Troubleshooting UPark API Error 500 frequency related to transaction validation codes. Focus: TLS/SSL, API response codes, JSON parity, caching.
Response time is a key indicator of server load.
Specific patterns can point to data validation issues.
Expired certificates will cause communication failures.
API communications rely on TLS/SSL for secure data transmission. 500 responses may indicate issues with the API server's ability to handle requests, potentially due to high server load, database connectivity problems, or code defects. Validation code processing adds an additional layer of complexity, increasing the potential for errors during data validation and integrity checks. This can be affected by inconsistent JSON parity between the request and response. Cache invalidation problems on the validation code server can also produce intermittent errors. DNS resolution latency can contribute to timeout errors resulting in a 500 error.
Regularly monitor API server performance metrics and logs. Implement automated testing to verify the functionality of validation code processing logic. Keep TLS/SSL certificates up-to-date. Ensure sufficient server capacity to handle peak transaction volumes. Monitor DNS resolution times for all relevant services.
Utilize API monitoring tools to track the frequency of Error 500 responses specifically for validation code transactions. Analyze the request/response payloads associated with these errors to identify potential data format issues or code defects. Implement distributed tracing to pinpoint the source of the error within the API call stack.
