Newsletter - API

Newsletter – API provides a REST interface for linking the Newsletter plugin with external platforms such as CRMs, e-commerce stores, and marketing automation tools. It lets developers manage mailing list subscribers programmatically, including adding, updating, and removing subscriber records. This can help sites keep newsletter data in sync with other systems that manage customer or contact information.

The interface supports subscriber status updates, private lists, and profile fields, giving integrations control over more than basic contact details. Server-to-server authentication uses API keys, with public access restricted to authorized systems. The API also supports autoresponder add-ons, so integrations can trigger email sequences when subscribers join specific lists.

Features
