Important Note: If your campaign is configured to add participants automatically through a form on your website (see image), skip this step.
First, in the code where you capture the new person's email, add them to your GrowSurf campaign as a participant with growsurf.addParticipant(). Let's say you have a signup function called signUpFree(), here's what that looks like:
your-script.js// In this example, a new person is just signing up for a free accountconst signUpFree = (userEmail) => {// ...code that registers a new user...// Then add the new user as a participant in your GrowSurf campaign:if (window.growsurf) {growsurf.addParticipant(userEmail);}};
Behind the scenes, the GrowSurf Universal Code will associate the referrer (if they exist) with the new participant. At any future date within the referral credit window, if this new participant triggers a referral, GrowSurf will provide credit to the referrer.
your-script.js// In this example, the user upgrades to a paid planconst upgradeToPaidPlan = (userEmail) => {// ...code that upgrades the user...// Then trigger this action as a referral trigger:if (window.growsurf) {growsurf.triggerReferral(userEmail);}};
Important Note: Make sure your campaign's referral trigger is set to Custom Event (see image). If the referral trigger is set to Signup Event, triggering referrals will not work since referral credit has already been provided.
Then, in the code where the action takes place, trigger the referral with growsurf.triggerReferral(). Let's say you have a function called upgradeToPaidPlan(), here's what that looks like:

Make sure you have Webhooks or Zapier set up so that rewards automatically get fulfilled to the participant once they reach a reward goal.
Sometimes you want people to access your referral campaign from any webpage. Or perhaps you just want to use buttons that look native to your website's branding instead of using the GrowSurf floating widget button.
Add the Embedded Button anywhere in your HTML
Just paste <div data-grsf-block-button></div> anywhere in your HTML, and clicking the element will open up the GrowSurf window.
index.html<!-- Here's the simplest solution: --><div data-grsf-block-button></div><!-- Here's a customized solution: --><div data-grsf-block-buttondata-grsf-button-style="{'background-color': '#117a8b', 'font-family': 'Arial', 'color': '#FFFFFF', 'border-radius': '6px' }"data-grsf-button-text="Join My Referral Program"></div>
Just add onclick="growsurf.open()" to any HTML element, and clicking it will open up the GrowSurf window.
index.html<!-- Works on any HTML element. Here's a <div> example: --><div onclick="growsurf.open()">Refer Friends</div><!-- Here's a <button> example: --><button onclick="growsurf.open()">Refer Friends</button>
Add the Embedded Form anywhere in your HTML
Just paste <div data-grsf-block-form></div> anywhere in your HTML, and the GrowSurf form will appear. If you want your participant to be already logged in and see their stats (instead of the form), you can add an attribute data-grsf-email to have the value of the participant's email.
Important Note:
If you have participant authentication enabled for your campaign, then the participant's unique share link and social buttons will only display if the participant entered your referral program from their browser (either via automatic form detection, via the GrowSurf form, or via JavaScript Web API). This is because a browser cookie will be saved that identifies the participant. Otherwise, the signup form will be shown, and the participant can click the login link to get sent a one-time login email.
index.html<!-- Providing just this code will make the GrowSurf form appear: --><div data-grsf-block-form></div><!-- Add a `data-grsf-email` attribute to authenticate the participant: --><div data-grsf-block-formdata-grsf-email="gavin@hooli.com"></div><!-- You can also completely customize the Embedded Form, shown in this example --><div data-grsf-block-formdata-grsf-email="gavin@hooli.com"data-grsf-button-style="{'background-color': '#5890E7', 'color': '#fcfcfc', 'font-family': 'Sans', 'font-size': '12px'}"data-grsf-email-button-style="{'background-color': '#5890E7', 'color': '#fcfcfc', 'font-family': 'Arial', 'font-size': '12px'}"data-grsf-email-button-text="Share"data-grsf-twitter-button-style="{'background-color': '#5890E7', 'font-family': 'Arial', 'font-size': '12px'}"data-grsf-twitter-button-text="Share"data-grsf-facebook-button-style="{'background-color': '#5890E7', 'font-family': 'Courier New', 'font-size': '12px'}"data-grsf-facebook-button-text="Share"data-grsf-pinterest-button-style="{'background-color': '#5890E7', 'letter-spacing': '1.2', 'font-size': '12px'}"data-grsf-pinterest-button-text="Pin It"data-grsf-share-instructions="Share this unique link with your friends"></div>
Fetch a participant's information using growsurf.getParticipantByEmail().
Here's an example of retrieving the participant data, then updating the #share-url and #referral-count HTML elements to show their unique referral link and referral count.
index.html<!DOCTYPE html><html><head><title>Your Referral Stats</title><!-- The GrowSurf Universal Code --><script type="text/javascript">(function(g,r,s,f){g.growsurf={};g.grsfSettings={campaignId:"REPLACE_ME_WITH_YOUR_CAMPAIGN_ID",version:"2.0.0"};s=r.getElementsByTagName("head")[0];f=r.createElement("script");f.async=1;f.src="https://growsurf.com/growsurf.js"+"?v="+g.grsfSettings.version;f.setAttribute("grsf-campaign", g.grsfSettings.campaignId);!g.grsfInit?s.appendChild(f):"";})(window,document);</script></head><body><input id="share-url" type="text" disabled><div id="referral-count"></div><script>// Listen and wait for Growsurf to initializewindow.addEventListener('grsfReady', () => {const participantEmail = 'sarah@website.com'; // replace with your user's email// Get the GrowSurf participant's informationgrowsurf.getParticipantByEmail(participantEmail).then(participant => {document.getElementById("share-url").value = participant.shareUrl;document.getElementById("referral-count").innerHTML = participant.referralCount;});});</script></body></html>
This is for when you want to redirect to another webpage after a participant successfully signs up for your referral campaign.
If you are using the Embedded Form, you can add the following HTML attribute: data-grsf-redirect-url.
Remember to replace https://replaceme.com with your redirect URL.
<div data-grsf-block-formdata-grsf-redirect-url="https://replaceme.com"></div>
If you are using your own form via automatic form detection or JavaScript Web API, then include the following snippet of code within the <HEAD> of the HTML source code. This should be the same page(s) where you have included the GrowSurf Universal Code. Remember to replace https://replaceme.com at line 7 with your redirect URL.
<script>// Listen and wait for the Growsurf Universal Code to initializewindow.addEventListener('grsfReady', () => {console.log('GrowSurf is Ready!');// Your redirect code goes here....growsurf.subscribe('signup', (participant) => {window.location.replace("http://replaceme.com");});});</script>
Please note: If the redirect is not working, it is most likely because the form submission is failing. If this is the case, please check your browser console for errors.
When a new visitor lands on your site from using their friend's unique link, you can personalize a message for them with growsurf.getReferrerId() and growsurf.getParticipantById(). In this example, we have a simple page with a h1#header that will display as "Emily S. invited you to pet puppies on-demand" if a referrer exists, otherwise it will display as "Pet puppies on-demand".
<html><body><h1 id="header">Pet puppies on-demand</h1></body><script>window.addEventListener('grsfReady', () => {const referrerId = growsurf.getReferrerId();if (referrerId) {growsurf.getParticipantById(referrerId).then(participant => {if (participant) {const { firstName, lastName } = participant;const newHeader = `${firstName && lastName ? firstName + ' ' + lastName.charAt(0) + '. invited you to pet puppies on-demand' : 'Pet puppies on-demand'}`;const headerEl = document.getElementById('header');headerEl.innerHTML = newHeader;}});}});</script></html>
