Annovisio

AnnoVisio turns Calendly into a clear annual event calendar for WordPress.

Calendly is excellent for booking, but not for showing many events clearly across a whole year. AnnoVisio solves this by importing your Calendly event types and displaying them in a compact annual calendar on your WordPress site.

Ideal for:

• Training providers
• Retreat organizers
• Workshop and seminar hosts
• Schools and clubs
• Venues and event spaces

Key features:

• Import and sync Calendly event types
• Display events in a clear annual calendar via shortcode
• Support multi-day events
• Let visitors open the Calendly booking flow directly from the calendar
• Run manual syncs or optional automatic synchronization via WP-Cron

AnnoVisio is built for site owners who want to present bookable events in a much clearer way than with a standard Calendly embed.

External services

This plugin uses Calendly as an external service. Calendly is required to synchronize Calendly event types into WordPress, to check availability before opening a booking dialog, and to display Calendly’s booking popup on frontend pages that use the [annovisio] shortcode.

External services used:

• Calendly service: https://calendly.com
• Calendly API endpoint used by the plugin: https://api.calendly.com
• Calendly frontend widget assets loaded by the shortcode: https://calendly.com/assets/external/widget.js and https://calendly.com/assets/external/widget.css

What is sent to Calendly and when:

• During manual synchronization and WP-Cron automatic synchronization, the plugin sends authenticated server-side GET requests to https://api.calendly.com using the Calendly Personal Access Token configured by the site administrator in the WordPress admin area.
• During synchronization, the plugin requests Calendly data from /users/me and /event_types. For availability checks, the plugin requests /event_type_available_times. Request parameters can include Calendly user URI, event type URI, active, count, start/end time values, and Calendly pagination URLs returned by previous API responses.
• When a site visitor clicks an event rendered by the [annovisio] shortcode, the visitor’s browser first calls this plugin’s WordPress REST endpoint on the same WordPress site with the Calendly event type URI and either a selected date or a UTC slot start. The plugin then sends a server-side authenticated request to Calendly’s /event_type_available_times endpoint with the event type URI and the calculated start/end time window.
• On frontend pages where the [annovisio] shortcode renders the calendar, the visitor’s browser loads Calendly’s widget JavaScript and CSS from calendly.com so Calendly’s booking popup can be displayed. Interactions inside the Calendly booking popup are handled by Calendly.
