You can create an SMS template while creating an Event with SMS enabled. You can easily create/update the template content by editing the event. Sample SMS Template An SMS message is a simple plain text message. The character limit for a single SMS message is 160 characters. When you send a SMS message over 160 characters, the message will be split into segments of 153. For example, a 161-character message will be sent as two messages, one with 153 characters and the second with 8 characters. The recipient’s device will then rebuild the messages and show as one. If you include non-GSM characters, such as (Hindi, Greek, Korean or Arabic etc), in SMS messages, Raven will send those messages with Unicode encoding. Such messages are limited to 70 characters and > 70 characters will be concatenated into 67 character message segments.
For SMS sent in India, the templates need to be registered on any of the DLT platforms. You should add the registered DLT Template ID in the SMS template.

​
Dynamic Content

To pass dynamic or custom data in the SMS template like invoice number, user name, tracking link etc., you should wrap it within handlebars . Raven uses Handlebars.js to parse the template and all handlebar operations are supported. Following Handlebars expressions are supported within templates:
  1. Nested objects
  2. #if, #each, #with
You will need to pass the value of the variables in the data object of Send Event API. Example SMS Template:

Additional fields

Apart from the SMS text, you can also send additional fields in the template. This is useful if you want to override the “From”/“Sender ID”/“Header” that you configured while setting up the integration.
This is how you can pass it in the Send Event API. Check the API doc for the complete request.
