Start accepting appointments instantly ### Perfect for appointment-based businesses The free booking plugin works for cleaning services, auto detailing, law firms, real estate agents, landscapers, beauty professionals and stylists, therapists, fitness coaches and personal trainers, photographers, pet groomers, tutors, music teachers, life and business coaches, consultants, accountants and bookkeepers, and mobile service providers — any appointment-based business that wants a clean Google Calendar booking experience. ### Why choose this plugin * Free Google Calendar appointment booking, no time limit * Real-time availability — no double-bookings * Add a booking button anywhere on your site * Simple booking calendar — most users are live in under 5 minutes * Client-friendly booking experience on any device * Multiple appointment types and customizable availability * Optional add-on plugins available from smsreminder.app for SMS appointment reminders and additional Google Calendars ### External Services This plugin connects to the SMS Reminder service to enable booking functionality and SMS notifications. ### Service details * Service: SMS Reminder * Marketing website & support context: https://www.smsreminder.app/ * Booking web app (login / OAuth): https://www.smsreminder.co/ * API base URL: https://go-interactive.herokuapp.com/ ### What data is sent and when The plugin communicates with the SMS Reminder API in the following cases: * **On connection (administrator-initiated):** - Site URL - Callback URL - Platform instance identifier - Temporary authentication state * **After connection, in WordPress Admin (administrator-initiated):** - Authenticated API requests (using the stored access token) to fetch booking configuration, upcoming appointments and related customer fields shown on this plugin’s settings screen, and other data needed for setup and previews. * **On the public site when the booking block is present:** - Each page view that renders the block can trigger a server-side request to retrieve embed parts for the booking button. Site visitors do not need to click the button for that request to occur. Only the administrator starts connection and plugin setup. After the site is connected, normal page loads, not only explicit clicks in the dashboard, can cause your server to contact the SMS Reminder API when booking content is embedded on a page. **Site administrators:** Information on the **Settings SMSReminder Booking** (for example customer name, phone, or message on upcoming appointments) is loaded from your SMS Reminder account over the API for display in WordPress Admin. Treat it as remote data governed by SMS Reminder’s policies, not as data this plugin independently collects from site visitors. ### Why this is needed This communication is required to: – Link your WordPress site to your SMS Reminder account – Generate booking interfaces – Enable automated SMS reminders and confirmations ### Terms and privacy * Privacy Policy: https://www.smsreminder.app/privacy-policy * Terms of Service: https://www.smsreminder.app/terms-of-service ## Blocks This plugin provides 1 block. * SMS Reminder Booking Button Insert a button that takes clients to your booking page. ## Installation 1. Install and activate the plugin. 2. Connect your Google Calendar. 3. Set your appointment availability and appointment types. 4. Add your booking page or booking button to your site. 5.
