For curbing in above mentioned scenario, and to get out quickly with solution, use
RequestBin.
This super-cool interface gives you a URL that will collect requests made to it and let you inspect them in a human-friendly way.
You can also use RequestBin to see what your HTTP client is sending or to inspect and debug web-hook requests.
Would recommend to try it out once. Do share if you find this useful.
Happy Azure coding!
