# How to Automate Patreon to ESP Segment Sync using the API

- Tool: API Automations
- Difficulty: Intermediate
- Fix time: 60 minutes
- Compatibility: Patreon API v2 — OAuth2 with campaigns.members and campaigns.members[email] scopes
- Last updated: May 2026

## TL;DR

Fetch all Patreon members with email via GET /api/oauth2/v2/campaigns/{id}/members?fields[member]=full_name,email,patron_status,currently_entitled_amount_cents&include=currently_entitled_tiers, paginate via links.next cursor, then segment active/declined/former patrons into your ESP (Mailchimp, ConvertKit, Beehiiv). Critical: without the campaigns.members[email] scope, the email field is silently absent — no error, just missing data.

## Best practices

- Always specify fields[member]=email,... explicitly — without it, email is absent from responses with no error
- Add User-Agent header on every request — omitting it returns 403 that looks like an auth error
- Handle all three patron_status values: active, declined, and former — leaving declined patrons in active segments hurts email deliverability
- Use upsert operations in your ESP rather than create-or-skip to keep data current as patrons change tiers
- Add 500ms delays between Patreon pagination requests to stay safely within undisclosed rate limits
- Run the sync daily in the early morning hours — most patron status changes occur during Patreon's monthly billing cycle
- Log sync counts and check for anomalies — a sudden 20% drop in synced contacts likely means a scope or API issue

## Frequently asked questions

### Why are all my member contacts missing email addresses?

You're missing the campaigns.members[email] scope. Without it, Patreon silently omits the email field from all member responses — no 403, no error message, just an absent field. Regenerate your OAuth client with this scope explicitly requested and re-authorize. This is the #1 issue reported when building Patreon ESP syncs.

### How do I get the campaign ID for the members endpoint?

Call GET /api/oauth2/v2/campaigns with your Creator's Access Token. The response includes your campaign's ID. For a creator with one campaign, this is a one-time lookup — store the ID as a constant rather than fetching it every sync run.

### Should I remove former patrons from my email list entirely?

Don't unsubscribe them immediately — they're a warm audience. Instead, move them to a 'Former Patron' segment and run a re-engagement campaign over 30-90 days. Only unsubscribe (or suppress) if they haven't re-subscribed after your re-engagement attempt or if they explicitly unsubscribe from your ESP.

### How do I handle patrons who change tiers?

The daily sync handles tier changes automatically — the members endpoint always returns currently_entitled_tiers. On the ESP side, upsert the contact with the updated tier tags. In Mailchimp, use the member PUT endpoint which overwrites existing tag state when you include the tags array.

### What's the difference between declined_patron and former_patron?

A declined_patron had a payment failure — their card was declined, expired, or insufficient funds. They haven't cancelled; they may recover. A former_patron has explicitly cancelled their pledge or had their membership removed. Treat declined as recoverable (win-back sequence), former as churned (re-engagement or sunset).

### Can I sync to ConvertKit instead of Mailchimp?

Yes. ConvertKit uses tags rather than list segments. After fetching Patreon members, use ConvertKit's POST /v4/subscribers endpoint to create or update subscribers, adding tags like 'Active Patron', 'Gold Tier', etc. ConvertKit's API v4 uses an API key (CONVERTKIT_API_KEY) in the Authorization header.

### How often should I run the sync?

Daily is appropriate for most campaigns. Patreon's billing cycle is monthly, so member status changes are concentrated around billing dates. Running more frequently adds API load without significant benefit. For real-time new-member onboarding, use the members:create webhook in addition to the daily full sync.
