Connect Google Calendar, Outlook, or Apple Calendar from Company Settings, then Integrations. TextWork reads free and busy time from the calendars you connect and writes the booking onto them.
A meeting page is the link a guest opens to pick a time. Set the length, the hours, how far ahead they can book, whether the invite includes a Meet or Teams link, and whether each booking files a report.
A Send message action can drop that link into a text. A bracketed field such as [name] fills in from the report that sends it.
How to use it is in Schedule meetings.
