CleverConnected Subscriber Sync for MailPoet

CleverConnected Subscriber Sync for MailPoet adds a deliberately small, secure integration surface:

• an authenticated REST endpoint for creating or updating a MailPoet subscriber and assigning lists;
• signed outgoing callbacks for MailPoet subscriber create, update and delete events;
• a settings page under Settings > CleverConnected for MailPoet.

MailPoet must be installed and active. The plugin uses MailPoet’s documented PHP API and subscriber hooks; it does not access MailPoet database tables.

This plugin is developed by Ambition4Clients for use with the CleverConnected platform. It is not affiliated with, endorsed by, or sponsored by MailPoet or Automattic.

REST API

Authenticate with WordPress Application Passwords using HTTP Basic Auth.

POST /wp-json/cleverconnected-mailpoet/v1/subscriber

Send JSON such as:

{"email":"subscriber@example.com","first_name":"Ada","last_name":"Lovelace","lists":[4,5],"custom_fields":{"company":"Example Ltd"}}

The endpoint returns the MailPoet subscriber ID and email. Confirmation and welcome emails are not sent for API-originated updates.

Outgoing callbacks

When configured, the plugin sends JSON callbacks with type (subscriber.updated or subscriber.deleted), subscriber, and occurred_at. The X-CleverConnected-Signature header contains an HMAC SHA-256 signature of the exact request body, using the callback signing secret. Failed transient deliveries are retried once after five minutes.

Privacy

This plugin processes subscriber contact details only to send them between your WordPress site, MailPoet and the configured CleverConnected endpoint. It does not send data to the plugin author or any other service.
