Amazon Creators API
Starting with version 1.29.0, ASA2 fully supports Amazon's new Creators API. This API is the successor to the Product Advertising API (PA API) 5.0 and offers enhanced features for affiliate product data.
INFO
PHP 8.1+ required: The Creators API requires PHP 8.1 or higher. If your server runs an older version, ASA2 will automatically use PA API 5.0 instead. See Php Version Requirements for details.
What is the Creators API?
The Creators API is Amazon's next-generation API for affiliate publishers. It provides access to product information, pricing data, and affiliate links. Amazon is gradually transitioning from PA API 5.0 to the Creators API.
Key benefits of the Creators API:
- Offers V2 format: Enhanced pricing data with more details about deals and availability
- Per-marketplace credentials: Separate API credentials for each Amazon marketplace
- Cognito (v2) and LWA (v3) support: Works with both existing Cognito credentials and newer LWA (Login with Amazon) credentials issued since February 2026
- Improved data quality: More accurate and comprehensive product information
- Future-proof: Amazon's recommended API going forward
Important Timeline
WARNING
January 31, 2026: Amazon will retire the Offers V1 format in PA API 5.0. After this date, PA API will no longer return pricing data in the V1 format. We recommend setting up Creators API credentials before this deadline.
How ASA2 Handles API Routing
ASA2 automatically selects the best API for each request based on your configuration:
| Scenario | API Used |
|---|---|
| Creators API enabled | Creators API |
| Creators API disabled | PA API 5.0 |
| No Creators credentials | PA API 5.0 |
| PHP version < 8.1 | PA API 5.0 |
This means you can gradually migrate to the Creators API marketplace by marketplace. Your existing products will continue to work during the transition.
ASA2 supports both Cognito (v2) and LWA (v3) credentials. The API version is automatically determined based on your credential type and marketplace region:
- Cognito (v2) credentials use API versions 2.1–2.3
- LWA (v3) credentials use API versions 3.1–3.3
