One shortcode can choose otherwise: `[swissai_call mode="chat"]`. * One agent per language: a WebRTC client for each language, the button and the chat use the language of the page (works with Polylang and WPML). * Shortcode `[swissai_call]` to place the buttons in any page or post, `[swissai_call lang="de"]` to force a language. * Optional floating buttons on every page. * Button texts can be changed in the settings or per shortcode: `[swissai_call label="Talk to us" hangup="End call" chat_label="Write to us"]`. * The secret key stays on your server and never reaches the browser. **A SwissAI account is required.** The button and the chat talk to an agent that you create in the SwissAI dashboard: [create your account on swissai.dev](https://www.swissai.dev/login.html?signup=1). The settings page is translated into Italian, German, French, Spanish, Russian, Portuguese and Chinese; the buttons, the chat and their messages speak the language of the page. ### External services This plugin connects to SwissAI (developers.swissai.dev), a service of Swissvoip SA, to let visitors talk or write to your agent. * **Call**: when a visitor clicks the call button, your server sends the client name and the secret key you saved in the settings to `https://developers.swissai. dev/api/webrtc/token` and receives a temporary password valid for one call. On pages that show the call button, the browser loads `https://developers.swissai. dev/js/call.js`, which opens the call (audio from the visitor’s microphone) to the SwissAI switchboard. * **Chat**: when a visitor sends a message, your server sends to `https://developers. swissai.dev/api/messages` the client name and the secret key, the text of the message, the last exchanges of the conversation (at most 20) and a random identifier of the browser session, and receives the agent’s reply. The conversation is kept in the visitor’s browser only for the session; the plugin stores nothing on your server. No data is sent until the buttons are on a page; no call is started and no message is sent until the visitor clicks or writes. Terms of service: https://www.swissai.dev/terms.html Privacy policy: https://www. swissai.dev/privacy.html ## Installation 1. Create a SwissAI account on [swissai.dev](https://www.swissai.dev/login.html?signup=1): the button and the chat talk to a SwissAI agent and do not work without one. 2. In the SwissAI dashboard create an agent for each language of your site: its instructions, its knowledge base and, if you want, the tools it uses to book or look things up. 3. In the dashboard open Telephony › WebRTC clients, create one client per agent and add your site’s domain. Copy the client name (`wc_…`) and the secret key (`wk_…`): the key is shown only once. The same client is used by the call and by the chat. 4. In WordPress install and activate the plugin, then open Settings › SwissAI Click to Call and paste each client name and secret key in the row of its language; mark one as default. 5. Choose what to show on the site: Call, Chat or Both. 6. Add the shortcode `[swissai_call]` to a page, or enable the floating button. For the call the site must use HTTPS: browsers allow the microphone only there. ## FAQ ### Do I need a SwissAI account? Yes. You create the agent and the WebRTC client in the SwissAI dashboard. ### Do I need a different key for the chat? No. The chat uses the same client name and secret key as the call, and the same agent answers. ### Can I show only the chat? Yes. In the settings choose Chat; or use `[swissai_call mode="chat"]` on a single page while the rest of the site keeps the call. ### Are calls and messages billed? Calls from the button count as minutes on your SwissAI plan, like any other call. Chat messages follow the conditions of your SwissAI plan. ### The button does not start the call Check that your site’s domain is listed in the WebRTC client in the SwissAI dashboard and that the site is served over HTTPS (browsers require it for the microphone). ### The chat says it is not available The SwissAI account behind the client has no active trial or plan, or no credit: check Billing in the SwissAI dashboard. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “SwissAI Click to Call” is open source software.
