I went through all the auth mechanisms and selected password authentication for my basic usage. But it can't seem to work although i have tried my best.
on this page, https://developers.ringcentral.com/guide/authentication/password-flow, it is noted:
Accept: application/json Content-Type: application/x-www-form-urlencoded Authorization: Basic cmVsLWFsbC1wZXJtaXNzaWXFjMmpRZmlQcnlkSUkweE92QQ== grant_type=password&username=18559100010&extension=101&password=121212
Can anyone explain are these request headers or request parameters? I'm myself confused and documentation pages seem to be scattered? Is the value in Authorization key is base64 encoded clientid and client secret or the username password combination? Any help would be appreciated.
