How can I make an upfront discount available to a referred friend?

Let's say you want to offer a double-sided reward where the referred friend gets an upfront discount before a purchase is made or a signup happens (e.g., "Get 20% off your first invoice!"). GrowSurf supports the following integrations to implement this workflow:

Stripe

Follow the instructions here.

Chargebee

Follow the instructions here.

Recurly

Follow the instructions here.

Not using any of those integrations?

Use our JavaScript method growsurf.validateReferrer()   to check if a referral is valid, then apply a coupon. Here is a code example:

function applyCouponCode() {
  const isReferralLinkValid = growsurf.validateReferrer();
  if (isReferralLinkValid) {
    // Apply your custom coupon code here
  }
};

// Check to see if GrowSurf is available
if (!window.growsurf) {
  // Listen and wait for the Growsurf Universal Code to initialize
  window.addEventListener('grsfReady', () => {
    console.log('GrowSurf is ready!');
    applyCouponCode();
  });
} else {
  console.log('GrowSurf is already available');
  applyCouponCode();
}

Notes:

• Upfront discounts are only available for referral programs (affiliate programs are not supported).
• Upfront discounts cannot be used with dynamic rewards.
• If you still want to apply upfront discounts, we recommend creating a single-sided reward and utilizing growsurf.validateReferrer() then applying your own coupon code for referred visitors.
