Integrating a Third-Party Service

It allows multiple HttpClient instances to be created per call It manages handler lifetimes to prevent socket exhaustion It simplifies the authentication process for API calls It enhances the performance of all API requests

Tightly map their API response directly into your domain models Ignore all changes and handle them at the moment of failure Use tolerant deserialization to ignore unknown fields Automatically update your code base whenever their API changes

Using the same credentials for sandbox and production environments Recording all call payloads in logs for debugging Ensuring separate key vaults for sandbox and production to manage secrets Using default base URLs in the code to avoid errors

Only log error messages for failed requests Establish alerts only for critical outages Monitor API error rate and latency per operation Ignore monitoring if the users report issues
