How to Fetch and Embed Scheduling Links from Calendly, Cal.com, and 19+ Platforms with a Unified API
October 19, 2025
Most SaaS products need to let users share booking links — whether that's for demos, interviews, onboarding calls, or support sessions. The challenge is every scheduling provider structures these links differently, with unique authentication models and APIs for Calendly, Cal.com, SavvyCal, HubSpot Meetings, and more.
A unified API removes this complexity by normalizing scheduling link data in real time across 19+ calendar and scheduling platforms. That means your product can fetch, display, and embed 'Book a Meeting' links anywhere — without maintaining per-vendor code or dealing with inconsistent metadata.
When to Use Scheduling Links
With a unified API, you can:
- Insert booking links inline across your product — in profiles, CTAs, or email templates
- Support multiple vendors with one API and unified fields
- Route meetings by team member, event type, duration, or locale
- Keep links up to date with real-time webhook-driven updates
Normalized Scheduling Objects
Unified.to provides consistent schemas across scheduling and calendar providers:
| Object | Description | Key Fields |
|---|---|---|
| scheduling_link | A shareable booking URL for a meeting template | id, url, name, event_type, duration, is_active |
| webhook | Triggers when a scheduling link or template changes | object_type, event, type, sig, nonce |
Some vendors expose 'event types' or templates — Unified normalizes the core fields while preserving vendor-specific metadata when available.
Data Flow for Scheduling Links
The workflow is simple and consistent across providers:
- Connect the user's scheduling provider via Unified Connect to obtain a
connection_id. - List
scheduling_linkobjects via the Unified API. - Display or embed links in your UI — attach them to buttons, profiles, or automated emails.
- Subscribe to webhooks to refresh or deactivate links as changes occur in real time.

Calendly, Cal.com, SavvyCal, HubSpot Meetings, Google Calendar Appointment Schedules, Microsoft Bookings, Acuity Scheduling, Apple iCloud, Fireflies, Google Meet, lemcal, Microsoft Outlook, Microsoft Teams, RingCentral, SimpleMeet.me, SquareUp, Webex, and Zoom.
