callback_url_already_registered_for_broker

Description ​

The callback URL is already registered for this broker.

HTTP Status ​

409 Conflict

doc_url Format ​

The doc_url value is an absolute URL and changes by environment:

<docs-base-url>/errors/callback_url_already_registered_for_broker

Typical Causes ​

  • The same registration request was submitted more than once.
  • The client retried a successful registration without checking existing state.
  • A second registration was attempted with the same callback URL for the same broker.

How To Fix ​

  1. Reuse the existing registration if this callback URL is already registered.
  2. Use a different callback URL if a new registration is required.
  3. Retry only after confirming the broker does not already have that registration.
