Using Postman with the API

As part of our new API developer engagement, we created a Postman collection to share, sync and collaborate with developers using our API.

What is Postman?

Postman is a tool that helps generate and test API calls by providing a clean interface to build and save HTTP requests, and to check and test the API responses. To get started with Postman, download the native application here.

Envizage created a set of basic starter workflows which can be used to get started with the API.


Create a developer account in the Developer Console

Step 1: Download the Envizage Basic Workflow

Step 2: Configure The Postman Environment

Before sending a request from the API, a Postman Environment needs to be created, which is a way to store and use variables between your API calls.

To create a new Environment in Postman, click New and select Environment, enter a name (eg. Envizage).

Postman start

Now add the following environment variables:

Postman credentials






Realm, clientId and clientSecret are generated in Developer console after connecting a back-end application and can be found in Applications page.

Postman show

Environments can be managed by clicking the gear button in the top right corner of the app.

Step 3: Import the workflow and implement the client credentials flow

Click the Import button in the top left corner (next to New) and select or drag and drop the downloaded JSON file.

Postman import

Once the Workflow is imported, it should appear in the left hand side menu.

Postman imported

Expand “envizage [client credentials flow]” and select the first request named "1. token". Make sure that the Envizage environment is selected in the top right corner, and click “Send”.

If the call was successful, then the result will be returned and displayed in the bottom half of the screen and the resulting access token is saved in the environment, so the next call can be made. Service account

The snippet which saves the service access token can be found under Tests in the request bar.

Set variable

This snippet extracts the access token from the result body of the request, and saves it under the variable name “serviceAccessToken”. This value now can be used in subsequent calls (within the Envizage environment) by surrounding the variable names with curly braces.


The latest version of Postman has dedicated Authorization mechanisms and you are no longer required to manually set the header. However, in the code you will still need to.

Use the serviceAccessToken obtained from the previous step in order to create a new user. Create user

Pass user's mandatory data such as username, password and email in request's body. In case you set emailVerified property to false, two more requests are needed in order to update this value to true. In the following example, emailVerified has been set to false, thus the next two requests with number 3 and 4 are used to update this value. Create user

The last step before start using the Envizage APIs is to obtain the user access token. To do that, you have to execute the fifth request named "5. user token". Env check

The snippet below extracts the access token from the result body of the request, and saves it under the variable name “accessToken”. This variable should be used in the Authorization header of every request that communicates with Envizage API. Create user

Step 4: Make a first call to retrieve all scenarios

Following the client credentials flow as described in step 3 and having the user access token, you can start using the Envizage API. By successfully executing the sixth request, you can retrieve all scenarios. Get scenarios

Each end-point is documented individually in the API Reference section.
