Getting UnknownOperationException while using AWS service catalog API

0

We are trying to build custom application to integrate with AWS service catalog. When trying to hit that endpoint with Postman, but keep getting an error- com.amazon.coral.service#UnknownOperationException .? The error and postman configs are as follows:

Postman Config: Post: https://servicecatalog.us-east-1.amazonaws.com/

Authorization: AWS Signature AccessKey: <AK> SecretKey: <SK> AWS Region: <region> Service Name: servicecatalog

Headers:

X-Amz-Target:AWSServiceCatalog.ListPortfolios Content-Type:application/json ( tried with application/x-amz-json-1.1)

Response: Response code- 200

{"Output":{"__type":"com.amazon.coral.service#UnknownOperationException","message":null},"Version":"1.0"}

if you are writing code with Python, maybe this will be helpful

import boto3

def list_portfolios():
    # Create a service catalog client
    sc = boto3.client('servicecatalog')

    # Call the list_portfolios method
    response = sc.list_portfolios()

    # Print the portfolio details
    for portfolio_detail in response['PortfolioDetails']:
        print(portfolio_detail)

# Call the function
list_portfolios()

but if you want to call via HTTP request, you need to correct Authorization value in the header, it uses AWS Signing key, not AWS Access Key or Secret Key

  • Thank you for your response. We are using Postman to simulate REST API call and using AWS authentication method to sign request where in it generate sign key based on key/secreat before calling AWS service catalog rest API. We can trigger EC2 rest API with same method but issue comes with service catalog API, is there anything we are missing here?
