iOS Drop-in

Our iOS Drop-in renders Cash App Pay in your payment form, and redirects the shopper to complete the payment.

Before you begin

This page explains how to add Cash App Pay to your existing iOS Drop-in integration.

Before starting your Cash App Pay integration:

  1. Make sure that you have set up your back end implementation, and added Drop-in v5.2.0 or later to your payment form.
  2. Add Cash App Pay in your Customer Area. You will need your Cash App client ID to do this.

Install the Adyen iOS client-side library

API reference

You don't need to send additional fields for Cash App Pay. To see optional fields that you can send for all payment methods, choose the endpoint you integrated:

Drop-in configuration

To add Cash App Pay to your Drop-in integration, set the cashAppPay property of Drop-in's configuration instance.

dropInConfiguration.cashAppPay = CashAppPayConfiguration(redirectURL: URL(string: "yourAppURLOrScheme"))

Set your AdyenSession instance as Drop-in's delegate to let it handle the flow.

dropIn.delegate = self.session

Present the Drop-in's view (modally, in a navigation stack, and so on).


Optional configuration

You can add the following optional configuration:

Parameter name Description Default
showsStorePaymentField Set to false if you don't want to show a toggle to lets the shopper choose whether to save their payment details. true
storePaymentMethod Set to true to save the shopper's payment details without asking if they want to. Set showsStorePaymentField to false if you use this. false

Show the payment result

Use the  resultCode from the /sessions or /payments response to show the payment result to your shopper. You will also receive the outcome of the payment asynchronously in a webhook.

For Cash App Pay payments, you can receive the following resultCode values:

resultCode Description Action to take
Authorised The payment was successful. Inform the shopper that the payment has been successful.
If you are using manual capture, you also need to capture the payment.
Cancelled The shopper cancelled the payment. Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.
Error There was an error when the payment was being processed. For more information, check the refusalReason field. Inform the shopper that there was an error processing their payment.
Refused The payment was refused. For more information, check the refusalReason field. Ask the shopper to try the payment again using a different payment method.

Recurring payments

Adyen's tokenization service allows you to securely store the shopper's payment details for recurring payments. To make recurring Cash App Pay payments, you first need to create a shopper token, and then use the token to make future payments for the shopper.

Create a token

Include the storedPaymentMethodMode parameter in your /sessions request. Possible values:

Value Description
disabled (default) Don't store payment details.
askForConsent If shopperReference is included in the request, show a toggle in the payment form that lets the shopper choose whether to save their payment details.
enabled If shopperReference is included in the request, store the shopper's payment details without asking them.

The Cash App SDK requires you to specify whether to create a recurring request. If you set storedPaymentMethodMode to enabled or disabled, you must also specify the following in your configuration:

  • storedPaymentMethod: To store the payment method. This property is ignored if showsStorePaymentMethodField is true.

If you or the shopper chooses to store payment details, your instance of AdyenSession creates a token when the shopper pays.

Make a payment with a token

When the shopper pays, your instance of AdyenSession includes the shopper's stored Cash App Pay details. You can also use tokens to make shopper-not-present payments for subscriptions or contracts.
