Cannot connect to german "DE" region

[herzit]

Hey guys,

I followed your installtion / setup-instructions but cannot connect to the amazon product API. Either I'll get a 400 or 503 error code.

The only thing I don't get: If I only need my data from my associate account

Before you get started, make sure you have both Amazon Product Advertising and AWS accounts. AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_ASSOCIATE_TAG are all from your Amazon Associate Account.

why do I need an AWS account? Currently I'm using the key, secret key and associate tag from my amazon associate account and it doesn't work, unfortunately. I also tried to generate the same keys, except the associate key, within my AWS account and tried to connect but without any success. Can you explain why we need both accounts? (AWS and Associates)

I haven't set a payment option within my AWS account but I'm able to use it and create my keys. May this be a problem?

I'm really looking forward for any kind of help. It's really needed.

Thanks guys for contributing, really appreciate it.

Best regards

Effective 23-Jan-2019, the usage limit for each account is calculated based on revenue performance attributed to calls (also called requests) to the Product Advertising API (PA API) during your account’s latest 30-day trailing period. ...
Each account used for Product Advertising API is allowed an initial usage limit up to a maximum of 1 request per second and a cumulative daily maximum of 8640 requests per day (TPD) for the first 30-day period after your account has been approved. ...
Note that your account will lose access to Product Advertising API if it has not generated referring sales for a consecutive 30-day period.

Maybe you didn't generate enough revenue for german "DE" region in the past and so you lost access.
