Uploading and accessing a public asset image

[Daniel_Y]

Hello, I am having issues accessing a public asset image that I have uploaded. These are the steps I've taken to upload it:

1. Send an upload URL request (/api/v2/uploads/publicassets/images) to get a presigned upload URL:

{
   "fileName": "winter_phone.jpg",
   "contentType": "image/jpeg"
}

NOTE: "https://" has been replaced with (insert-https-here) and "s3://" has been replaced with (insert-s3-here)
API Response (security token and signature have been edited):

{
  "url": "(insert-https-here)fileupload.euw2.pure.cloud/uploads/v1/publicassets/images/6b6e4616-5247-41b8-8121-aefc30b12b93/0843276e-8581-408d-8742-f11e06a6a2db.winter_phone.jpg?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=ASIA3EQYLGB76N25HWAE%2F20230908%2Feu-west-2%2Fs3%2Faws4_request&X-Amz-Date=20230908T093015Z&X-Amz-Expires=600&X-Amz-SignedHeaders=content-type%3Bhost%3Bx-amz-meta-organizationid%3Bx-amz-tagging&X-Amz-Security-Token=my-security-token&X-Amz-Signature=my-signature",
  "fileUrl": "(insert-s3-here)public-assets-uploads-prod-euw2/uploads/v1/publicassets/images/6b6e4616-5247-41b8-8121-aefc30b12b93/0843276e-8581-408d-8742-f11e06a6a2db.winter_phone.jpg",
  "uploadKey": "uploads/v1/publicassets/images/6b6e4616-5247-41b8-8121-aefc30b12b93/0843276e-8581-408d-8742-f11e06a6a2db.winter_phone.jpg",
  "headers": {
    "x-amz-tagging": "organizationId=6b6e4616-5247-41b8-8121-aefc30b12b93&originPlatform=GenesysCloud&role=darth&owner=Dev-CloudAppsDarth@genesys.com",
    "x-amz-meta-organizationid": "6b6e4616-5247-41b8-8121-aefc30b12b93",
    "Content-Type": "image/jpeg"
  }
}

2. Upload the image by doing the following PUT request (using curl):
   curl -X PUT -T "C:\Users\GRIGS\Pictures\winter_phone.jpg" "(insert-https-here)fileupload.euw2.pure.cloud/uploads/v1/publicassets/images/6b6e4616-5247-41b8-8121-aefc30b12b93/0843276e-8581-408d-8742-f11e06a6a2db.winter_phone.jpg?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=ASIA3EQYLGB76N25HWAE%2F20230908%2Feu-west-2%2Fs3%2Faws4_request&X-Amz-Date=20230908T093015Z&X-Amz-Expires=600&X-Amz-SignedHeaders=content-type%3Bhost%3Bx-amz-meta-organizationid%3Bx-amz-tagging&X-Amz-Security-Token=my-security-token&X-Amz-Signature=my-signature" -H "x-amz-tagging: organizationId=6b6e4616-5247-41b8-8121-aefc30b12b93&originPlatform=GenesysCloud&role=darth&owner=Dev-CloudAppsDarth@genesys.com" -H "x-amz-meta-organizationid: 6b6e4616-5247-41b8-8121-aefc30b12b93" -H "Content-Type: image/jpeg"

I get an empty 200 OK response.

What is the URL of the image supposed to be after it's uploaded? I tried (insert-https-here)api-cdn.euw2.pure.cloud/uploads/v1/publicassets/images/6b6e4616-5247-41b8-8121-aefc30b12b93/0843276e-8581-408d-8742-f11e06a6a2db.winter_phone.jpg ((insert-https-here)api-cdn.euw2.pure.cloud/{uploadKey}), but I get an
"Access Denied" error. However, I can access an image uploaded via the UI (a Messenger Configuration bot picture) just fine: (insert-https-here)api-cdn.euw2.pure.cloud/uploads/v1/publicassets/images/6b6e4616-5247-41b8-8121-aefc30b12b93/3328480c-d9e6-4a60-b9f9-aac55a288f7a.this_is_an_image.jpg

I'm assuming you used the browser's Developer Tools to monitor exactly what Genesys Cloud is doing, for instance when you upload a logo to be used by Web Messaging Configuration?

I'm not an expert with this API, but I'd have to guess that the Access Denied error has something to do with one of two things...

1. Either the "Amz" security tokens, signatures, etc that you are using are not correct.

or the more likely reason

2. Only Genesys internal OAuth clients can be used to upload that content to eliminate any rouge actors from sniffing the network traffic of Genesys Cloud and uploading public assets that could contain security vulnerabilities.
