Add additional Amount to an open payment channel, and optionally update the expiration time of the channel. Only the source address of the channel can use this transaction.
Added by the [PayChan amendment][].
Channel
String
Hash256
The unique ID of the channel to fund, as a 64-character hexadecimal string.
Amount
Amount
Amount to add to the channel. Must be a positive amount.
Expiration
Number
UInt32
(Optional) New Expiration time to set for the channel, in [seconds since the Ripple Epoch][]. This must be later than either the current time plus the SettleDelay of the channel, or the existing Expiration of the channel. After the Expiration time, any transaction that would access the channel closes the channel without taking its normal action. Any unspent Amount is returned to the source address when the channel closes. (Expiration is separate from the channel's immutable CancelAfter time.) For more information, see the PayChannel ledger object type.

tecNO_PERMISSION

temBAD_EXPIRATION
