PA API Deprecation by Jan 31, 2026

Hi JSN,

yes, it is quite intimidating that shortly after a month of the Creator API announcement they say that the old system will be fully retired. :/

For what I have understood, the “old” PA API 5.0 is not being fully retired, it just becomes part of the new Creator API (thats a marketing rebrand in my opinion). They just shutdown the old system that uses the S3 feeds. Our plugin should be futureproof as it has been designed from scratch with the PA API 5.0 in mind, that is with Signature V4 S4 authentication method.

What they are really changing in this period is the OfferV2 system, the way their server tell us the price information of the product, and I’m working out an update to make the plugin work with this new system.

We should not be in trouble for now… but developing free projects takes lot of free time and if the next time Amazon does really disrupt its own APIs with these very small timeframes (and jn holidays time!) we will be in trouble for sure. :/

Hi @seljicom ,

I’m still figuring out how to make this plugin compatible with the new creators API (there is more documentation available now and now its more clear what they are updating). The big issue now is that Amazon raised 10x the requirements to be able to access to the APIs. Yes, now they want at least 10 transactions in the last 30 days in the same marketplace and I’m below that threshold. I’ve contacted Amazon but there is now way to get access in other means. So, I cannot currently test any new code and this is braking a lot the development.

In the case that the update is not due before the shutdown of the PAAPI5 dont worry. The products and the data you have already collected through the PAAPI5 will remain in your website and will not disappear. There could be problems adding new products and updating their price info though.

I’m doing my best to fix this as soon as possible but the situation is challenging 😅

Wow, thank you for the compliments, it helps a lot, as I usually see support request and complaints 😀
(Would you mind leaving a positive review?)
By the way, what do you mean to drop off some affiliate links on reddit? Does it work?
I never had luck with that platform and mostly rely on blog traffic but lately I got some issues with SEO and after the christmas peak I got under the new sell threshold, just in time for the API switch :/
( Are you still above the threshold? and so the API access? I’m thinking to organize a closed beta for this API switch )

I will look for reddit but last time it was quite a barren desert in regards of amazon affiliation 😉
I just released the v1.0.15 update with the first implementations of the new Creators API.
If you want to help me just browse the settings page and search for the “Debug mode key” that is “thankyou”. Once saved you will unlock new yellow panels with experimental functions.
If you can help me figuring out if the code for the new Creators API is working you can do it in the new revamped setup page, through a test, and see in the console below if we can get a plausible output.

Sure. I’ve tried configuring the new Creators API in AA. My understanding is that I had to create a connector (application) from within my Tools -> CreatorsAPI (https://affiliate-program.amazon.com/creatorsapi for the NA at least). I’ve assumed that Access Key == Credential Id and Secret Key == Secret from the credentials created within the app. Could you confirm btw?

Yes you have assumed everything right, and remember to thank Amazon for all the clear istructions to do all this passages 😀

Just noticed you’ve mentioned the setup page. So I do see a token (green checks next to all APIs including Creators) and I did get a search item response via both APIs. So looks like its working? 🙂

It look like its starting to work! If you got the response it’s a good signal we are doing everything right! Just to know, are you using an EU or NA marketplace?

@pizza2mozzarella one other thing I’ve noticed today is that I see a red banner indicating I am 80% done with the setup and that I need to complete it. My setup is all green, keys, tests, all green checks – so not sure what else is remaining.

Yes it’s an involuntary bug, with the last version 1.0.15.4 it’s been fixed. That banner should appear when the API test fails, they didn’t fail but the variable got crazy, now it’s ok.

With the last version v1.0.15.4 we can finally choose between the two API sets.
Once setted up and after having selected the new setting, all new products and all freshly updated products will use the new system.

It would be great to have a screenshot or a copypaste of the product field “Api Response”.
This data field is available in the product page (the page where you edit the single product).
