Overview
Link enhances the shared invoice experience by allowing your customers to securely save their payment details for future use.
Here’s how it works:
When a customer is entering their card info, they can opt to save their payment method by entering their email and phone number. This sets up a Link account.
Then, the next time they receive a payment request from your shop, all they have to do is enter their email, authenticate, and pay — no need to re-enter card info.
The result? Faster, easier checkouts and a smoother experience that encourages repeat business.
Here's a quick walkthrough of the experience:
New Link Customers
Here’s how Link will show up for new customers:
- When entering their payment details, customers will see a prompt to sign up for link via email.
- The customer receives a one-time passcode to authenticate their session.
- After authentication succeeds, Link creates their profile and saves their card or bank payment details and shipping information (if applicable).

Existing Link Customers
Here’s how Link authenticates existing customers:
- Link automatically detects if a customer is enrolled by using their email address, phone number, or browser cookie.
- The customer receives a one-time passcode to authenticate their session.
- After authentication succeeds, Link autofills their card or bank payment details and shipping information.
After a customer enrolls with Link, they can add backup payment methods and change shipping addresses (if applicable).
