Optional memo or note for the payment

Client Account ID to associate with this transaction. When supplied with no recipient details and no ZelleToken, the client account's default Zelle recipient (set via zelle/set-my-recipient) is used; if that client account has no default recipient the request fails. If your account uses contacts (client accounts disabled), the contact's default Zelle recipient is always used and supplying a ZelleToken, EmailAddress or PhoneNumber alongside ContactID is rejected. If your account uses client accounts, the same restriction applies unless third-party client account transactions are enabled, in which case a client account may pay a named recipient — supplying a ZelleToken, EmailAddress or PhoneNumber alongside ClientAccountID is rejected.

Token of a previously stored Zelle recipient (from zelle/link-recipient or zelle/recipients). When supplied, FirstName, LastName, EmailAddress and PhoneNumber must be omitted — the recipient details are taken from the stored recipient.
