PHP Integration: 1xbet Mobcash API

I need a PHP developer who can take the Mobcash API documentation and keys that I already have and wire them directly into my existing 1xbet‐style site. The goal is very clear: deposits and withdrawals must be triggered and posted back automatically without manual intervention...
