-# CiviCRM WP REST API Wrapper
-
-This is a WordPress plugin that aims to expose CiviCRM's [extern](https://github.com/civicrm/civicrm-core/tree/master/extern) scripts as WordPress REST endpoints.
-
-This plugin requires:
-
--   PHP 7.1+
--   WordPress 4.7+
--   CiviCRM to be installed and activated.
-
-### Endpoints
-
-1. `civicrm/v3/rest` - a wrapper around `civicrm_api3()`
-
-    **Parameters**:
-
-    - `key` - **required**, the site key
-    - `api_key` - **required**, the contact api key
-    - `entity` - **required**, the API entity
-    - `action` - **required**, the API action
-    - `json` - **optional**, json formatted string with the API parameters/argumets, or `1` as in `json=1`
-
-    By default all calls to `civicrm/v3/rest` return XML formatted results, to get `json` formatted result pass `json=1` or a json formatted string with the API parameters, like in the example 2 below.
-
-    **Examples**:
-
-    1. `https://example.com/wp-json/civicrm/v3/rest?entity=Contact&action=get&key=<site_key>&api_key=<api_key>&group=Administrators`
-
-    2. `https://example.com/wp-json/civicrm/v3/rest?entity=Contact&action=get&key=<site_key>&api_key=<api_key>&json={"group": "Administrators"}`
-
-2. `civicrm/v3/url` - a substition for `civicrm/extern/url.php` mailing tracking
-
-3. `civicrm/v3/open` - a substition for `civicrm/extern/open.php` mailing tracking
-
-4. `civicrm/v3/authorizeIPN` - a substition for `civicrm/extern/authorizeIPN.php` (for testing Authorize.net as per [docs](https://docs.civicrm.org/sysadmin/en/latest/setup/payment-processors/authorize-net/#shell-script-testing-method))
-
-    **_Note_**: this endpoint has **not been tested**
-
-5. `civicrm/v3/ipn` - a substition for `civicrm/extern/ipn.php` (for PayPal Standard and Pro live transactions)
-
-    **_Note_**: this endpoint has **not been tested**
-
-6. `civicrm/v3/cxn` - a substition for `civicrm/extern/cxn.php`
-
-7. `civicrm/v3/pxIPN` - a substition for `civicrm/extern/pxIPN.php`
-
-    **_Note_**: this endpoint has **not been tested**
-
-8. `civicrm/v3/widget` - a substition for `civicrm/extern/widget.php`
-
-9. `civicrm/v3/soap` - a substition for `civicrm/extern/soap.php`
-
-    **_Note_**: this endpoint has **not been tested**
-
-### Settings
-
-Set the `CIVICRM_WP_REST_REPLACE_MAILING_TRACKING` constant to `true` to replace mailing url and open tracking calls with their counterpart REST endpoints, `civicrm/v3/url` and `civicrm/v3/open`.
-
-_Note: use this setting with caution, it may affect performance on large mailings, see `CiviCRM_WP_REST\Civi\Mailing_Hooks` class._
