Know who sent the next customer.

A signup page that grows by recommendation: every member leaves with a link of their own, and the next signup arrives knowing who sent them.

Referred by

Rowan Rune

Their own code

RUNE-9T4

The code in the link is matched to the entry that issued it.

Referrer Thank-you sent

A valid code connects the signup to its referrer

Illustrative experience

A code for every signup
The referrer read from the link
A thank-you for the referrer

The finished experience

Word of mouth you can actually see.

Every signup arrives with its referrer attached, so the thank-you goes out without anyone matching names.

A good fit for
Membership sites, courses and anything that grows by recommendation.

1

Give every signup a code

Unique ID stamps each entry with the code that becomes that customer’s referral link.

2

Read the code on the way in

The referral link carries the code in the URL, and Populate Anything looks up the entry that issued it, dropping the referrer’s name and email into hidden fields.

GP Populate Anything
3

Thank the referrer

Condition a notification on finding a valid referral record and send it to the referrer’s populated email address. The entry records who referred the new signup.

Inspired by a real build

Spotlight: Populate Anything & Unique ID for Automated Referral Programs May 2023 Chris Odell built an automated referral and rewards program using Gravity Forms and Gravity Perks. We explore how it works, step by step. Read the spotlight

What you’ll need.

Start with Gravity Forms. Add the capabilities this solution needs, then make the experience your own.

GP Unique ID

Mints the referral code on every signup, so each customer has something of their own to share.

GP Populate Anything

Reads the code out of the referral link and looks up the entry that issued it, so the right person is credited.

Taking it further

Add these optional plugins when your project calls for more.

Optional

GP eCommerce Fields

Optional Discount Field variant: applies a discount after a valid referral record is found. Required only for that eCommerce Fields variant, not basic referral tracking.

Optional

GP Advanced Conditional Logic

Optionally compares the signup and referrer email fields to show a self-referral warning or hide Submit. This is an interface deterrent, not server-side validation.

Explore GP Advanced Conditional Logic

Before you start

A signup form with unique referral codes and a link that carries the code.
For the optional eCommerce Fields Discount Field variant: GP eCommerce Fields, a configured Discount field, and a valid-referral condition. Taking payment also needs an official payment add-on, connected account and payment feed.
Check eligibility separately if a reward is limited to a first order. Neither a valid referral code nor a Discount field establishes that this is the customer’s first purchase.

What stops someone using their own code?

The entry records who referred whom for review. Optionally use GP Advanced Conditional Logic to compare the signup email with the populated referrer email and show a warning or hide Submit when they match. That deters ordinary self-referrals in the interface; enforce the rule server-side if it must resist crafted submissions.

Does the reward have to be a discount?

No. A thank-you notification or a reward you apply after review can use the same attribution record. An optional eCommerce Fields Discount Field can discount the referred signup when a valid code is found, as suggested in a staff reply on the spotlight. That extension does not implement first-order eligibility, and other discount approaches have their own requirements.
