How to pre-fill invitee information in your Calendly link

You can customize your Calendly link to automatically fill in your invitee’s details—like name, email, or answers to questions—before they land on your booking page. This saves time and gives your invitees a smoother scheduling experience.

What you can do with a pre-filled link

  • Save your clients time by filling in their details ahead of time.
  • Pre-answer questions on the booking page for your invitees.
  • Add guests to your meeting on behalf of your invitees.

Before you begin

Customize your link

Step 1 – Copy your event link

Go to your Home page, find your event type, and select Copy Link.

Step 2 – Paste the link where you’ll send it

You can paste it into an email, text message, or other messaging tool.

Step 3 – Add a question mark (?) to the end of your link

This starts the custom information string.

Example:

https://calendly.com/yourname/meeting?name=John%20Doe

Note: If your link already includes a variable (like a calendar date), skip this step.

Step 4 – Add the variable and value you want to pre-fill

  • Use the format variable=value.
  • Use %20 to add a space between words.

Example:

?name=John%20Doe

Step 5 – Add more variables using &

To add more info, place an ampersand (&) before the next variable.

Example:

?name=John%20Doe&email=john@example.com

Information you can pre-fill

Field Variable Example
Full name  name name=John%20Doe
First name  first_name first_name=John
Last name  last_name last_name=Doe
Email  email email=john@example.com
Location  location location=Main%20Office
Custom answers  a1, a2, etc. a1=Resume%20review
Checkboxes or radios  aX=# a3=2,3
Guests guests guests=jane@example.com,john@example.com

Note

You can’t pre-fill “Other” fields for radio buttons or checkboxes where users type their own text.

Pre-fill a phone number

You can add a phone number to the link, depending on how your event collects it:

  • If the phone number comes from the event’s location (e.g. a phone call):
    • Use location=1234567890
  • If it's a custom question:
    • Use the matching variable, like a1=1234567890

Note

SMS reminder fields can’t be pre-filled.

Example full link

https://calendly.com/yourlink/consultation?name=John%20Doe&email=john@example.com&a1=Resume%20review

This will pre-fill the name, email, and first custom question response.
