I'm starting to develop a simple Symfony 5 application. It uses Amazon Product Advertising API 5.0 with the paapi5-php-sdk package (provided by TheWirecutter, since Amazon pulled it from Packagist, but this is irrelevant).
I've a 5 years old Associate account, and I already generated fresh Access+Secret keys.
Since I'm in Italy, I'm hitting webservices.amazon.it+eu-west-1.
I've ran, like, 10 API calls in the last 24 hours, but the service always respond:
TooManyRequests Error Message: The request was denied due to request throttling. Please verify the number of requests made per second to the Amazon Product Advertising API.
I'm aware of the rating limiting, but I'm nowhere near the lowest limit.
What am I doing wrong?
