Acquire Token using Postman and Grant Type - Password¶
This document describes the steps to obtain and use OAuth 2.0 access tokens using Postman.
Overview of Grant Type – Password¶
The Password grant is used when the application presents a traditional username and password login form to collect the user’s credentials and makes a POST request to the server to exchange the password for an access token. The POST requests that the application made looks like the example below.
Form the Post Request¶
The POST Request method requests that a web server accepts the data enclosed in the body of the request message, most likely for storing it
| Title | URL |
|---|---|
| POST | http://hostname:port/oauth/token?grant_type=password&username=<username>&password=<password> |
Update the username and password in URL and use as request header.
Click on Authorization tab and select Type - Basic Auth¶
Basic Auth is an authorization type that requires a verified username and password to access a data resource.
Use default Username sparkflows and Password secret for client authentication. Click on Send to authorize the user and get the access token.
Example¶
Now use access_token from previous step to access the REST API¶
An Access Token is a credential that can be used by an application to access an API. Below is an example to invoke the nodeList REST API of Fire Insights.
