Apple Pay

Introduction

Apple Pay is a payment method which allows to process payments in different currencies by using Apple Pay services in different regions. This method supports one-time and credential-on-file purchases, refunds and payment card verification.

This article provides information about working with the Apple Pay method: general insights are presented in the Overview section, while information about the actions required to process payments and perform other actions is presented in the sections that follow.

General information

Interaction diagram

Payment processing by using the Apple Pay method involves the merchant's web service, one of ecommpay interfaces, the ecommpay payment platform, and technical facilities of the Apple Pay service.

Operations support

Various platform interfaces can be used to process payments and perform operations using the Apple Pay method. Purchases can be processed by using Payment Page, Gate and Dashboard (using payment links), refunds—by using Gate and Dashboard.

Processing scenarios

To perform a purchase by using the Apple Pay method, the payment session must be initiated and the customer needs to perform the required steps, while to make a refund you need to receive a request from the customer and notify the customer about the result of the refund via the web service.

Scenarios for performing operations via the main interfaces of the payment platform correspond to those presented in the diagrams. Similarly, when additional features (such as payment links) are used, scenarios for performing operations also correspond to the specifics of those features.

General information

To process a purchase through Payment Page by using the Apple Pay method, the merchant's web service is required to send a request with all required parameters and signature to the ecommpay URL and receive a callback with the result. The full sequence and special aspects of purchase processing are provided below.

Information about the formats of requests and callbacks used for processing payments by using the Apple Pay method via Payment Page is presented further in this section; general information about working with the Payment Page API is presented in Interaction concepts.

Request format

There are several things you need to consider when sending purchase requests by using the Apple Pay method:

1. The following parameters required for any payment must be specified:
   • project_id—project identifier obtained from ecommpay during integration
   • payment_id—payment identifier unique within the project
   • payment_currency—payment currency code in the ISO-4217 alpha-3 format
   • payment_amount—payment amount in the smallest currency unit
   • customer_id—customer identifier unique within the project
2. The following parameters required for any payment must be specified: project_id, payment_id, payment_currency, payment_amount, customer_id.
3. If you need to have payment form displayed with the Apple Pay method selected, set the force_payment_method parameter to:
   • apple_pay_core—to open Payment Page with pre-selected payment method Apple Pay
   • card—for the ability of payment by using either a payment card or Apple Pay. In this case customer can chose the payment method on Payment Page
4. Additionally, any other parameters available for working with Payment Page can be used (details).
5. After all target parameters are specified, generate a signature (details).

Thus, a correct request for opening the payment form using the Apple Pay method must contain the project identifier, basic payment information (identifier, amount, and currency code), customer identifier and signature.

{
   "project_id": 120,
   "payment_id": "580",
   "payment_amount": 1000,
   "payment_currency": "USD",
   "customer_id": "customer1",
   "signature": "kUi2x9dKHAVNU0FYldOcZzUCwX6R\/ekpZhkIQg=="
}

{
   "project_id": 120,
   "payment_id": "580",
   "payment_amount": 1000,
   "payment_currency": "USD",
   "customer_id": "customer1",
   "signature": "kUi2x9dKHAVNU0FYldOcZzUCwX6R\/ekpZhkIQg=="
}

Callback format

The Apple Pay method uses the standard format for callbacks to deliver purchase results. For more information, see Callbacks.

The following is the example of a callback with information about a 1,000.00 USD purchase in the 580 project.

General information

The Apple Pay payment method provides the ability to perform COF purchases—regular on-demand payments. For more information about COF purchases, see On-demand COF purchase.

Registration of a COF purchases is also available by using Payment Page. For registration the web service must send a request containing the required parameters and signature, as well as data for registering a COF purchase in the recurring object, to the ecommpay URL and accept a callback with the result. In the callback about registering a COF purchase, you will get its ID, which you need to use to make or cancel regular payments via Gate or Dashboard. For more information, see the section COF purchases by using Gate.

Information about the formats of requests and callbacks used for processing payments by using the Apple Pay method via Payment Page is presented further in this section; general information about working with the Payment Page API is presented in Interaction concepts.

Request format

There are several things you need to consider when sending purchase requests for registering COF purchases by using the Apple Pay method:

1. The following parameters required for any payment must be specified:
   • project_id—project identifier obtained from ecommpay during integration
   • payment_id—payment identifier unique within the project
   • payment_currency—payment currency code in the ISO-4217 alpha-3 format
   • payment_amount—payment amount in the smallest currency unit
   • customer_id—customer identifier unique within the project
2. The following parameters required for any payment must be specified: project_id, payment_id, payment_currency, payment_amount, customer_id.
3. To register a COF purchase, you must specify a recurring object containing the registration attribute and the necessary information. To register regular payments, the request must contain information about the frequency, amount, and beginning and end time of regular payments. The full list of parameters that can be passed in the recurring object is shown in the COF purchase registration section.
4. If you need to have payment form displayed with the Apple Pay method selected, set the force_payment_method parameter to:
   • apple_pay_core—to open Payment Page with pre-selected payment method Apple Pay
   • card—for the ability of payment by using either a payment card or Apple Pay. In this case customer can chose the payment method on Payment Page
5. Additionally, any other parameters available for working with Payment Page can be used (details).
6. After all target parameters are specified, generate a signature (details).

Thus, a correct request for opening the payment form using the Apple Pay method must contain the project identifier, basic payment information (identifier, amount, and currency code), customer identifier and signature.

Information about the formats of requests and callbacks used for processing payments by using the Apple Pay method via Gate is presented further in this section. General information about working with the Gate API is presented in Interaction concepts.

COF purchase registration

To register a COF purchase by using Gate, the merchant is required to send a request for purchase with all the required parameters (including the register parameter of the recurring object, set to the value true) to the ecommpay URL and get the callback with the payment result from the payment platform. To register a regular payment the request should also contain information about the frequency, amount, start and end dates of regular payments. The COF purchase registration callback contains its identifier, which can be used to process or cancel regular payments.

For more information about purchase processing by using Gate, see Purchases by using Gate.

Format of requests for registration of COF purchases

There are several things you need to consider when sending requests for registering COF purchases by using the Apple Pay method:

1. To register each COF purchase, send a separate POST request to one of the following endpoints: /v2/payment/applepay/sale or /v2/payment/applepay/auth.
2. Each request must include the following objects and parameters:
   • Object general—general purchase information:
     • project_id—project identifier obtained from ecommpay during integration
     • payment_id—payment identifier unique within the project
     • signature—request signature generated after all required parameters are specified (details—in the Signature generation and verification) (details)
   • Object payment—payment information:
     • amount—payment amount in the smallest currency unit
     • currency—payment currency code in the ISO-4217 alpha-3 format
   • Object customer—customer information:
     • id—customer identifier unique within the project
     • ip_address—customer IP address relevant for the initiated payment
   • Object recurring—COF purchase information:
     • register—payment registration as a COF purchase
     • type—type of the COF purchase: R (for Regular payment), C (for OneClick payment), or U (for Autopayment), for more information, refer to Overview
     • scheduled_payment_id—identifier of the next COF purchase
     • start_date—the start date of regular payments, in the DD-MM-YYYY format (must be at least one day later than the date of registration)
     • amount—amount of debiting
     • period—regular payment performing period
     • interval— regular payment performing interval
     • time—regular payment performing time in the hh:mm:ss (UTC0) format
3. Additionally, any other parameters included in the specification can be used.

Thus, a correct COF purchase registration request by using the Apple Pay method must contain the project identifier, basic payment information (identifier, amount, and currency code), customer identifier and IP address, the registration parameter and the conditions for regular payments, as well as signature.

Format of requests for COF purchase processing

After the payment is registered, the funds are debited according to the specified regular payment conditions. You initiate COF purchase by sending a recurring request to the payment platform.

There are several things you must consider when processing COF purchases performing by using the Apple Pay method:

1. To process each purchase, send a separate POST request to the /v2/payment/applepay/recurring endpoint.
2. Each request must include the following objects and parameters:
   • Object general—general purchase information:
     • project_id—project identifier obtained from ecommpay during integration
     • payment_id—payment identifier unique within the project
     • signature—request signature generated after all required parameters are specified (details—in the Signature generation and verification) (details)
   • Object payment—payment information:
     • amount—payment amount in the smallest currency unit
     • currency—payment currency code in the ISO-4217 alpha-3 format
   • Object customer—customer information:
     • ip_address—customer IP address relevant for the initiated payment
   • Object recurring—COF purchase information:
     • id—registered COF purchase identifier
3. Additionally, any other parameters included in the specification can be used.

Thus, a correct purchase request by using the Apple Pay method must contain the project identifier, basic payment information (identifier, amount, and currency code), customer IP address, COF purchase identifier, as well as signature.

}

Format of request for cancellation of COF purchases

Until the expiration date of a COF purchase, you can cancel it. Also, to change the conditions of COF purchases, you must cancel it and send a request to register a new one.

There are several things you must consider when cancelling COF purchases by using the Apple Pay method:

1. To cancel each purchase, send a separate POST request to the /v2/payment/applepay/recurring/cancel endpoint.
2. Each request must include the following objects and parameters:
   • Object general—general purchase information:
     • project_id—project identifier obtained from ecommpay during integration
     • payment_id—payment identifier unique within the project
     • signature—request signature generated after all required parameters are specified (details—in the Signature generation and verification) (details)
   • Object recurring—COF purchase information:
     • id—registered COF purchase identifier
3. Additionally, any other parameters included in the specification can be used.

Thus, a correct purchase request by using the Apple Pay method must contain the project, payment and COF purchase identifiers, as well as signature.

General information

To perform a payment card verification by using Apple Pay method, the merchant web service must send a request with all the required parameters and signature to ecommpay URL, and receive a callback with the information about the result. Payment card verification processing for this method is the same as standard processing sequence which is provided in the section Payment instrument verification.

Format of request for payment card verification

There are several things you need to consider when sending payment card verification requests by using the Apple Pay method:

1. To initiate each verification, send a separate POST request to the /v2/payment/applepay/account_verification endpoint.
2. Each request must include the following objects and parameters:
   • Object general—general purchase information:
     • project_id—project identifier obtained from ecommpay during integration
     • payment_id—payment identifier unique within the project
     • signature—request signature generated after all required parameters are specified (details—in the Signature generation and verification) (details)
   • Object payment—payment information:
     • amount—payment amount in the smallest currency unit
     • currency—payment currency code in the ISO-4217 alpha-3 format
   • Object customer—customer information:
     • id—customer identifier unique within the project
     • ip_address—customer IP address relevant for the initiated payment
   • etoken— information about token that represents card details received from the Apple Pay service:
     • token—token received from Apple Pay in JSON format after user identification, must be specified as a string. The value of this parameter can contain such information as the payment identifier on the Apple Pay side, the type of the international payment system, and various service data.

       {
          "paymentData":{
             "version":"EC_v1",
             "data":"perkYfGgfMXL/lTG DCSDfR7x4Qz2E/p7WZqBBJJ+/z2iWUIEBNDsovnwhwTeVXAAAAAAAA==",

             }
          },
          "paymentMethod":{
             "displayName":"Visa 1005",
             "network":"Visa",
             "type":"debit"
          },
          "transactionIdentifier":"TFDG767HGSFDSJ7AL4435393E5882652"
       }

       "token": "{"paymentData":{"version":"EC_v1","data":"perkYfGgfMXL/lTGDCSDfR7x4Qz2E/p7WZqBBJJ+/z2iWUIEBNDsovnwhwTeVXAAAAAAAA==","header":{"ephemeralPublicKey":"MWnwEQ==","publicKeyHash":"tl+QgkoijbTvIomdnCLsdfbvwauh5656we9wvth2+1w=","transactionId":"u85785def5ce96a8ada846sre2v6r6yry5htj93e50152"}},"paymentMethod":{"displayName":"Visa 1005","network":"Visa","type":"debit"},"transactionIdentifier":"TFDG767HGSFDSJ7AL4435393E5882652"}"

3. The payment amount must be zero.
4. Additionally, any other parameters included in the specification can be used.

Thus, a correct purchase request by using the Apple Pay method must contain the project identifier, basic payment information (identifier, amount, and currency code), customer identifier and IP address, Apple Pay token information, as well as signature.

General information

For the Apple Pay method, it is possible to test one-step and two-step purchases by using Payment Page and Gate, as well as payment card verification by using Gate. To enable and disable testing, as well getting assistance with setting up a test project, refer to ecommpay technical support. When testing purchases by using Gate the web service must adhere to the following requirements:

• The we service domain should be registered in the Apple services. For registration contact the ecommpay technical support support@ecommpay.com
• The site supports scripting functionality to start an Apple session according to documentation

Other notes which are specified in the General information table should be taken into account when testing purchases.

When testing payments and operations keep in mind that the test project identifier must be indicated in requests, the interfaces of the emulator of Payment Page and Apple Pay payment forms, the 3‑D Secure authentication page can differ from the production environment. To avoid errors during purchase testing it is recommended to use a payment card which is already registered in the Apple Pay service. This does not influence the processing of real payments by using such cards, but allows to perform full-fledged testing.

Statuses of test payment and operations

The final status of test payments and operations is determined by the amount specified in the request.

Test one-step and two-step purchases:

• 1000 amount to get the success status
• 2000, 5000 or 10001 amount to get the decline status

Test payment card verification:

• 0 amount to get the success status
• any other amount to get the decline status
