Transactional SMS REST API

Use this API to send an SMS message to contact(s) you specify by providing the SMS phone number or a lookup key. SMS messages will only be sent to contacts whose consent status in Acoustic Campaign is 'opted-in'. You can use this REST API with all Acoustic SMS partners, including mGage, Karix, Infobip, and Celmedia.

This API allows you to personalize the message using a database field or by specifying the personalization value in the API payload (inline personalization). Each call is limited to a maximum of 1,000 contacts but there is no limit on the number of times per day this API can be called.
