Integration of cryptocurrency payment API and service error diagnostics

The integration of the cryptocurrency payment service API for generating wallet addresses (BTC, ETH, USDT TRC20 / ERC20) on the website side has been completed.

During the work, the following was implemented:
- configuration of the server request to the API via cURL;
- transmission of authorization keys through HTTP headers;
- formation and sending of JSON requests;
- processing and logging of API responses;
- diagnosis of errors in interaction with the service.

During testing, errors from the API provider were identified and analyzed (key format, seed, incorrect address generation, 502 Bad Gateway errors).

A detailed analysis of the logs was conducted, and technical information was provided for further diagnosis on the provider's side.

Technologies:
PHP, cURL, JSON API, HTTP headers, logging of server requests.
