Manage environment

Representational state transfer (REST) or RESTful Web services are one way of providing interoperability between computer systems on the Internet.
Postman can help with your Restful API development.

To set up the environment your API uses, refer to this document.https://www.getpostman.com/docs/environments

Set env parameter from response

GET request to get response body

This request returns a JSON body with a session token. For this dummy API, the token is needed for a successful POST request on the ‘/status’ endpoint. To extract the token, we need the following code.

var jsonData = JSON.parse(responseBody); postman.setEnvironmentVariable(“token”, jsonData.token);

var jsonData = JSON.parse(responseBody);
postman.setEnvironmentVariable("token", jsonData.token);

Add this to the test editor and hit send. Hover over the quick look window (q) to check that the variable “token” has the value extracted from the response. http://blog.getpostman.com/2014/01/27/extracting-data-from-responses-and-chaining-requests/

Loop over response data and execute another request <a name=loopResponse></a>

General idea is explained here, but differ carefully postman.setNextRequest(‘saved post request title’) and pm.sendRequest().
The later one execute request but the former one only modify the request therefore not useful alone in the loop.

var jsonData = JSON.parse(responseBody);

jsonData.resources.forEach(function(resource) {
    
    postman.setEnvironmentVariable("request_id", resource.metadata.guid);

    pm.sendRequest({
        url: 'https://' + pm.environment.get("sec_request_url") + '/' + resource.metadata.guid + '/revoke',
