SMS API for sending text to customers
Tags: getting started

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?

Yes, very much possible... you can send messages to your customers as well and you can monitor those messages using API providing message id & attachment id as well as using subscription

You can easily use Subscriptions or Webhooks with Push Notifications to monitor inbound SMS. In fact, there is an "Instant Filter" type of 'SMS' which can be used so you can create an event consumer which only handles inbound (or outbound) SMS.

Awesome, thanks for the fast reply ... yes, I noticed in the docs that RingCentral lets you send 30 SMS/minute ... so about 1 every other second or there about.

So, you just used the REST/JSON API to send the SMS?

Also, what about in-bound SMS from customers - anyone do that?

I've already done this and it works fine. My application was to send an SMS to employee's personal number when there is an active Evacuation/Alarm. At the time, i have to time it to 1 SMS per second or the system will reject the task - This might have been fix, but not sure.
