Hey @desarrollador,
Please test your API keys on Amazon’s site.
You can go to
https://webservices.amazon.com/paapi5/scratchpad/index.html
Click on GetItems in the left sidebar
Fill in your API key,m API secret, and your tracking ID/partner tag.
Fill an ASIN under ItemIDs, and as resource select for example ItemInfo.
Then you click the RunRequest button and you will either get an error or the product information in JSON format.
If you see the same error there you confirmed that it’s an issue with the API key, maybe Amazon blocked the API key for whatever reason.
If you don’t see the error there you confirmed that it’s an issue with the AAWP plugin and we would really like to investigate further if that’s the case. But so far, every single time, it’s been Amazon blocking the API key. We don’t know all the reasons why Amazon would block an API key, I recommend contacting their support about that if that is the case.
