Smart Links
Create calendar events
automatically.
======================================
A **Smart Link** turns a plain URL or a button into a calendar event. Wire it into a form, a CRM, Zapier, or your own code, and events get created and synced everywhere on their own.

How it works
Three steps to automated events
---------------------------------
1
### Create a Smart Link
Make a Smart Link in your dashboard and point it at a calendar. Turn on approval if you want to review events first.
2
### Pass event details
Add event details as URL parameters or button data attributes, from a form, a CRM, Zapier, or your own code.
3
### One event, everyone adds it
AddCal saves it as a single event you own. Everyone who opens the link adds that same event to their own Google, Apple, or Outlook calendar. Same details never create a duplicate.
Ways to use it
Three ways to fire a Smart Link
---------------------------------
Pick whatever fits the tool you already use.
URL parametersEmbed buttonAutomation tools
### URL parameters
Build a link with event details as parameters. Anything that can produce a URL can create a calendar event.
- Plain URL, no SDK or code needed
- Works from any tool that builds links
- Drop it in emails, buttons, or QR codes
### Embed button
Add a button to any site with event details as data attributes. Great for CRM templates and dynamic pages.
- Dynamic details via data attributes
- Works with any website builder
- Styled and responsive out of the box
### Automation tools
Wire Smart Links into Zapier, Make, or any tool that can fire an HTTP request, and create events from any trigger.
- Works with 8000+ apps via Zapier
- No-code automation workflows
- Trigger from forms, CRMs, and orders

Marketers & developers
No code? No problem.
---------------------
A Smart Link is just a URL, so you can build one with merge fields in your email tool, or wire it into a backend. Whatever is easier for you.
### Use merge fields, no code
Paste your email or CRM tool's merge tags straight into the link. Each contact gets their own event, personalized, with nothing to build.
### Just a link or a button
A Smart Link is a plain URL. Anything that can build a link, Mailchimp, HubSpot, a form, a button, can create a calendar event.
### Safe to send at scale
Identical details resolve to the same event, so a campaign blast or a webhook firing twice never doubles up on the calendar.
In an email or CRM, swap the values for merge tags
Mailchimp title=\*|EVENT\_TITLE|\*
HubSpot date\_start={{event.start}}

This is a live Smart Link on a shared demo calendar. Opening it really creates the event and lands you on its add-to-calendar page.
Features
Built for dynamic event creation
--------------------------------
### Dynamic URL parameters
Create events on the fly from any link. Pass title, dates, timezone, location and description as parameters.
### Embeddable buttons
Drop a Smart Link button on any site. Event details come from data attributes, no coding required.
### Works with your tools
Hook into Zapier, Make, IFTTT, or anything that can build a URL or fire an HTTP request.
### Optional approval
Turn on approval and incoming events wait for your review before they appear on the calendar.
### No accidental duplicates
The same parameters always resolve to the same event, so retries and double-fires stay clean.
### Synced everywhere
Events land in your AddCal calendar and sync to Google, Apple, Outlook, Office 365 and Yahoo.
Stay in control
You decide what makes the calendar
------------------------------------
Automate event creation without giving up control. Keep links private with their own key, and review anything before it goes live.
### Secret link key
Every Smart Link has its own random key. Only requests that know the key can create events on your calendar.
### Hold for approval
Flip on approval and new events arrive as pending. Nothing shows on your calendar until you say so.

FAQ
Smart Links, answered
---------------------
### What are Smart Links and how do they work?
A Smart Link is a URL that turns event details into a calendar event. The first time someone opens a link with a given set of details (title, date, time), AddCal saves it as one event on your AddCal calendar. Everyone who opens that same link adds that same event to their own Google, Apple, or Outlook calendar. That makes them perfect for integrations, automations, and any time you want an event created without doing it by hand.
### How do I create events using Smart Links?
Append event details as URL parameters to your Smart Link. For example: addcal.co/s/your-key?title=Meeting&date_start=2026-05-24T15:00:00&date_end=2026-05-24T16:00:00&timezone=America/New_York. The event is created automatically and synced to your calendars.
### What parameters can I use with Smart Links?
Title and a start date are required. You can also pass an end date or a duration in minutes, a timezone, a description, a location, and whether it is an all-day event. If you leave the timezone out, the calendar default is used.
### Can I use Smart Links with automation tools?
Yes. Smart Links work with Zapier, Make, IFTTT, and any platform that can build a URL or fire an HTTP request. You can also use them straight from your own backend, since there is nothing to install.
### Are Smart Links secure?
Each Smart Link has its own random secret key, so only requests that know the key can create events. You can also turn on approval, which holds incoming events as pending until you review and approve them, so nothing reaches your calendar without your say-so.
### What counts as an event?
An event is one unique set of details, no matter how many people add it to their calendars. A link for "Webinar, July 12" is one event whether 5 people or 5,000 open it. Change the details in the link (a different date or title) and you get a new event. The plan limits below count events, not clicks or adds.
### Should I use Smart Links or Dynamic Links?
Use Smart Links when the event is the same for everyone (a webinar, a launch, a class). Because the event lives in AddCal, you get full analytics: views, adds, a breakdown by calendar app, and RSVPs. Use Dynamic Links when each recipient gets different details (their own meeting link, seat, or address), where you need a personalized add-to-calendar link rather than a shared event.
### Will the same trigger create duplicate events?
No. Identical details always resolve to the same event, so if a webhook fires twice or someone refreshes the link, you still end up with a single event on your calendar.
### Is there a limit on Smart Links?
You can create as many Smart Links as you like on every plan. The free plan is meant for testing and caps the events created through Smart Links at 5 per month. Premium raises that to 200 events a month and Business is unlimited, so you can run them in production. The limit counts unique events, not how many people add each one.
### Do Smart Links work with all calendar platforms?
Events created via Smart Links land in your AddCal calendars and sync to Google Calendar, Apple Calendar, Microsoft Outlook, Office 365, Yahoo, and any app that supports the standard .ics format.

What customers say
Loved by the people who run events.

> “Our attendance rate for funnel events was about 35%. We replaced our confirmation page and emails with AddCal links and we're above 60% now.”
Rachel Kim

> “Parents kept missing school events because nobody checks the website. We switched our calendar to AddCal, now it's a public page they subscribe to. Game changer.”
Daniel Ortega
Communications Director · K-12 School District
> “We do a weekly tech webinar and used to have a whole separate tool just for RSVPs. AddCal handles that plus the calendar link so it's one less thing to maintain.”
