"errors" : [ {

"errorCode" : "OAU-140",

"message" : "Invalid resource owner credentials"

} ],

"error_description" : "Invalid resource owner credentials"

Please read this article. Summary, you cannot send SMS on behalf of other extensions. The number must belong to the extension who currently login your app, and the number must have the SmsSender feature.

In your case, I guess that you are using the company number from an extension which is not assigned with the SmsSender feature. Check the sample code from the quick start link below to see how to detect SMS feature before using the number.

Clearly you logged in with wrong user credentials. Use the one that you can use to login service.ringcentral.com

ok, i changed the extension from 101 to 100, and passed the authorization, but got another strange error:

{

"errorCode" : "FeatureNotAvailable",

"message" : "The requested feature is not available",

"errors" : [ {

"errorCode" : "MSG-242",

"message" : "The requested feature is not available"

} ]

}
