VIES VAT number validation PHP sdk REST component description.

AbstractVatNumberValidationRestService - is an abstract class that implements the interface https://github.com/rocketfellows/vies-vat-validation-php-sdk-interface and is intended for sending a request for VAT validation using the REST web service, processing response/faults and returning an object of type validation result.

VatNumberValidationRestService - is an inheritor of the AbstractVatNumberValidationRestService class, configured to send a request to the production api endpoint by url https://ec.europa.eu/taxation_customs/vies/rest-api/check-vat-number.

VatNumberValidationRestTestService - is an inheritor of the AbstractVatNumberValidationRestService class, configured to send a request to the test api endpoint by url https://ec.europa.eu/taxation_customs/vies/rest-api/check-vat-test-service.

VatNumberValidationRestExpansibleService - is an inheritor of the AbstractVatNumberValidationRestService class, configured to send a request to the service according to url, passed through the class constructor (customizable service).

For creating vat number validation result this component is using factory rocketfellows\ViesVatValidationInterface\VatNumberValidationResultFactory from interface package https://github.com/rocketfellows/vies-vat-validation-php-sdk-interface. According to factory, if any of required response attributes is missing, then validation process will throw special exceptions:

• CountryCodeAttributeNotFoundException - exception thrown if while creating instance of VatNumberValidationResult country code attribute not found.
• RequestDateAttributeNotFoundException - exception thrown if while creating instance of VatNumberValidationResult request date attribute not found.
• ValidationFlagAttributeNotFoundException - exception thrown if while creating instance of VatNumberValidationResult validation flag attribute not found.
• VatNumberAttributeNotFoundException - exception thrown if while creating instance of VatNumberValidationResult vat number attribute not found.
• VatOwnerAddressAttributeNotFoundException - exception thrown if while creating instance of VatNumberValidationResult vat owner address attribute not found.
• VatOwnerNameAttributeNotFoundException - exception thrown if while creating instance of VatNumberValidationResult vat owner name attribute not found.
