Smooch offers SMS through integration with Twilio.
Twilio is an SMS messaging service. Our Twilio integration allows your users to send you text messages at your Twilio number for your to receive in a business system or with Webhooks. Your replies are sent back as an SMS to the user.
You’ll need a Twilio account with a phone number configured on it. Once you’ve set up your Twilio account, obtain your API credentials from the Twilio account settings page. Then, select the phone number from the Twilio phone numbers page and enter the
SID and API credentials on the Smooch dashboard or via the REST API.
You should now be able to receive messages from your Twilio phone number and reply via any of your configured business system integrations.
