No data is sent to Cardee Technologies or any other third party. See the Privacy Policy section below for details. ### Privacy Policy This plugin connects to the Sappien server URL that the site administrator configures in the plugin settings. **Data transmitted to the configured Sappien server:** * For logged-in users (when Secret Key is set): user ID, display name, email address, and HMAC-SHA256 signature. * Documents uploaded by the administrator. * Custom instructions entered by the administrator. * Chat messages entered by site visitors. **This plugin does not transmit any data to Cardee Technologies or any server other than the Sappien instance you configure.** For privacy details specific to your Sappien instance, consult your Sappien provider. ## Screenshots * [[ * Configuration tab — connection, display mode, widget appearance, and visibility settings. * [[ * Documents tab — upload and manage files for the agent knowledge base. * [[ * Instructions tab — custom agent prompt instructions with character counter. ## Installation 1. Download the plugin from the WordPress Plugin Directory. 2. Upload the `sappien-connector` folder to `/wp-content/plugins/`. 3. Activate the plugin from the **Plugins** screen in WordPress. 4. Go to **Sappien** in the admin menu (or **Settings > Sappien Connector**) and enter your Server URL and API Key. Alternatively, search for “Sappien Connector” directly in **Plugins > Add New** and click **Install Now**. ## FAQ ### Do I need a Sappien account? Yes. You need an active Sappien instance with an API Key. Contact your Sappien provider for credentials. ### Is the Secret Key secure? Yes. The Secret Key is used on the server to sign the user identity payload (HMAC- SHA256). It is never exposed to the browser or included in any frontend output. ### Can I use multiple agents on the same site? Yes. Use the shortcode with per-instance credentials: `[sappien_chat key="ck_agent2" secret="sk_secret2"]` ### Which file formats can I upload? PDF, DOCX (Word), TXT, and Markdown (MD). Maximum size: 20 MB per file. ### How do I hide the widget on certain pages? In the **Configuration** tab, enter comma-separated page slugs in the **Exclude pages** field (e.g. `checkout, cart, my-account`). ### How does automatic user identification work? With a Secret Key configured, logged-in WordPress users are identified in the chat automatically. Their user ID, display name, and email are signed with HMAC-SHA256 and sent to Sappien so the agent can greet them by name. ### What happens when I update from a previous version? Settings are migrated automatically. No data is lost. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Sappien Connector” is open source software.
