Keep Calendly Contacts in sync across systems.
ICYMI: Calendly Contacts keeps relationship details, meeting history, and follow-ups in one place, automatically building and updating contact profiles as users schedule and meet.
Developers can now access and manage Contacts through the Public API and stay in sync with webhooks.

Use cases
Many teams use Calendly alongside CRMs, marketing platforms, support tools, workflow automation tools, and internal systems. Contacts APIs make it easier to keep Contact data synced across systems without relying only on scheduling events as the source of truth.
This also enables new workflows built around Contact events — including enrichment, automation, segmentation, and AI-powered experiences.
Some example use cases
- Sync Contacts between Calendly and marketing automation tools
- Trigger workflows when Contacts are created or updated
- Build internal tooling on top of Contact data
- Power AI assistants with contact and scheduling information
