email address, view their subscription status, list memberships, tags, and custom field values. Add action buttons to update tags, change subscription status, or move subscribers between lists — replacing repetitive manual operations in AWeber's UI.

Prompt example:

```
Create a subscriber management panel with an email search input that queries AWeber's subscribers endpoint, displays the subscriber's status, lists they belong to, tags, and custom fields in a detail panel, plus action buttons for Add Tag, Remove Tag, and Unsubscribe that trigger the appropriate AWeber API calls.
```

### Campaign performance reporting dashboard

Build a Retool analytics panel that shows all recent AWeber campaigns (broadcasts and autoresponder messages) with their open rates, click-through rates, unsubscribe counts, and spam complaint rates. Sort by performance to quickly identify top and bottom performing campaigns, and add date range filters to focus on specific time periods.

Prompt example:

```
Create a campaign analytics panel that queries all messages from AWeber's messages endpoint with their stats, displays open_rate, click_rate, unsubscribe_rate, and total_clicks in a Table sortable by open rate descending, and includes a bar chart comparing campaign performance over the past 60 days.
```

## Troubleshooting

### All API queries return 401 Unauthorized after initially working

Cause: AWeber OAuth access tokens expire after one hour. The token in the AWEBER_ACCESS_TOKEN configuration variable has expired and needs to be refreshed using the stored refresh token.

Solution: Use AWeber's token refresh endpoint to obtain a new access token: POST to https://auth.aweber.com/oauth2/token with grant_type=refresh_token and your stored refresh_token. Update the AWEBER_ACCESS_TOKEN configuration variable with the new token value. To prevent this from happening mid-session, build a Retool Workflow that refreshes the token every 45 minutes and updates the configuration variable automatically.

### Subscriber search returns empty entries array for an email that exists in AWeber

Cause: The subscriber search is filtered to a specific list ID. A subscriber may be on a different list than the one selected in the dropdown. AWeber stores subscribers per list — a contact can exist in multiple lists with different status and subscription data for each.

Solution: Search across all lists by creating separate search queries for each list and merging results in a JavaScript query using Promise.all(). Or add a message to the UI indicating that the search is limited to the selected list, prompting users to change the list selection if no results are found. Also verify that the subscriber email is an exact match — AWeber's findByEmail operation requires the full email address with correct case.

### addSubscriber query returns 400 Bad Request

Cause: AWeber's subscriber creation endpoint requires form-encoded data (application/x-www-form-urlencoded), not JSON. Using JSON body encoding returns a 400 error. Additionally, the email field is required and cannot be empty.

Solution: Set the query body type to 'Form' (form-encoded) rather than JSON in the Retool query editor. Ensure the email field in the form body is populated with a valid email address. If your AWeber list uses double opt-in confirmation, newly added subscribers appear with 'pending' status until they confirm via the confirmation email — this is expected behavior and not an error.

### List stats show different subscriber counts than AWeber's dashboard UI

Cause: AWeber's API total_subscribers count returns confirmed (active) subscribers only, while AWeber's UI may show a combined count of active plus pending (unconfirmed) subscribers depending on the view selected. The counts differ when there are pending double opt-in confirmations.

Solution: Sum total_subscribers (confirmed) and total_subscribers_pending (awaiting confirmation) in your JavaScript transformer to calculate the total count matching AWeber's UI view. Display both separately in your Retool dashboard with clear labels to give your team visibility into the composition of each list.

## Frequently asked questions

### Does AWeber have a native connector in Retool?

No, AWeber does not have a native connector in Retool as of 2026. You connect it using Retool's generic REST API Resource type with OAuth 2.0 Bearer token authentication. This means you need to obtain an OAuth access token through AWeber's developer portal and handle token refresh manually or via a Retool Workflow.

### How do I handle AWeber's OAuth token expiry in a team Retool environment?

Create a Retool Workflow that runs on a schedule (every 45 minutes) which POSTs to AWeber's OAuth token endpoint using the stored refresh token to obtain a new access token, then updates the AWEBER_ACCESS_TOKEN configuration variable. This ensures all team members using the Retool dashboard always have a valid token without needing to manually refresh credentials. Store the workflow's execution history to debug any refresh failures quickly.

### Can I add subscribers to AWeber from a Retool form?

Yes. Create a POST query targeting AWeber's subscriber creation endpoint with the subscriber's email, name, and any custom fields your list tracks. Use form-encoded body type (not JSON) as AWeber's subscriber endpoint requires this format. If your AWeber list uses confirmed opt-in (recommended), new subscribers will receive a confirmation email before their status changes from 'pending' to 'subscribed'.

### How do I search for subscribers across all AWeber lists from Retool?

AWeber's API requires a specific list ID in the subscriber search endpoint path — there is no global cross-list search. To search across all lists, first retrieve the list of all lists (GET /accounts/{id}/lists), then make a separate subscriber search query for each list ID using Retool's JavaScript query with Promise.all() to run them in parallel, and merge the results. Display the list name alongside each result so users know which list the subscriber belongs to.

### What AWeber permissions does my OAuth app need for Retool integration?

For a full Retool subscriber management integration, your AWeber OAuth app needs: List Read/Write (to retrieve and modify list settings), Subscriber Read/Write (to search, add, and update subscribers), and Message Read (to retrieve campaign performance stats). When authorizing the app through AWeber's OAuth flow, approve all requested scopes. For read-only reporting dashboards, you only need List Read, Subscriber Read, and Message Read — never request Write permissions if your Retool app doesn't perform write operations.
