Arengu Auth Wordpress plugin

This module enables custom signup, login and passwordless endpoints to interact with WordPress's authentication system from Arengu flows.

Installation

  2. Activate the plugin through the "Plugins" menu in WordPress.
  3. Go to "Arengu" menu to see the info you need to connect a flow to WordPress.

Available endpoints

Private endpoints

The private part of the API is protected by an API key. You can view and manage your API key under your plugin settings, in the WordPress admin panel.

Warning: This API key allows to impersonate any user in your blog, so you must keep it secret and do not share it in publicly accessible areas such as GitHub, client-side code, and so forth.

Authentication to the API is performed via Authorization header with Bearer schema:

Authorization: Bearer YOUR_API_KEY

Sign up users with email and password or just with an email (passwordless signup).

POST /index.php?rest_route=/arengu_auth/signup
Content-Type: application/json

Place the following shortcode tag where you want your form to appear:

[arengu-form id="YOUR_FORM_ID"]

You have to replace YOUR_FORM_ID with your Form ID, which you can find in your form settings or share page.
