I've been using RingCentral's SMS API in a sandbox environment for quite some time.
After my app was graduated to production by RingCentral I got new credentials and created a new JWT that's connected to my production app. (I login using the JWT on API requests).
1. Was able to create a webhook subscription
2. Not able to send an SMS using the API
I've read all of the threads in this forum but none of it is helpful.
Can someone please help me debug the issue and tell me what I'm doing wrong?
