Methods

ValidateCredentialsList(object, string, string, bool, int)

Validates a list of credentials. Two list shapes are supported:

• When isStringID is true, the list must contain hex object-IDs (64 hex characters each). This is the format used by the CredentialIDs field on Payment, EscrowFinish, AccountDelete and PaymentChannelClaim.
• When isStringID is false, the list must contain wrapped credential objects of the form { Credential: { Issuer, CredentialType } }. This is the format used by the AuthorizeCredentials / UnauthorizeCredentials fields on the DepositPreauth transaction.

Declaration

public static void ValidateCredentialsList(object credentials, string txType, string fieldName, bool isStringID, int maxLength = 8)

Parameters

Type	Name	Description
object	credentials	The raw list value extracted from the transaction dictionary.
string	txType	The transaction type name used for error messages (e.g. "Payment").
string	fieldName	The field name used for error messages (e.g. "CredentialIDs").
bool	isStringID	Determines the expected element shape (see above).
int	maxLength	Maximum allowed list length. Defaults to MaxCredentialsListLength.

Exceptions

Type	Condition
