A: Hi internetmogul,

Thanks for your question!

Diaflow can connect to APIs that use OAuth2, including Amazon Seller or Amazon Advertising APIs, by using the HTTP Request node. You can configure OAuth2 settings within this node to authenticate your calls. Here's the documentation for reference:
👉 HTTP Request Node – https://docs.diaflow.io/flows/component-reference/built-in-tools/http-request

Let us know your exact use case and we’ll be happy to help guide you through the setup!

Best regards,
Diaflow CS Team
