404 on api endpoint when invoked from a webhook client

I have a nodeMCU with Blynk installed, and working well. I have added a virtual pin, and i am able to write data to it using the GET API as below.


I added the URL as a webhook in bitbucket to trigger the pin when someone pushes a commit. It calls the URL, but the request gets a 404 response. The same URL works fine directly in the browser, and in REST clients.

I tried switching out blynk-cloud.com domain with its IP (, but that didn’t help either.

What am I missing here?!
