Using Postman to get access token with no user
I'm trying to follow the guidance in this do https://support.panopto.com/s/article/How-to-Get-OAuth2-Access-Tokens-for-Users to get an access token using my client secret and key using postman.
I post to https://<myserver>/Panopto/oauth2/connect/token using autherization type Basic Auth in the authorization tab and leaving username and password blank.
In the headers tab I added
Value: <ClientAPIKey>:<ClientSecretValue> (base 64 encoded with utf-8)
the result i get is
any idea where i am going wrong?
