I have to use AWS REST API to work with various cloud services. Initially, I'm trying in postman tool to fetch the list of repositories from AWS CodeCommit. I'm following this link https://docs.aws.amazon.com/codecommit/latest/APIReference/API_ListRepositories.html to accomplish my task. I have problem on setting the authorization for this API call. I have provided both access and secret keys and the region. I could not get the repository lists instead facing 503 network issue.

UPDATE

I'm facing the following error message

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

  1. In Postman, select the POST method and put URL as 'https://codecommit.us-east-1.amazonaws.com/'
  2. Go to Headers and add
  • 'Content-Type' key and 'application/x-amz-json-1.1' as the value
  • 'X-Amz-Target' key and 'CodeCommit_20150413.ListRepositories' as the value
  • 'Host' key and 'codecommit.us-east-1.amazonaws.com' as the value
  1. Go to the 'Authorization' tab and configure the AWS Signature type as follows:
  • AccessKey: xxxxxxxxxxxxx
  • SecretKey: xxxxxxxxxxxxx
  • AWS Region: us-east-1

  1. Go to 'Body' tab and type {}

  2. Click 'Send' to test

Note: Make sure to use correct region in all the place above (us-east-1 as example).
