Long story short:

My system need to talk with a 3rd party PoS API. The provided doc is pretty useless and with few errors.. nonetheless I came to finish the 99% of the job.

I was stuckd on the 1%, one frickin function.

Everytime I would call the endpoint I would receive...NOTHING. Just a 200.

I've spent like 5 hours trying everything, even sending wrong params...nothing...
Always 200 and nothing else.

Apparently, for an entire nation and the IT Company behind them, is ok to have A PAYMENT API TO RETURN VOID AND A 200 NO MATTER WHAT.

I got the luck/unluck that the main developer of such piece of art came in the office and I've almost throw him out the window (we are at 26th floor).

FUCK OFF DUDE. YOU AND ALL THE OTHERS THAT DO LIKE YOU DO.

P.S. in this days I'll try to write the full story, but it's hard without giving many details...small anticipation: 1.5 months of work and nothing but red bull and coffee...
