Paytr  Documentation Is Useless, Customer Service Uncooperative

Integrating with Paytr is the last thing you'd want to do for payment systems. Wondering why? They don't directly open up their API to anyone, but you won't find this mentioned anywhere. They ask you to set up the system, provide a demo account (from completed code), and their documentation is utterly incomplete. The parameters you send and the ones the API receives don't match, and the response is equally baffling. Error messages come in that aren't even listed in the error code directory. Sample codes are either completely missing or half-baked. It's like trying to solve a puzzle blindfolded. The whole experience is like building a house of cards in a windstorm. I can't wrap my head around how they expect developers to work with such an uncooperative and poorly documented system. It's a headache, and I wouldn't recommend it to anyone in the field.
