AWS Presigned URLs for Services Other than S3?
There is a big unsolved mystery: Is it possible to create pre-signed URLs for AWS services other than S3? For example, is it possible to create a pre-signed URL that allows the user to send an SES email?
We simply don’t know. Theoretically it seems it should be possible. However, all AWS pre-signed URL documentation or examples has to do with S3 uploading or downloading objects.
