Verification

Make sure that the following modules have been installed:

MODULE EXPECTED DIRECTORY
CheckoutRestApi vendor/spryker/checkout-rest-api
OrderPaymentsRestApi vendor/spryker/order-payments-rest-api
SalesOrderThresholdsRestApi vendor/spryker/sales-order-thresholds-rest-api

2) Set up configuration

  1. Add the following configuration to your project:
CONFIGURATION SPECIFICATION NAMESPACE
CheckoutRestApiConfig::shouldExecuteQuotePostRecalculationPlugins() Defines if a stack of QuotePostRecalculatePluginStrategyInterface plugins should be executed after quote recalculation. Pyz\Zed\CheckoutRestApi
CheckoutRestApiConfig::getRequiredCustomerRequestDataForGuestCheckout() Returns the customer data fields required for checkout as a guest user. Pyz\Glue\CheckoutRestApi

src/Pyz/Glue/CheckoutRestApi/CheckoutRestApiConfig.php

<?php

namespace Pyz\Zed\CheckoutRestApi;

use Spryker\Zed\CheckoutRestApi\CheckoutRestApiConfig as SprykerCheckoutRestApiConfig;

class CheckoutRestApiConfig extends SprykerCheckoutRestApiConfig
{
    /**
     * @return bool
     */
    public function shouldExecuteQuotePostRecalculationPlugins(): bool
    {
        return false;
    }
}

src/Pyz/Glue/CheckoutRestApi/CheckoutRestApiConfig.php

<?php

namespace Pyz\Glue\CheckoutRestApi;

use Generated\Shared\Transfer\RestCustomerTransfer;
use Spryker\Glue\CheckoutRestApi\CheckoutRestApiConfig as SprykerCheckoutRestApiConfig;

class CheckoutRestApiConfig extends SprykerCheckoutRestApiConfig
{
    /**
     * @return list<string>
     */
    public function getRequiredCustomerRequestDataForGuestCheckout(): array
    {
        return array_merge(parent::getRequiredCustomerRequestDataForGuestCheckout(), [
            RestCustomerTransfer::FIRST_NAME,
            RestCustomerTransfer::LAST_NAME,
        ]);
    }
}
  1. Add all the payment methods available in the shop to CheckoutRestApiConfig—for example:
src/Pyz/Glue/CheckoutRestApi/CheckoutRestApiConfig.php 
<?php

namespace Pyz\Glue\CheckoutRestApi;

use Spryker\Glue\CheckoutRestApi\CheckoutRestApiConfig as SprykerCheckoutRestApiConfig;

class CheckoutRestApiConfig extends SprykerCheckoutRestApiConfig
{
    protected const PAYMENT_METHOD_REQUIRED_FIELDS = [
        'dummyPaymentInvoice' => ['dummyPaymentInvoice.dateOfBirth'],
        'dummyPaymentCreditCard' => [
            'dummyPaymentCreditCard.cardType',
            'dummyPaymentCreditCard.cardNumber',
            'dummyPaymentCreditCard.nameOnCard',
            'dummyPaymentCreditCard.cardExpiresMonth',
            'dummyPaymentCreditCard.cardExpiresYear',
            'dummyPaymentCreditCard.cardSecurityCode',
        ],
    ];

    /**
     * @uses \Spryker\Shared\DummyPayment\DummyPaymentConfig::PROVIDER_NAME
     */
    protected const DUMMY_PAYMENT_PROVIDER_NAME = 'DummyPayment';

    /**
     * @uses \Spryker\Shared\DummyPayment\DummyPaymentConfig::PAYMENT_METHOD_NAME_INVOICE
     */
    protected const DUMMY_PAYMENT_PAYMENT_METHOD_NAME_INVOICE = 'Invoice';

    /**
     * @uses \Spryker\Shared\DummyPayment\DummyPaymentConfig::PAYMENT_METHOD_NAME_CREDIT_CARD
     */
    protected const DUMMY_PAYMENT_PAYMENT_METHOD_NAME_CREDIT_CARD = 'Credit Card';

    /**
     * @uses \Spryker\Shared\DummyPayment\DummyPaymentConfig::PAYMENT_METHOD_INVOICE
     */
    protected const PAYMENT_METHOD_INVOICE = 'dummyPaymentInvoice';

    /**
     * @uses \Spryker\Shared\DummyPayment\DummyPaymentConfig::PAYMENT_METHOD_CREDIT_CARD
     */
    protected const PAYMENT_METHOD_CREDIT_CARD = 'dummyPaymentCreditCard';

    protected const IS_PAYMENT_PROVIDER_METHOD_TO_STATE_MACHINE_MAPPING_ENABLED = false;

    /**
     * @return array
     */
    public function getPaymentProviderMethodToStateMachineMapping(): array
    {
        return [
            static::DUMMY_PAYMENT_PROVIDER_NAME => [
                static::DUMMY_PAYMENT_PAYMENT_METHOD_NAME_CREDIT_CARD => static::PAYMENT_METHOD_CREDIT_CARD,
                static::DUMMY_PAYMENT_PAYMENT_METHOD_NAME_INVOICE => static::PAYMENT_METHOD_INVOICE,
            ],
        ];
    }

    /**
     * @return bool
     */
    public function isShipmentMethodsMappedToAttributes(): bool
    {
        return false;
    }

    /**
     * @return bool
     */
    public function isPaymentProvidersMappedToAttributes(): bool
    {
        return false;
    }

    /**
     * @return bool
     */
    public function isAddressesMappedToAttributes(): bool
    {
        return false;
    }
}
Info

If CheckoutRestApiConfig::IS_PAYMENT_PROVIDER_METHOD_TO_STATE_MACHINE_MAPPING_ENABLED is true, make sure that the payment methods and providers of your shop are configured in CheckoutRestApiConfig::getPaymentProviderMethodToStateMachineMapping().

Setting CheckoutRestApiConfig::IS_PAYMENT_PROVIDER_METHOD_TO_STATE_MACHINE_MAPPING_ENABLED to false ignores the Glue API level configuration. Subsequently, the checkout-data endpoint returns all the payment methods.

“Verification”

For the checkout-data endpoint to keep returning shipment methods, keep Pyz\Glue\CheckoutRestApi\CheckoutRestApiConfig::isShipmentMethodsMappedToAttributes() set to true.

If Pyz\Glue\CheckoutRestApi\CheckoutRestApiConfig::isShipmentMethodsMappedToAttributes() is true, make sure the shipping method attributes are returned in the shipmentMethods after sending the POST https://glue.mysprykershop.com/checkout-data request:

            new GuestCartByRestCheckoutDataResourceRelationshipPlugin(),
        );

        return $resourceRelationshipCollection;
    }
}
Verification

Make sure that the following plugins are activated:

PLUGIN TEST
CheckoutDataResourcePlugin Check if you get a valid response by sending the POST https://glue.mysprykershop.com/checkout-data request.
CheckoutResourcePlugin Check if you get a valid response by sending the POST https://glue.mysprykershop.com/checkout request.
OrderRelationshipByOrderReferencePlugin Check if you get order information from the orders resource by sending the POST https://glue.mysprykershop.com/checkout?include=orders request.
CartByRestCheckoutDataResourceRelationshipPlugin Check if you get cart data as a relationship from the checkout-data resource by sending the POST https://glue.mysprykershop.com/checkout-data?include=carts request.
GuestCartByRestCheckoutDataResourceRelationshipPlugin Check if you get guest cart data as a relationship from the checkout-data resource by sending the POST https://glue.mysprykershop.com/checkout?include=guest-carts request.

To make sure that OrderPaymentsResourceRoutePlugin is activated, check if you get a valid response by sending the following request:

https://glue.mysprykershop.com/order-payments

{
    "data": {
        "type": "order-payments",
        "attributes": {
            "paymentIdentifier": {{paymentIdentifier}},
            "dataPayload": {{dataPayload}}
        }
    }
}

To ensure that CartByRestCheckoutDataResourceRelationshipPlugin is set up correctly, do the following:

  1. Send a request with an authorization token to a checkout-data endpoint with carts relation—for example, send the POST https://glue.mysprykershop.com/checkout-data?include=carts request with the request body:
{"data":
    {"type": "checkout-data",
      "attributes":
      {
        "idCart": "_cart_id",
        "shipment": {
          "idShipmentMethod": 1
        }
      }
    }
}
  1. Check that the cart data is returned as a relationship and contains shipmentTotal in cart totals:
{
  "data": {
    "type": "checkout-data",
    ...
    },
    ...
    "relationships": {
      "carts": {
        "data": [
          {
            "type": "carts",
            "id": "_cart_id"
          }
        ]
      }
    }
  },
  "included": [
    {
      "type": "carts",
      "id": "_cart_id",
      "attributes": {
        ...
        "totals": {
        ...
          "shipmentTotal": ...
        }
      }
    }
  ]
}

Ensure that GuestCartByRestCheckoutDataResourceRelationshipPlugin is set up correctly:

  1. Send a request with an anonymous customer ID to a checkout-data endpoint with guest-carts relation—for example, send the POST https://glue.mysprykershop.com/checkout-data?include=guest-carts request with the request body:
{"data":
    {"type": "checkout-data",
      "attributes":
      {
        "idCart": "_cart_id",
        "shipment": {
          "idShipmentMethod": 1
        }
      }
    }
}
  1. Check that the guest cart data is returned as a relationship and contains shipmentTotal in cart totals:
{
  "data": {
    "type": "checkout-data",
    ...
    },
    ...
    "relationships": {
      "guest-carts": {
        "data": [
          {
            "type": "guest-carts",
            "id": "_cart_id"
          }
        ]
      }
    }
  },
  "included": [
    {
      "type": "guest-carts",
      "id": "_cart_id",
      "attributes": {
        ...
        "totals": {
        ...
          "shipmentTotal": ...
        }
      }
    }
  ]
}

Configure mapping

Mappers must be configured on a project level to map the data from the request into QuoteTransfer:

PLUGIN SPECIFICATION PREREQUISITES NAMESPACE
CustomerQuoteMapperPlugin Adds a mapper that maps customer information to QuoteTransfer. None Spryker\Zed\CustomersRestApi\Communication\Plugin\CheckoutRestApi
AddressQuoteMapperPlugin Adds a mapper that maps billing and shipping address information to QuoteTransfer. None Spryker\Zed\CustomersRestApi\Communication\Plugin\CheckoutRestApi
