For further Zinc customization, you can use the Messaging API and User Properties Import API.

The Messaging API allows you to programmatically send Zinc Messages to individual users or Groups. You can create automated systems that notify Zinc users or Groups at times when certain events occur. You can push information into Zinc from any system that can be configured to send HTTP requests that are triggered by specific events, or write custom code to send a Zinc Message based on unique business logic.

The User Properties Import API allows you to programmatically import a list of User Properties for your users.

Zinc API access is included with your subscription, and request volume is limited. If you need to use API calls beyond the standard allocation, limits can be increased for additional fees.
