API Integration: Error Code Classification and Handling Strategies

The Importance of Proper Error Code Handling



Indiscriminate retries place excessive strain on the API; correctly interpreting error codes allows for the rapid differentiation of issues originating from the business application, the platform, or the carrier.

Error Identification and Handling



1. Permanent Errors


  • Invalid numbers or incorrect formats; retries are prohibited.

  • Flag the number as anomalous and store it in the application's exception database.


  • 2. Temporary Errors


  • API rate limiting or carrier outages; retries are permitted within defined limits.

  • Implement exponential backoff; high-frequency, continuous retries are prohibited.


  • 3. Implementation Requirements


  • Map platform error codes within the business system and fully log the error causes.

  • Do not rely on successful API submission as the final outcome; always base status on the delivery receipt.

  • Establish a monitoring dashboard to enable timely intervention and troubleshooting for frequent exceptions.
