React to connection lifecycle events

Some integration work should happen around the connection lifecycle rather than from a user action or schedule. For example, you may need to verify credentials before accepting a connection, register provider webhooks after authorization, or clean up subscriptions before a customer disconnects.

Tenklo supports this with event functions. They run automatically for a specific integration and connection event.

When this fitsCopy Anchor Link

Use event functions when you need to:

• Validate credentials or provider permissions during connection creation.
• Register external webhook subscriptions after a connection is created.
• Fetch account context and store it as connection metadata.
• Clean up provider resources before a connection is deleted.

These functions are not called by your app directly. Tenklo runs them when the configured lifecycle event occurs.

How Tenklo fits inCopy Anchor Link

1. Your user creates or deletes a connection.
2. Tenklo detects the lifecycle event.
3. Tenklo runs the event function with that connection's credentials.
4. The function validates, initializes, registers, or cleans up provider-side resources.
5. The execution appears in Tenklo logs.
