Example

{
    "Account": "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn",
    "TransactionType": "PaymentChannelFund",
    "Channel": "C1AE6DDDEEC05CF2978C0BAD6FE302948E9533691DC749DCDD3B9E5992CA6198",
    "Amount" : {
         "currency" : "USD",
         "value" : "1",
         "issuer" : "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn"

Field	JSON Type	[Internal Type][]	Description
Channel	String	Hash256	The unique ID of the channel to fund, as a 64-character hexadecimal string.
Amount	Currency 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.
