lightning-offerout -- Command for offering payments
SYNOPSIS
(WARNING: experimental-offers only)
offerout amount description [vendor] [label] [absolute_expiry] [refund_for]
DESCRIPTION
The offerout RPC command creates an offer, which is a request to
send an invoice for us to pay (technically, this is referred to as a
send_invoice offer to distinguish a normal lightningd-offer(7)
offer). It automatically enables the accepting and payment of
corresponding invoice message (we will only pay once, however!).
The amount parameter can be the string "any", which creates an offer that can be paid with any amount (e.g. a donation). Otherwise it can be a positive value in millisatoshi precision; it can be a whole number, or a whole number ending in msat or sat, or a number with three decimal places ending in sat, or a number with 1 to 11 decimal places ending in btc.
The description is a short description of purpose of the offer, e.g. withdrawl from ATM. This value is encoded into the resulting offer and is viewable by anyone you expose this offer to. It must be UTF-8, and cannot use \u JSON escape codes.
The vendor is another (optional) field exposed in the offer, and reflects who is issuing this offer (i.e. you) if appropriate.
The label field is an internal-use name for the offer, which can be any UTF-8 string.
The absolute_expiry is optionally the time the offer is valid until, in seconds since the first day of 1970 UTC. If not set, the offer remains valid (though it can be deactivated by the issuer of course). This is encoded in the offer.
refund_for is a previous (paid) invoice of ours. The
payment_preimage of this is encoded in the offer, and redemption
requires that the invoice we receive contains a valid signature using
that previous payer_key.
RETURN VALUE
On success, an object as follows is returned:
- offer_id: the hash of the offer.
- active: true
- single_use: true
- bolt12: the bolt12 offer, starting with "lno1"
Optionally:
- label: the user-specified label.
On failure, an error is returned and no offer is created. If the lightning process fails before responding, the caller should use lightning-listoffers(7) to query whether this offer was created or not.
The following error codes may occur:
- -1: Catchall nonspecific error.
- 1000: Offer with this offer_id already exists.
NOTES
The specification allows quantity, recurrence and alternate currencies on
offers which contain send_invoice, but these are not implemented here.
We could also allow multi-use offers, but usually you're only offering to send money once.
