It is clear that you have not authenticate your app to access the platform.

Read these documentation to learn how to create and app, authenticate and call the APIs

https://developers.ringcentral.com/guide/applications https://developers.ringcentral.com/guide/authentication https://developers.ringcentral.com/guide/messaging/fax/sending-faxes

Ask in a different thread if and when you have a particular question.

@Phong Vu It appears I have authorized it. However, I receive what you will see below when attempting to use the callback URI: https://app.workato.com/oauth/callback

"Workato OAuth authorization failed Unknown/invalid shared account with id ="

What is your app client id? How do you call the /authorize to authenticate?

Provide some code snippet w/o sensitive information.
