Hi,

Objective:
Create a unique calendar link for property viewings.

Issue:
I need each booking link to include pre-qualifying questions (e.g. household size, pets, etc.), but I can’t find a way to create one-off events with custom questions programmatically.

Methods attempted:

  • Tried using the API to create one-off events, but custom questions aren’t supported.

  • Looked into creating a standard event type via the API, but that doesn’t allow custom questions either.

Question:
Is there a way to automate the creation of events (one-off or otherwise) that include custom questions, or is the only option to set up event types manually in the Calendly UI?

Thanks

Hi there!

 

Thanks for outlining what you’ve already tested.

 

At this time, there isn’t a supported way to programmatically create a one-off meeting or a standard event type with new custom questions included as part of the API creation step. The current Event Type Management APIs are limited to basic event configuration, and the documented one-off event API support is limited to supported scheduling parameters such as date ranges, days in the future, and spots.

 

The closest API-supported option today is the Scheduling API / Create Event Invitee flow. That flow can capture answers to custom questions when the booking is made, but the custom questions must already exist on the underlying event type. In other words, the API can submit answers to existing questions, but it does not create or attach new custom questions on the fly.

 

So for your use case, the supported path today is to set up the event type and its custom questions in the Calendly UI first, then book against that existing event type through the API if you want to automate the scheduling flow afterward.

 

If it helps, you can also pre-fill existing custom question answers in a Calendly link using URL parameters like a1, a2, etc., but that still depends on those questions already being configured on the event type ahead of time.

 

So the short answer is yes: for now, if you need custom questions attached to the booking flow itself, the question setup has to be done in the Calendly UI.

 

That said, this is a very reasonable feature request. Being able to create one-off or event-type-based links programmatically with custom questions included would be a strong improvement for use cases like property viewings, intake flows, and lead qualification. Because of this, I've gone ahead and added this ticket to our feature request board so our product team can evaluate adding it in the future!

 

Hope this information was helpful! If you have any other questions please don't hesitate to reach out, otherwise have a wonderful day!
