A POST request fires. Talkable checks the response. Until now, that check couldn’t happen through Custom App.
The Check Unsubscribe action was the last webhook type that couldn’t be replaced with a Custom App action. Teams relying on custom unsubscribe logic had to keep the legacy check_unsubscribe webhook running alongside their Custom App setup — a fragmented approach with no clean consolidation path.
We’ve added a native Check Unsubscribe action to Custom App, so you can handle all webhook logic in one place.
Here’s what you can do:
- Add a check_unsubscribed action in the Custom App editor and configure your endpoint URL
- Talkable sends a request with Site ID, Person, Campaign, and email_type — your endpoint returns unsubscribed: true/false
- If the request fails or no response is received, it defaults to false (subscribed) — keeping your program running safely
- The legacy check_unsubscribe webhook remains as a fallback when no Custom App action is defined
Your Custom App integration is now complete. Every webhook type Talkable supports can be handled through a single, unified setup.
