How do I connect HelloForms to Calendly?

In Calendly, create a personal access token with scheduling access. Copy the API URI of the event type submissions should book into. Paste both below and send a test event — Calendly returns a one-time booking link. You can do the whole thing from the form's Integrations tab — no code and no developer account required.

What do I need before I start?

You need calendly personal access token, event type uri. Everything else is configured in HelloForms.

What does Calendly receive for each submission?

A single-use Calendly booking link for your chosen event type, recorded with the submission. You choose which questions are included, so fields you would rather keep private never leave HelloForms.

Is the Calendly integration available on the free plan?

Yes. Delivery destinations are part of the product rather than a paid add-on, so you can connect and test one on a free form before upgrading.

What happens if a delivery to Calendly fails?

Transient failures are retried automatically with exponential backoff, and every attempt is written to the delivery log with the status code and the response body the provider returned. Repeated hard failures disable the destination instead of retrying forever, and you can retry a specific submission from the response.

Where are my credentials stored?

Tokens and secrets are stored server-side, are never rendered in your published form, and are shown masked in the dashboard. Delivery happens from the server, so nothing is exposed to respondents.

Can I reuse the same Calendly connection on other forms?

Yes. Save it as an account-level connection once and pick it from the credentials selector when you add the destination to another form — you never re-enter the token.

Create Calendly booking links from form responses

Ask the qualifying questions in HelloForms and paste a Calendly personal access token plus the event type URI. Each submission creates a single-use booking link for that event type, so only qualified respondents can take a slot.

What the Calendly integration does

One booking link per submission, created through Calendly's API rather than a shared public link.
Qualify before booking, so bad-fit calls drop out before they reach your calendar.
The structured answers stay in your HelloForms inbox alongside the link that was issued.

What it looks like

A single-use Calendly booking link for your chosen event type, recorded with the submission.

How to connect Calendly to your form

1
In Calendly, create a personal access token with scheduling access.
2
Copy the API URI of the event type submissions should book into.
3
Paste both below and send a test event — Calendly returns a one-time booking link.

What you’ll need

Calendly personal access token.
Event type URI — Copy it from GET /event_types, or from the event type's API details.

Credentials are stored server-side and never rendered in your published form. Every delivery attempt is logged, transient failures are retried with backoff, and repeated failures disable the destination instead of retrying forever.

Configuration template and sample payload

Download a filled-in checklist of every value the Calendly destination asks for, plus an example of exactly what Calendly receives for one submission — useful for planning a mapping or handing the setup to a developer.

Every field the "Add integration" dialog asks for, with placeholders to fill in. Keep it as documentation of your Calendly mapping — do not commit a completed copy to a public repository.
