Define the source bucket for the request
To define the bucket used when getting the image for a request, include s3:BucketName as a modification in your request. For example, if your source buckets were "test-bucket-1, the-other-test-bucket", to indicate that the-other-test-bucket should be used when processing an image, enter the following:
https://<ApiEndpoint>/s3:the-other-test-bucket/<image.jpeg>
Note
Using the s3:BucketName tag requires that the bucket chosen is part of the SourceBuckets provided upon deployment. For information on how to change the SourceBuckets after deployment, see Backward compatibility.
