Tracking & Pre-fill

Create named tracking links per source and generate pre-fill links with field values already populated

Tracking & Pre-fill help you understand where submissions come from and make forms faster to complete for specific audiences.

Source Tracking

Create named tracking links for each traffic source. Each link uses the same form URL but tags submissions with the source name, so you can see where responses originated.

Common tracking sources:

Source name	Channel
x	Posts on X (Twitter)
facebook	Facebook posts or ads
tiktok	TikTok bio or posts
email	Email campaigns
website	Links from your own site

Each tracking link has a Copy Link button and a QR code icon for quick sharing.

Creating a Tracking Link

1. Open Tracking & Pre-fill

   Go to your form → Settings → Tracking & Pre-fill.

2. Add a source

   Enter a name for the source (e.g. instagram).

3. Copy the link

   Copy the generated tracking link and use it when sharing to that channel.

Pre-fill Links

Generate a link with certain fields already completed. Useful for personalized invitations or when you already know some of the submitter’s data.

Creating a Pre-fill Link

1. Open Tracking & Pre-fill

   Go to your form → Settings → Tracking & Pre-fill and find the Pre-fill section.

2. Name the link

   Enter a descriptive name so you can identify this pre-fill link later.

3. Set field values

   Choose which fields to pre-fill and enter the values.

4. Copy the link

   Copy the generated URL with pre-fill parameters included.

Use a pre-fill link with a locked field to pass a referral code or event name that submitters can’t change.
