What an iTeam agent does with the Calendly API
Briefing before the meeting
When a booking arrives, the agent looks up the company in the CRM, adds history and the form answers, and sends the salesperson a briefing.
The right link in the conversation
During qualification on WhatsApp, the agent creates a single-use link to the responsible salesperson's calendar.
Cancellation with rescheduling
When someone cancels, the agent offers new times and tells the calendar owner.
No-shows handled
After meetings where the invitee did not show, the agent sends a rescheduling message and logs it in the CRM.
From the credential to the agent at work, with approval
Generate the token or authorize the app
Create a personal token for an admin user or authorize the OAuth app for the organization.
Store it in the iTeam vault
The token stays in the vault. You define which calendars the agent can use and who it sends links to.
Turn on the webhook and test
Set up the booking webhook, make test bookings and check the briefing generated.
