Sending SMS from n8n with Hardcoded Authorization Token

Yes it is possible by using a JWT token. Please read this dev guide article to learn more about it.

Thanks, from what I understand, I’ll have to use the JWT to get an access token, rigtht?

> How does JWT authentication work?

• Each user needs to login the RingCentral developer portal to generate their own JWT token. Particularly for sending or accessing SMS message store, only the user who owns the JWT token, can be authenticated by your app to send SMS from their number.

> JWT authentication and password-based authentication modes are almost identical. They both are a standards-compliant OAuth flow for which developers will perform the following steps:

• We no longer support password flow

> The developer presents a JSON Web Token to the platform.

• That is the user JWT

> The platform responds with an access token.

• Once you have the JWT token, you call the /token endpoint to get the access token and the refresh token (if set at the app settings). An access token is valid for 1 hour and a refresh token is valid for 7 days. You can use the refresh token to get a new access token, and every time you refresh the token, you will get a new refresh token which again is valid for another 7 days.

> The developer utilizes the access token in subsequent requests to the API. >

• Correct

I was expecting something simpler
