Amazon Ads has announced an important update for developers and advertisers using their Sponsored Products API. The v3 content type for theme-based bid recommendations will be deprecated, with the change taking effect on May 15, 2025.

Key Points:

1. Deprecation Target: The content type application/vnd.spthemebasedbidrecommendation.v3+json for Sponsored Products theme-based bid recommendations will be phased out.

2. Effective Date: The deprecation will take effect on May 15, 2025, giving users over a year to make necessary adjustments.

3. Recommended Action: API callers are encouraged to transition to the newer application/vnd.spthemebasedbidrecommendation.v4+json content type.

This deprecation is part of Amazon's ongoing efforts to improve and streamline their advertising APIs. The move to v4 likely includes enhancements or changes to the data structure for theme-based bid recommendations.

Advertisers and developers using the Sponsored Products API should plan to update their integrations well before the deprecation date to ensure uninterrupted access to theme-based bid recommendations.

Amazon has not provided specific details about differences between v3 and v4 in this announcement. Users are advised to consult Amazon's developer documentation for more information on implementing the v4 content type in their API calls.
