How Google Calendar URL Links Work Under the Hood

A Google Calendar link is a specially structured web URL that opens the Google Calendar web interface with pre-filled event fields (title, dates, location, description).

The base endpoint is:

code

https://calendar.google.com/calendar/render?action=TEMPLATE

The Key Query Parameters

Parameter	Purpose	Example
code `text`	Event title / Summary	code `text=Q4+Product+Launch`
code `dates`	Start and End timestamps ( code `YYYYMMDDTHHMMSS/YYYYMMDDTHHMMSS` )	code `dates=20261015T140000Z/20261015T150000Z`
code `details`	Event description, links, and agenda	code `details=Join+us+live+at+zoom.us`
code `location`	Physical address or video conference URL	code `location=https%3A%2F%2Fzoom.us%2Fj%2F123`

Handling Time Zones Correctly

When constructing date strings manually, the safest approach is to use UTC timestamps with a trailing

code

(e.g.

code

20260910T150000Z

Google Calendar will automatically adjust the display time to match the attendee's local device time zone wherever they are in the world.

Automating Link Creation with the CalLink API

If you need to generate calendar links dynamically inside your CRM, Zapier, Make, or backend application, you can use the CalLink Pro REST API:

bash
curl -X POST "https://cal-link.com/api/v1/generate-links" \
  -H "x-api-key: cl_your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Onboarding Call with Alex",
    "description": "Discuss your roadmap and Q4 goals.",
    "location": "https://meet.google.com/abc-defg-hij",
    "start_time": "2026-09-20T10:00:00Z",
    "end_time": "2026-09-20T11:00:00Z"
  }'

The API returns pre-formatted links for Google, Outlook, Office 365, Yahoo, and download-ready

code
