Invalid Cross-Origin Request when trying to retrieve Session Key

vmalla - Can you try to hit Get request and passing the user.login and password on URL? 

/vc/authentication/sessions/login?user.login=login&user.password=pwd

Hi,

Thanks for quick reply.

I've tried as you suggested. I'm getting below error.

<response status="error">
<error code="302">
<message>
User authentication failed.
</message>
</error>
</response>

Below is postman collection file. Save this file as .json and import it on POSTMAN tool.  After importing the file just update the URL and credentials.

	"info": {
		"name": "DEMO TEST",
		"_postman_id": "e2e70e34-333c-7fd3-59a1-9489427af7de",

	},

Hi TariqHussain,

I'm still getting the same response !!

302 if I use get and 'Invalid Cross-Origin Request.' if I use post method.

vmalla - Please confirm your username and password. It's your credential issue. 

Same happens if you just enter the GET url into the browser address field and request it without the Postman extension?

Yes, If I use get request then I'm getting 302 error.

I'm able to get session key if I'm logged into my instance and turn on the interceptor in Postman. If I'm not logged into community or if I turn off my interceptor, I'm getting '302 User Authentication Failed' error.
