Callback URL

A URL you provide to a third-party service so it can notify your automation when an async task completes. Common in payment systems Stripe calls your callback URL when a payment succeeds, triggering your invoice workflow.

Expert insight

A callback URL that isn't validated on the receiving end (checking the request actually came from the expected service, via a signature or shared secret) is an open door for anyone who discovers the URL to trigger the workflow with fabricated data. Callback endpoints need the same authentication scrutiny as any other public-facing endpoint.

In a real workflow

A document signing service calls your callback URL when the contract is signed, which triggers onboarding.
