In S3, we have special behavior for Signature Validation, something we don't do for other services.
We have supported pre-signed URLs signature validation for a long time now, but we didn't have a lot of documentation in how to best use it, which credentials to use and what are the limitations.
We recently also added signature validation for all requests, not only pre-signed for a prospect (Canva).
This felt like the right time to add documentation about both feature together as they are closely related and share some logic about which credentials you should use.
