To troubleshoot API integration issues, I first review the API documentation for proper implementation and common errors. Then, I test endpoints individually to isolate problem areas. Logs are analyzed for error codes, and any changes in third-party services or versions are checked. Tools like Postman help validate requests.

When your web application is facing an API issue there may be multiple reasons of this. So, always refer to the official documentation first. - Before starting the integration use API testing tools like postman and carefully test all the APIs. - First and foremost thing make sure you've right credentials for the API and it the API is limiting usage whitelist your domain/ip from the panel. - If you're using any third-party package to interact with APIs, check the integration of the package. It might be possible the package itself has bug and API is working. - Always log your error response and check the log files daily. In that way you wil have idea about which part of your application is facing major issues. Do debugging and coding.

API integration issues? Classic. First, check the basics—keys, endpoints, and if someone "helpfully" changed the API version (again). Next, log everything—because if it’s not logged, it didn’t happen. Then hit Postman or cURL to test calls manually. If the API docs are as clear as mud, don’t be shy—reach out to their support team (and maybe send them coffee). Finally, debug step-by-step, and don’t rule out that it’s a network gremlin. Fix it, test it, and celebrate with a commit message that says “Fixed API bug, definitely this time.”

Double-Check the Docs 📚: Revisit the API documentation to ensure you’re using the endpoints, parameters, and authentication correctly. Sometimes, the answer is hidden in the fine print! Test One Endpoint at a Time 🔍: Use tools like Postman or curl to test individual API calls. This helps isolate whether the issue is with a specific endpoint or your app’s implementation. Look for Updates or Changes 🔄: Check if the third-party service recently updated the API or deprecated features. A small change on their end can cause big issues on yours.

To ensure good integration with APIs, always pay attention to release notes, documentation and new versions. API's can often have breaking changes or changes that can compromise the integration. To ensure that everything is happening perfectly, pay attention to observability, monitor errors (e.g. Sentry, TrackJS), perform integration tests on your pipeline.
