AWS Signature Version 4 for API requests

Hi all,

Does anyone have some Xojo code to generate Amazon Webservices signature v4?

Something to generate the Authorization header that looks like this:

"Authorization: AWS4-HMAC-SHA256 Credential=XXX/20241215/us-east-1/ProductAdvertisingAPI/aws4_request SignedHeaders=content-encoding;host;x-amz-date;x-amz-target Signature=db69c1966b1744b....157ea1c8b" \

Jeremie… my AWS AI classes might help you as all those requests have to be signed… Send me a private message with your email or github name and I will give you access.
