Validation Preview mode error code changes in the Listings Items API

December 15th, 2025 by SrishtyB_Amazon

The Validation Preview mode of the Listings Items API now returns updated error codes in validation responses. You can use these updated error codes to receive more comprehensive and accurate validation feedback when validating listings.

This change affects only the Validation Preview mode (mode=VALIDATION_PREVIEW query parameter) of the Listings Items API.

What is changing?

The error codes in the issues array of responses have been updated. The validation logic has not changed.

These updates provide the following functionality:

  • More comprehensive validation coverage: Detect more potential issues before submitting your listings
  • Improved validation accuracy: Better consistency between preview validation and actual submission processing
  • Enhanced error detection: Identify issues that may have been missed previously

Who is affected?

Developers with applications that use the Listings Items API are affected by this change.

What action is required?

If your application parses or matches specific error codes from Validation Preview responses, update your code to handle both current and new error codes. Test the integration with the Validation Preview mode of the Listings Items API to observe the new error codes and ensure your application handles them correctly.
