## Description

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.

## Installation

 1. Upload the plugin files to `/wp-content/plugins/cleverconnected-subscriber-sync-
    mailpoet`, or install the ZIP through Plugins > Add New > Upload Plugin.
 2. Activate CleverConnected Subscriber Sync for MailPoet and make sure MailPoet is
    active.
 3. Go to Users > Profile and create a WordPress Application Password for an Administrator
    account.
 4. Enter that username and Application Password in CleverConnected.
 5. Optionally go to Settings > CleverConnected for MailPoet and enter the CleverConnected
    callback URL and a callback signing secret.
