How to use AWS Translate "TranslateText" API via POSTMAN

Question

I am building a POC using AWS Translate and one of the requirement is to use REST API.

I have constructed the below url :

but when I hit the url using POSTMAN I get the below error :

{
    "__type": "UnknownOperationException"
}

Answer 1

I have managed to find a fix to my issue. The issue was that, I was expecting the "x-amz-target" header to have a friendly name e.g "translate" but from this link, the "x-amz-target" header needs to be "AWSShineFrontendService_20170701.TranslateText"

Solution:

1. In postman, I created a new POST request.

2. I then changed the URL specific to an AWS Translate region from:

   https://translate.us-east-1.amazonaws.com/TranslateText
   

to :

    https://translate.us-east-1.amazonaws.com/

3. Under "Headers" I added the following headers:

   Content-Type: application/x-amz-json-1.1
   X-Amz-Target: AWSShineFrontendService_20170701.TranslateText

4. Under "Body", I selected "raw", and added the following sample body:

   {
     "SourceLanguageCode": "en",
     "TargetLanguageCode": "fr",
     "Text": "Creating a test terminology in AWS Translate"
   }
   

After testing again I got it working, as you can see in the screenshot below :
