Authenticating to CRM API without login screen, NodeJs

Posted on by Community Member

I'm able to use postman to fetch data from the CRM api, but it requires a login screen to pop up. Is there a way that I can include my email/password in the headers in order for me to obtain the authorization token?

    I haven't figured out a way to remove the log in screen from Postman, but I can when I make a node application. Using the adal-node library, you can acquire an access token via the acquireTokenWithUsernamePassword function. See this url for the documentation: https://www.npmjs.com/package/adal-node. My code example is below.

    var AuthenticationContext = require('adal-node').AuthenticationContext;
var clientId = "{{Your clientId here}}"; // Application Id of app registered under AAD.
var resource = 'https://{{crmUrl}}.crm.dynamics.com/'; // URI that identifies the resource for which the token is valid.

//The url used to login. Common is a general url for microsoft logins
var authorityHostUrl = 'https://login.windows.net';
var tenant = `common`; // AAD Tenant name.
var authorityUrl = authorityHostUrl + '/' + tenant;

var username = '{{Your email here}}';
var password = '{{Your password here}}';

var context = new AuthenticationContext(authorityUrl, false);

context.acquireTokenWithUsernamePassword(resource, username, password, clientId, function(err, tokenResponse) {
	if (err) {
		console.log('well that didn\'t work: ' + err.stack);
	 } else {
		console.log(tokenResponse);
	 }
});
