How to use Amazon SP API credentials in n8n?

Hi all,

I already have the Amazon SP API credential.

I want to connect to the Amazon Selling Partner API using these in n8n, but I’m not sure how to structure the authentication.

What’s the best way to use these credentials in n8n? Do I need to handle the signing and token manually in Function/HTTP Request nodes, or is there a better method?

Thanks in advance!
