Webhooks

Webhooks allow your application to listen to the following events from Bumper:

• Applied

  • The customer has applied for PayLater

• Signed

  • The customer has added card details and been accepted

• Updated

  • The application has been updated

• Cancelled

  • The application has been cancelled

Your webhook must return an HTTP 200 response to avoid unnecessary retries.
