Encountered a bug during the prepayment on the store's website. It gives a 400 error, everything was working fine before, then the token for the FOP was changed. Full payment works. Need to check what the problem is and verify if our modules are okay. We are working with Monobank.

I can help figure out the 400 error when making a prepayment through Monobank. I will check the correctness of the token, API requests, and modules to ensure everything is working stably. It seems the problem is local — solvable within a day. I have a couple of clarifying questions about the system and payment logic, I will write in private messages.

Hello.
I have extensive experience in integrating and debugging payment APIs from Monobank, including handling token-based authentication and prepayment verification processes. The 400 error you encountered likely indicates an issue with the token or the request payload. I can quickly identify and resolve it by checking the API logs and module configurations. I will ensure the proper functioning of the prepayment and full payment modules after the token change. With my experience in integrating payment gateways and e-commerce systems in PHP, I will be able to effectively restore the seamless operation of payment transactions in your store.
