Pre-fill volunteer details in sign up form

Pre-fill volunteer information in the signup form

Updated over 12 months ago

This article will teach you how to pre-fill volunteer information in the signup box to streamline the signup process. 

To learn more about customizing links through Mobilize, see articles on UTM Codes, and our URL Generator.

How to set up:

  1. Navigate to your public events feed at mobilize.us/yourslug.

  2. Select the event you want to share with volunteers, then copy the link from your browser. The link should look like this:
    mobilize.us/yourslug/event/number/

3. To pre-fill first and last name: Add ?first_name=a&last_name=b to the end of your link. Replace a with your volunteer's first name and b with your volunteer's last name.

For example, the link [www.mobilize.us/mcn/event/607509/?first_name=John&last_name=Smith]
will direct the volunteer to an event page where the name John Smith is pre-filled in the signup form.

4. To pre-fill email address: Add ?email=[email protected] to the end of your link. Replace [email protected] with your volunteer's email address. 

5. To pre-fill phone number: Add ?phone=1234567890 to the end of your link. Replace 1234567890 with your volunteer's 10-digit phone number (e.g. incl. area code).

6. To pre-fill zip code: Add ?zip=12345 to the end of your link. Replace 12345 with your volunteer's 5-digit zip code.

IMPORTANT: If you want to pre-fill multiple pieces of information (e.g. first/last name, email, and zip code) to an event link, change the '?' from Steps 3-6 to '&' each time you add criteria. Your links should follow the syntax below in bold:
