Stripe ➔ Notion API Payload Specification

Technical reference for automating data exchange between Payments and Workspace workflows.

💡 How this integration works:

1. Stripe triggers an event when checkout.session.completed occurs.
2. Data is packaged into a standard JSON webhook payload.
3. Payload is delivered into your Notion API intake pipeline and mapped to your Workspace targets.
