The Branding → Referral Sharing section lets you customise the messaging customers see when they share a referral link or when a referred friend arrives at your store. There are three separate cards here, each targeting a different moment in the referral journey.

Customise the text shown to customers on the checkout thank you page prompting them to share their referral link. This is the message a customer sees after placing an order, encouraging them to refer a friend.

Click Setup → opens the Theme Editor for the checkout thank you page.

Customise the popup shown to referred friends when they visit your store via a referral link. This is the first thing a referred customer sees — make sure it clearly communicates their reward.

Click Setup → opens the Theme Editor for the referral landing experience.

Customise the guest referral sharing experience shown after checkout for customers who don't have an account. This targets non-member shoppers, giving them a way to refer friends even without being signed into a loyalty account.

Click Setup → opens the Theme Editor for the post-checkout guest referral sharing flow.

Casa Loyalty → Branding → scroll down to the "Loyalty Nudges" section → the Referral Sharing group appears directly below the Account Creation / Points Spending / Reward Usage nudge cards.
