Frequently Asked Questions
Answers to common questions about links, quotas, and accounts
What is included in the CalLink Free account?

How does the Custom Form Builder work?
The visual form builder (/forms) allows you to build custom registration questionnaires with 6 field types (short text, paragraph, phone number, dropdown select, multiple checkboxes, and GDPR opt-in consent). You can assign a reusable template across multiple events and preview the attendee experience in real time.

All guest responses sync instantly to your Contacts CRM, with 1-click CSV export available on Business.
Do the calendar links expire?

Yes! If you created the event under a Pro or Business account, you can update times, locations, or descriptions anytime from your dashboard. The public page and short links update dynamically.
