I hate API like this

- This is Microsoft.
- He returns Webhook success with a code 200 and plaintext 1.
- He returns Webhook failure with a code 200 and a string tells its endpoint returned error 400.
- the string didn't tell what exactly the error.
- Don’t be like Microsoft.
EDIT: Got a few details wrong since this happens a few months ago and this meme used to be on r/ProgrammerHumor. Also the proof: 
The quality of Microsoft APIs is legendary... if you just take a minute to study win32, you will be always glad that those webserver responses are the kind of shit you have to deal with.
But to be fair, this looks exactly like a well designed API that somebody pushed behind a corporate firewall.
