Unable to obtain Microsoft Graph OAuth access token

I'm following this documentation to get an access token to call Graph APIs for Outlook Calendar. I've registered my app on Azure AD admin center, created a client secret and exposed relevant APIs. The app is configured for multi-tenant access and I'm using OAuth v2.0 endpoints for authorization.

I can successfully get the authorization code but get this error when requesting an access token:

"error": "invalid_client",

"error_description": "AADSTS7000215: Invalid client secret is provided.",

"error_codes": [

    7000215

],

I send urlencoded client secret with the access token request, as mentioned here

Could you show how you are acquiring the token? - juunas
@juunas Here is the url: login.microsoftonline.com/organizations/oauth2/v2.0/… - Shubhankar
And what does the request for the access token look like? - juunas
Did you have a try with creating a new client secret? And please provide your request for the access token. - Allen Wu

You provided an invalid client secret.

Just copy it from Azure AD app and paste it into your request. There is no need to url encode it.
