Tax integration service

If you have not registered the external service for tax integration:
  1. 1.
    The script below can be used to insert the Tax Calculation Apex class that comes with the package into RegisteredExternalService. To use the script, simply modify the <<storeName>> variable before running.
    // WebStore query values
    String webstoreName = <<storeName>>; // Enter your webstore name
    // ApexClass query values
    String apexClassname = 'DRB2B_CartTaxCalculations';
    String status = 'Active';
    Double ApiVersion = 51.0;
    // RegisteredExternalService insert values
    String registeredProviderType = 'Tax';
    String registeredDevName = 'COMPUTE_TAXES';
    String registeredLabel = registeredDevName;
    // StoreIntegratedService insert values
    String devname = registeredDevName;
    String prefix = registeredProviderType;
    String prefixedName = prefix + '__' + devname;
    // locate webstore
    WebStore webStore = Database.query('SELECT Id FROM WebStore
    WHERE Name = :webstoreName LIMIT 1');
    String webStoreId = webStore.Id;
    System.debug('webStoreId:' + webStoreId);
    // locate apex class Id
    ApexClass apexClass = Database.query('SELECT Id FROM ApexClass
    WHERE Status=:status AND ApiVersion=:apiVersion AND
    Name=:apexClassname LIMIT 1');
    String apexClassId = apexClass.Id;
    System.debug('apexClassId:' + apexClassId);
    // locate apex in RegisteredExternalService
    String registeredIntegrationId = null;
    try {
    RegisteredExternalService registeredExternalService =
    Database.query('SELECT Id FROM RegisteredExternalService
    WHERE ExternalServiceProviderId=:apexClassId AND
    DeveloperName=:registeredDevName AND
    ExternalServiceProviderType=:registeredProviderType LIMIT 1');
    registeredIntegrationId = registeredExternalService.Id;
    System.debug('apex class registration: FOUND '
    + registeredIntegrationId);
    //delete registeredExternalService; // optionally remove
    if needed
    }
    catch (QueryException q) {
    System.debug('apex class registration: MISSING ' + apexClassId);
    insert new RegisteredExternalService(DeveloperName =
    registeredDevName, MasterLabel = registeredLabel,
    ExternalServiceProviderId = apexClassId,
    ExternalServiceProviderType = registeredProviderType);
    RegisteredExternalService registeredExternalService =
    Database.query('SELECT Id FROM RegisteredExternalService WHERE
    ExternalServiceProviderId = :apexClassId LIMIT 1');
    registeredIntegrationId = registeredExternalService.Id;
    System.debug('apex class registration: INSERTED ' +
    registeredIntegrationId);
    }
  2. 2.
    Verify that the Tax Calculation Apex class ID is registered with thesoqlquery below. The ExternalServiceProviderId should match the Tax Calculation Apex Class DRB2B_CartTaxCalculations ID in the org.
Select Id, ExternalServiceProviderId, ExternalServiceProviderType,
DeveloperName From RegisteredExternalService Where
ExternalServiceProviderType = 'Tax'
If you have already registered the external service for tax integration:
  1. 1.
    Execute the below script to update the Tax Integration service to point to the Tax Calculation integration class from the Salesforce Lightning app.
    // Configure Tax Calculation Service
    RegisteredExternalService taxServiceRegistration = [
    SELECT Id
    FROM RegisteredExternalService
    WHERE ExternalServiceProviderType = 'Tax'
    LIMIT 1
    ];
    ApexClass taxCalculationService = [
    SELECT Id
    FROM ApexClass
    WHERE Name = 'DRB2B_CartTaxCalculations'
    LIMIT 1
    ];
    taxServiceRegistration.ExternalServiceProviderId =
    taxCalculationService.Id;update taxServiceRegistration;
  2. 2.
    Verify that the Tax Calculation Apex class ID is registered by making the below soql query. The ExternalServiceProviderId should match the Tax Calculation Apex Class DRB2B_CartTaxCalculations ID in the org.
Select Id, ExternalServiceProviderId, ExternalServiceProviderType,
DeveloperName From RegisteredExternalService Where
ExternalServiceProviderType = 'Tax'

  1. 1.
    Capture the WebStore Id. This will be used in the script in step 4.

NamedCredential namedCredential = [SELECT Id FROM NamedCredential
WHERE DeveloperName = 'Digital_River_API' LIMIT 1];
PaymentGateway paymentGateway = new PaymentGateway(
PaymentGatewayName = 'Digital River Payment Gateway',
MerchantCredentialId = namedCredential.Id,
PaymentGatewayProviderId = paymentGatewayProvider.Id,
Status = 'Active'
);
insert paymentGateway;
List<StoreIntegratedService> storeIntegratedServiceList =
[SELECT Id FROM StoreIntegratedService WHERE ServiceProviderType =
'Payment' Limit 1];
if(null != storeIntegratedServiceList &&
storeIntegratedServiceList.size() > 0) {
StoreIntegratedService storeIntegratedService =
storeIntegratedServiceList.get(0);
storeIntegratedService.Integration = paymentGateway.Id;
update storeIntegratedServiceList;
}
