Automation & workspaceUSEvery booked meeting lands in your CRM and calendar on its own
Calendly lets clients pick a time for a call or demo from your calendar without the back-and-forth. We connect Calendly to your CRM, mailing tools and messengers so a new booking, a cancellation or a reschedule shows up where your team actually works: a deal gets created, the manager is notified, and a reminder goes out to the client.
Before the manager copied the client's name and time from a Calendly email into the CRM by hand and sometimes forgot.
After the moment a client books a demo, a deal with the contact, the meeting time and the answers from the booking form appears in the CRM.
Before a client cancelled, but the deal stayed in the 'demo scheduled' stage and the manager prepared for a call that never happened.
After a cancellation moves the deal to a follow-up stage and posts a task; a reschedule simply updates the time.
Before the manager sent a presentation and a reminder to each client manually, an hour before the call.
After after a booking the client automatically receives a message in the messenger or by email with the agenda and materials, and the manager gets a summary of who is coming.
Before people filled in the qualification form, did not pick a time and disappeared without a trace.
After every submitted form creates a lead in the CRM even without a booking, and the sales team follows up with those who dropped off.
Before to count how many demos each manager held and how many were cancelled, someone opened every calendar by hand.
After all bookings and cancellations across the team flow into one table, and the report builds itself.
For those who want to check: each point links to the official documentation page it comes from.
Calendly API v2 delivers booking data through webhook subscriptions whenever invitees schedule, cancel or reschedule a meeting.

Source: developer.calendly.com ↗ checked 2026-09-28Automatic event notifications are available only on the Standard, Teams and Enterprise plans; on the basic plan the connection can read data but will not receive events on its own. Calendly limits the number of requests per user, so bulk reads are spread out in time. There is no way to reschedule a meeting from the outside — only cancel and reschedule links are available, which the client follows. If a receiving server stays down for a day, the subscription switches off and has to be re-created; we monitor this. An access key stops working when the account's login email, password or sign-in method changes.

A developer studies the brief, asks about anything unclear and sends an estimate.
Once scope and price are agreed, the work begins.
