here are some steps you can follow: Check API Request & Response: Use a tool like Postman or cURL to directly call the API outside your application. This helps to confirm if the issue is with the API or your application code. Check response codes, headers, and payloads. Review Authentication: API calls often require specific authentication or authorization headers (like API keys or tokens). Use Debugging Tools and Logs: Enable and inspect server or browser logs, and add logging in your code where the API call occurs. Check Network Conditions: Use browser dev tools or network monitors to check for issues like CORS, timeouts, or connectivity problems. CORS issues often arise in web applications when API calls cross domain boundaries.

We should log the requests and responses to & from API. A custom log file with request data & headers should be logged. It will be helpful if we log critical business logic areas without too much exposure of business logic data. Check if any third party integrations are causing issues like once we faced public key issues in production.Also data from these third party integrations should be logged. Sometimes the credentials that we use in API may be the issue. Recheck that. Security headers & CORS can also make issues.

It depends a lot on what the API is there to achieve and who the audience is. Many of the key challenges are similar to more consumer oriented APIs (security, monitoring, quality assurance, rate limits, smooth on-boarding and documentation for users) but more demanding. Security is critical since often these APIs are not just external facing but also provide data to others in the organization which is often more sensitive A mixed user base of internal, close partner and external entities that will use the APIs: in other words often you need to think about multiple audiences with differing levels of access, not just in terms of rate limits but even in terms of visibility of documentation, what APIs there are etc.

Here is an effective approaches that I while for troubleshooting API integration issues : 1. Inspect Response Codes and Messages 2. Check API Key and Authentication 3. Monitor and Review Logs 4. Review Network Traffic 5. Check API Rate Limits 6. Contact API Support

• Review Documentation: Check endpoint and parameter details for proper usage. • Use API Testing Tools: Tools like Postman help isolate issues. • Check Status Codes: Status codes (e.g., 401 for unauthorized) provide quick insights. • Validate Credentials: Ensure tokens are valid and correctly scoped. • Monitor Rate Limits: Avoid hitting request limits. • Enable Logging: Capture request/response details for analysis. • Retry for Intermittent Issues: Use retry mechanisms for temporary failures. • Confirm API Version: Make sure you’re on the correct API version. • Watch for Updates: Keep up with API updates or deprecations. • Seek Support: Use community forums or API support for additional help.

First, you have to ensure you are using the API in the right way: read the documentation if needed. Second, you can log requests and responses for each API request that you make. These two things are going to help you fix almost all the issues.

Use the swagger to debug it and check for authentication and req / resp. Check the api endpoints Data schema And append call back for success.

Absolutely, here’s a simplified approach: 1. Check Documentation: Make sure you’re using the API correctly, as per its documentation. 2. Test the Endpoints: Use a tool like Postman to send test requests and confirm the API’s responses are as expected. 3. Monitor Logs: Look at your application’s logs for any error messages or patterns that could indicate what’s going wrong. 4. Verify Authentication: Ensure your credentials and tokens are correct and not expired. 5. Watch for Rate Limits: Check if you’re hitting any usage limits, which could cause requests to fail. These steps should help you quickly identify and resolve common issues.
