Amazon is actively migrating to the new Creators API and retiring certain features of the Product Advertising API 5.0 (PA API). On January 31, 2026, the “Offers V1” functionality within PA API 5.0 will be retired, and developers must use the Creators API’s “Offers V2” endpoint instead.
While Amazon has not announced a complete shutdown date for PA API 5.0, the trend is clear: Creators API is the future. ASA2 will fully support the Creators API to ensure your site remains future-proof.
What Does This Mean for You?
The good news: No immediate panic required. PA API 5.0 remains functional for now, but Amazon is clearly pushing developers toward the Creators API. The new API brings significant improvements, including more detailed deal information (Offers V2) and modern OAuth 2.0 authentication.
ASA2 Creators API Integration: Already in Testing
We’re well ahead of the curve. The Creators API integration for ASA2 is already in active development and testing. Here’s what the new setup interface looks like:
The new Creators API setup form in ASA2 – currently in testing phase. You’ll be able to configure your Credential ID, Credential Secret, and Region Version here.
Updated PA API Setup Form
When Creators API is active, ASA2 automatically manages the transition – the PA API setup shows an inactive status with a clear notice, preventing any configuration conflicts.
These screenshots demonstrate that ASA2 will provide a seamless setup experience with automatic fallback handling between PA API 5.0 and Creators API.
What You Need to Know
To future-proof your ASA2 installation, there is one important change that requires your action:
You Must Create New API Credentials
Your existing PA API credentials (Access Key and Secret Key) cannot be used with the Creators API. Amazon has introduced a completely new credential system:
- Instead of Access/Secret Key: Credential ID and Credential Secret
- New Authentication: OAuth 2.0 instead of AWS Signature
- Marketplace-Specific: Credentials are tied to your Amazon Associates marketplace
Technical Requirements
To use the Creators API, you need:
- PHP 8.1 or higher – This is a requirement from Amazon for the Creators API SDK
- ASA2 Version 1.29.0 or higher – Coming soon
If your server is still running PHP 7.4 or 8.0, please talk to your hosting provider about an upgrade. Most hosting providers already offer PHP 8.1+ as standard.
How to Prepare for Creators API
Step 1: Understand the Timeline
January 31, 2026: Amazon retires “Offers V1” within PA API 5.0. After this date, offer data will only be available via Creators API’s “Offers V2” endpoint.
Beyond January 2026: PA API 5.0 continues to function (except Offers V1), but Amazon is clearly moving toward Creators API as their primary platform.
Step 2: Check Your PHP Version
Creators API requires PHP 8.1 or higher. Check in your hosting control panel or with your hosting provider whether this version is available. Most modern hosting providers offer PHP 8.1+ as standard, and upgrading is usually done with just a few clicks.
Step 3: Create Creators API Credentials (When Ready)
Log in to your Amazon Associates account and create new Creators API credentials. Detailed instructions can be found in the Amazon Associates Central documentation.
The links to the PartnerNet pages for each country can be found below.
Step 4: Update to ASA2 1.29.0 (Coming Soon)
Once ASA2 Version 1.29.0 is released, you’ll find a new setup form for the Creators API in the plugin settings where you can enter your new credentials. The update will include full support for Creators API alongside continued PA API 5.0 compatibility.

Frequently Asked Questions
Can I continue using my existing PA API credentials?
Yes, for now. PA API 5.0 remains functional, but to use the Creators API (which is the future), you must create new credentials. The old Access/Secret Keys will not work with the Creators API.
What exactly changes on January 31, 2026?
Amazon is retiring the “Offers V1” functionality within PA API 5.0. To continue accessing offer data, you must migrate to the Creators API’s “Offers V2” endpoint. ASA2 will handle this transition automatically once you’ve configured Creators API credentials.
Will PA API 5.0 be completely shut down?
Amazon has not announced a complete shutdown date for PA API 5.0. However, the trend is clear that Creators API is the future platform. We strongly recommend migrating to ensure your site remains compatible with Amazon’s evolving infrastructure.
Do I have to pay extra for the Creators API?
No, the Creators API is free for Amazon Associates, just like the PA API 5.0. ASA2 itself requires no additional cost for Creators API support.
What happens if my server doesn’t support PHP 8.1?
You can continue using PA API 5.0 for now (which works with PHP 7.4+), but to use the Creators API in the future, you’ll need PHP 8.1 or higher. We recommend upgrading your PHP version soon to ensure a smooth transition when you’re ready.
When will ASA2 Version 1.29.0 with Creators API support be released?
We are working hard on the implementation. The version will be released well before January 31, 2026. Stay informed via our blog and plugin update notifications.
Conclusion: Be Prepared for the Future
The migration to the Creators API is an important evolution in Amazon’s product advertising platform. While there’s no immediate deadline for a complete PA API 5.0 shutdown, being proactive ensures you’re ready for Amazon’s future direction.
We recommend taking these steps at your convenience:
- Monitor your PHP version: Check if your server supports PHP 8.1+ (required for Creators API)
- Create Creators API credentials: Get them from your Amazon Associates account when you’re ready
- Install ASA2 1.29.0: Once released, update and configure Creators API credentials
Timeline flexibility: PA API 5.0 remains functional beyond January 31, 2026 (except for Offers V1). You can migrate to Creators API when it suits your schedule, but we recommend doing so sooner rather than later to stay aligned with Amazon’s platform evolution.
We will publish further details and a comprehensive migration guide when ASA2 1.29.0 is released. If you have questions, please use our support forum.
