Is there any issue with API endpoint or action here?
Hey @pradeep.rode121 
Is there any information in here that can help?
Thank you Danny for your response. I did tried following link it did not work.
I am using AWS service catalog public APIs and passing required parameter for AWS below but still its giving unknownoperationerror
X-Amz-Target:AWS242ServiceCatalogService.ListPortfolios
Content-Type:application/x-amz-json-1.1
Our help here is going to be quite limited unless a forum member knows all about that API.
This isn’t a Postman functionality issue as it looks like you’re getting a response from the server so I’m unsure where you could go from here.
Posting a question on the AWS forum might help:
