Error getting access_token with "Bad Request - Invalid URL HTTP Error 400" on Microsoft authentication endpoint

Question

I am trying to retrieve the access_token and refresh_token from the Microsoft authentication endpoint using Postman. However, I am getting the following error message:

Hi @Ibn Ishaq

Thank you for posting this in Microsoft Q&A.

I understand you are trying to retrieve the access_token and refresh_token from the Microsoft authentication endpoint using Postman but getting error HTTP Error 400-The request URL is invalid.According to the screenshot you provided, it appears that you have included the content-type in the URL. You should place the content-type parameter in the header section.

Request an JWT access token using the Postman

Set method as POST.
URL: https://login.microsoftonline.com/consumers/oauth2/v2.0/token
Headers -> Content-Type: application/x-www-form-urlencoded
client_id= Application_id
scope=user.read
code= {The code acquired in previous step}
redirect_uri= https://localhost
grant_type=authorization_code

Hope this helps. Do let us know if you any further queries.

Thanks,
