Postman extension setting an environment variable from response headers or body

Question

Postman extension had a feature of setting an environment variable from one of the values from response headers or body. It is missing after update. Can someone help here.

Answer 1

You can set the environment variable from response body/header as follows:

From Response Body:

var body = JSON.parse(responseBody);

postman.setEnvironmentVariable("[environmentVariable]", body.variableName);

From Response Header:

var headerName = responseHeaders.headerName;

postman.setEnvironmentVariable("[environmentVariable]", headerName);

Answer 2

For Postman extension on Chrome latest version (by posting time) version 4.8.3 here.

Everthing is working fine regarding setting an environment variable programatically in either Pre-request script section or Tests section.

For more info, check docs here.

Answer 3

This is an old question, I'll leave this here as an update:

to set a variable from response body ( JSON ):

var jsonData = JSON.parse(responseBody);
pm.environement.set("your_var", jsonData["the_value"]);

and to get it from a header:

var value = pm.response.headers.get("the_header");
pm.environement.set("your_var", value);
