I am currently testing our integration in the Sandbox environment and am encountering an issue where webhook notification retries are not triggering as expected.
The Scenario: According to the Fireblocks documentation, if a webhook endpoint does not return an HTTP 200 response, Fireblocks should resend the request using an exponential backoff schedule (starting at 15s, 45s, etc.).
For testing purposes, I have intentionally configured our receiver to return no response (simulating a service down). However, after the initial delivery attempt fails, I do not see any subsequent retry attempts in our server logs, nor does the Fireblocks Console indicate that a retry cycle is active.
