I am new to the RingCentral developer API so forgive me if this is too basic.
I want to use the RingCentral API to sent out-bound SMS to my customers. Rather than use (and pay for) a 3rd party like Twilio, I am already a RingCentral customer.
In the docs, the examples are all of sending text messages within my company via RingCentral.
BUT, I need to send TXT from my company number to my customers.
Can I use the RingCentral API web service to sent SMS to customers - or - am I limited to only inside my company?
Thanks!
