Types

type AVSResponse

type AVSResponse int

AVSResponse represents a possible Address Verification System response.

const (

	AVSResponseSkipped                        // Verification was not performed for this transaction.

	AVSResponseZip9MatchAddressMatch     // 9-digit ZIP matches, street address matches.

	AVSResponseZip5MatchAddressMatch     // 5-digit ZIP matches, street address matches.
	AVSResponseZip5MatchAddressNoMatch   // 5-digit ZIP matches, street address doesn't match.
	AVSresponseZipMatchAddressMatch      // 5 or 9 digit ZIP matches, street address matches.
	AVSResponseZipNoMatchAddressMatch    // ZIP doesn't match, street address matches.

	AVSResponseNonUsZipUnverifiedAddressMatch // (Non U.S. cards) ZIP unverified, street address matches.

	AVSResponseNameNoMatch                       // Cardholder's name doesn't match.
	AVSResponseNameNoMatchAddressMatch           // Cardholder's name doesn't match, street address matches.
	AVSResponseNameMatchZipMatchAddressNoMatch   // Cardholder's name and ZIP match, street address doesn't match.
	AVSResponseNameMatchZipNoMatchAddressMatch   // Cardholder's name and street address match, ZIP doesn't match.
