Create SMS Template API

Beta Callout

This is a Beta Feature. To enable it, please reach out to your CSM or mail us at support@moenage.com.

The Create SMS Template API can be used to create an SMS template in MoEngage. This API helps you upload templates created outside the MoEngage ecosystem to MoEngage and use them for campaign creation.

API Endpoint

POST https://api-0X.moengage.com/v1.0/custom-templates/sms

Each customer is hosted on a different data center; you can find your data center number (value of X) by checking the data center and API endpoint mapping page.

Authentication

Basic authentication sends a Base64-encoded string containing a username and password for all API requests.

Do the following when you are using the API for the first-time authentication:

Navigate to Settings > APIs > TRANSACTION PUSH/REPORT Settings.
Click on the Click here to show APP Secret link to see the APP Secret key.
User name - APP ID Password - API SECRET

For example, basic Authentication encodes a 'username:password' using base64 encoding and prepends it with the string 'Basic '. The string is passed in the authorization header as follows:

{"Authorization":"Basic bmF2ZWVua3VtYXI6bW9lbmdhZ2U="}

Request Headers

Key	Required	Sample Values	Description
Content-Type	Required	{"Content-Type": "application/json"}	Set the Content-Type header to application/json.
Authorization	Required	{"Authorization": "Basic bmF2ZWVua3VtYXI6bW9lbmdhZ2U=="}	This is the authentication parameter for access control and needs to be passed along with the request. The APP ID and API SECRET need to be picked up from the TRANSACTION PUSH API Settings in MoEngage Dashboard, and a Basic Authorization header needs to be created and set in the header. Navigation: Settings -> API -> General Settings -> TRANSACTION PUSH/REPORT SETTINGS section. For more information, refer to Authentication.
