Postman Echo call giving NULL result

[satellite-pilot-1122 (Raghav Chandak)]

Hi All,

I have been using the API call to parse a JSON using https://postman-echo.com/post; in the body I am adding my JSON file but the response I am getting is NULL as shown below

{
“args”: {},
“data”: {},
“files”: {},
“form”: {},
“headers”: {
“x-forwarded-proto”: “https”,
“x-forwarded-port”: “443”,

Hey @satellite-pilot-1122

Welcome to the Postman community

You’re missing the details about the request body that you have used.

I don’t what should be there without that information.

Have you tried the same with a new request using a different HTTP method?

Hi Danny,

the request body has JSON file which is about 14Mb big

Not really understanding what your workflow is here and the need to essentially echo all that back in the response.

Does it work with a reduced amount? Is it the same when everything you add there?

So basically i have a server from which I am making GET calls. But due to limit on the server the response back is only 1000 lines. Therefore I need to make multiple API calls to get the full response back.
Then I need to stick all response back into 1 JSON file and then perform the Postman Visualise.

For making multiple API calls and sticking all data into 1 JSON I have written a different Python code which is working fine. Once I have the combined JSON file I am trying to parse in into Postman Echo to have a Visualise of that and that’s where I am facing challenge.

Yes with less data it works fine. Is there a hard limit on Postman Echo ?
