Getting 415 - Unsupported Media Type in Postman post method

Question

I have using postman (https://www.getpostman.com/) for testing my APIs APIs are in AWS ApiGateway and Lambda function (NodeJS)

(1) When first time I am sending post method request to server, it's giving proper response, I am not sending any post params for now.

Here is request header-

Connection →keep-alive
Content-Length →61
Content-Type →application/json
Date →Fri, 24 Mar 2017 09:09:13 GMT
Via →1.1 440f7503597ca64245c4258c03b08e0c.cloudfront.net (CloudFront)
X-Amz-Cf-Id →t50_SeWgC3Qb2ZFtf4fksUTdi5viINCaAEj8MPTvhRbtMHu-LK1mwA==
X-Amzn-Trace-Id →Root=1-58d4e239-76404c1ab9912d010fac33a2
X-Cache →Miss from cloudfront
x-amzn-RequestId →8c8f9bd2-1071-11e7-9490-79b68cde95e0

Here is response

{
  "response": "false",
  "message": "Please enter a valid email !"
}

Its working fine when no post params send to request.

(2) And now when I am sending some params to request , The request header changed and its removed one header prama X-Amzn-Trace-Id

Here is request header-

Connection →keep-alive
Content-Length →37
Content-Type →application/json
Date →Fri, 24 Mar 2017 09:02:52 GMT

X-Cache →Error from cloudfront
x-amzn-RequestId →a9c4116a-1070-11e7-b08c-c3cf73411cde

Here is request body

{
"userEmail":"[email protected]",
"userPasswod":"123456",
"userName":"rahul"
}

Here is response

{
  "message": "Unsupported Media Type"
}

After lot of R&D I have also added content/Type- application/json in header but still getting same response.

Please somebody help me to figure out this issue with postman.

Solution

I was having a similar experience using postman and aws. I could get the appropriate response testing within AWS but when I tested within postman I'd get "Unsupported Media Type" I solved it in postman by selecting the Body tab, then selecting the raw radio button, then selecting JSON(application/json) in the dropdown. Finally I filled in the raw data similar to what my test data in AWS looked like. It looked something like this:

I hope that helps, good luck!
