satoshi is the amount to be withdrawn from the internal wallet (expressed, as name suggests, in satoshi). The string all can be used to specify withdrawal of all available funds. Otherwise, it is in satoshi precision; it can be a whole number, a whole number ending in sat, a whole number ending in 000msat, or a number with 1 to 8 decimal places ending in btc.
feerate is an optional feerate to use. It can be one of the strings urgent (aim for next block), normal (next 4 blocks or so) or slow (next 100 blocks or so) to use lightningd's internal estimates: normal is the default.
Otherwise, feerate is a number, with an optional suffix: perkw means the number is interpreted as satoshi-per-kilosipa (weight), and perkb means it is interpreted bitcoind-style as satoshi-per-kilobyte. Omitting the suffix is equivalent to perkb.
minconf specifies the minimum number of confirmations that used outputs should have. Default is 1.

On failure, an error is reported and the withdrawal transaction is not created.
The following error codes may occur:
