One Click Apple Pay Checkout eliminates almost all friction for customers willing to buy crypto as seamlessly as possible using Apple Pay. Customers will not be required to enter the email or any other customer or payment data.

After initiating the purchase via Paybis Onramp customers are instantly directed to the payment page where they can finish the payment in 1 click. This functionality is particularly useful for non-custodial solutions but can become a killer feature for any other partner out there.

User flow steps

1. The user opts to purchase a specific amount of cryptocurrency within the partner's app via Apple Pay.
2. Paybis On Ramp is initiated.
3. User lands on the Apple Pay checkout page and triggers Apple Pay.
4. User provides their email, and first and last names on the Apple Pay form and authorizes the payment using Touch ID or Face ID.
5. User confirms the email address in widget by entering OTP.
6. After authenticating the user, Paybis charges the funds from the user's credit card.
7. After processing the payment, Paybis initiates the cryptocurrency payout to the user's wallet.

Integration flow steps

1. Partner calls the Buy Crypto Currency Pairs API.

3. Supported currency pairs for {partnerName}-credit-card payment methods are displayed in the partner’s app.
4. The user selects the crypto wallet they want to top up and sets the amount.
5. Partner calls the POST Quote endpoint with the paymentMethod={partnerName}-credit-card.
6. Paybis returns the ID of the quote and calculated amounts for the{partnerName}-credit-card payment method.
7. Partner calls the POST Request endpoint with the following parameters:

• partnerUserId - this parameter must be unique per Request/Transaction (recommended) or per user. Note that if you use the same partnerUserId for all requests associated with a specific user, the email address confirmed during registration will always be used for authentication in the widget, and the user won't be able to change the email over time.
• quoteId - id retrieved in Step 6
• cryptoWalletAddress - recipient's wallet address to which the crypto will be sent after successful payment
• locale
• paymentMethod={partnerName}-credit-card

8. Paybis returns the requestId. Note that the unique requestId should be generated for each new transaction.
9. Partner generates widget URL with the requestId retrieved in Step 8 and indexPage=applePay as query parameters. Optional query parameters can also be added. Refer to the details here.

• Sandbox environment: https://sandbox.widget.paybis.com/?requestId={requestId}&indexPage=applePay
• Production environment: https://widget.paybis.com/?requestId={requestId}&indexPage=applePay

10. Open the generated URL with a unique requestId in the in-app browser or WebView.
11. The user lands on the Payment page with the quotation amounts and Apple Pay button. The user clicks the button to trigger Apple Pay.
12. The user provides their email, and first and last name on the Apple Pay form and authorizes the payment using Touch ID or Face ID.
13. Paybis fetches the user’s email address from Apple.
14. Paybis sends the OTP to this email address.
15. User is asked to enter the OTP to verify their email address and get authenticated in the Paybis widget. If the provided email address is incorrect, the user can enter another one in the Paybis widget and verify it.
16. Upon successful user authentication, the transaction is created on Paybis end and the Transaction Started Webhook notification is sent to the Partner.
17. Paybis processes the payment using Apple Pay token data.
18. Paybis defines whether KYC is needed to complete the transaction. If the no-KYC limit is reached and the user is not verified, then the user is asked to complete verification in the widget.

20. The user can see that the payout has started on the respective screen.
21. Paybis completes the payout and sends the Transaction Completed Webhook to the partner. The user is redirected to the transaction status screen with a link to the transaction on the blockchain.
