Get Subscription Preferences API

This API is used to get the subscription category preferences for a specific customer on your custom landing page.

API Endpoint

GET https://api-0X.moengage.com/v1/category-subscription/user-preferences

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

All Subscription Categories API requests will be authenticated through Basic Authentication.

To generate the Basic Authentication header:

Navigate to Settings > APIs > DATA API Settings
Copy the DATA API ID and DATA API KEY
Generate the Authentication Header String
Basic Authentication encodes a 'username:password' using base64 and prepends it with the string 'Basic '. To generate the Auth header:

- Add a colon after the user name (DATA API ID) and concatenate it with the password (DATA API KEY).
- Encode the concatenated string using base64 encoding.
- Pass the encoded string in the HTTP authorization header as follows: {"Authorization":" Basic bmF2ZWVua3VtYXI6bW9lbmdhZ2U=="}
