LIGHTNING-OFFER(7) LIGHTNING-OFFER(7) NAME offer -- Command for accepting payments SYNOPSIS offer amount [description] [issuer] [label] [quantity_max] [ab- solute_expiry] [recurrence] [recurrence_base] [recurrence_paywindow] [recurrence_limit] [single_use] [proportional_amount] [optional_recur- rence] DESCRIPTION The offer RPC command creates an offer (or returns an existing one), which is a precursor to creating one or more invoices. It automatically enables the processing of an incoming invoice_request, and issuing of invoices. Note that for making an offer to pay someone else, see lightning- in- voicerequest(7). • amount (one of): 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 dec- imal places ending in sat, or a number with 1 to 11 decimal places ending in btc. It can also have an ISO 4217 postfix (e.g. USD), in which case currency conversion will need to be done for the invoice itself. A plugin is needed which provides the currencyconvert API for this currency, otherwise the offer creation will fail.: • (msat_or_any) • (currency) • description (string, optional): A short description of purpose of the offer, e.g. coffee. This value is encoded into the resulting of- fer and is viewable by anyone you expose this offer to. It must be UTF-8, and cannot use \u JSON escape codes. • issuer (string, optional): Who is issuing this offer (i.e. you) if appropriate. • label (string, optional): An internal-use name for the offer, which can be any UTF-8 string. This is NOT encoded in the offer not sent to the issuer. • quantity_max (u64, optional): Invoice can specify more than one of the items up (and including) this maximum: 0 is a special value meaning no maximuim. The amount for the invoice will need to be mul- tiplied accordingly. This is encoded in the offer. • absolute_expiry (u64, optional): Time the offer is valid until,in seconds since the first day of 1970 UTC. If not set, the offer re- mains valid (though it can be deactivated by the issuer of course). This is encoded in the offer. • recurrence (string, optional): An invoice is expected at regular in- tervals. The argument is a positive number followed by one of sec- onds, minutes, hours, days, weeks, or months (variants without the trailing s are also permitted). This is encoded in the offer. The semantics of recurrence is fairly predictable, but fully documented in BOLT 12. e.g. 4weeks. • recurrence_base (integer, optional): Time in seconds since the first day of 1970 UTC. This indicates when the first period begins; with- out this, the recurrence periods start from the first invoice. • recurrence_paywindow (string, optional): Argument of form -time+time. The first time is the number of seconds before the start of a period in which an invoice and payment is valid, the second time is the number of seconds after the start of the period. For ex- ample -604800+86400 means you can fetch an pay the invoice 4 weeks before the given period starts, and up to 1 day afterwards. The op- tional % indicates that the amount of the invoice will be scaled by the time remaining in the period. This is encoded in the offer. The default is that payment is allowed during the current and previous periods. • recurrence_limit (u32, optional): To indicate the maximum period which exists. eg. 12 means there are 13 periods, from 0 to 12 inclu- sive. This is encoded in the offer. • single_use (boolean, optional): Indicates that the offer is only valid once; we may issue multiple invoices, but as soon as one is paid all other invoices will be expired (i.e. only one person can pay this offer). The default is False. • proportional_amount (boolean, optional): Payment will be charged for the initial period proportional to the amount remaining (only makes sense if recurrence_base is specified) (added v25.09) • optional_recurrence (boolean, optional): Make recurrence optional, for backwards compatibility (older payers will only pay once). (added v25.09) RETURN VALUE On success, an object is returned, containing: • offer_id (hash): The id of this offer (merkle hash of non-signature fields). • active (boolean) (always true): Whether this can still be used. • single_use (boolean): Whether this expires as soon as it's paid (re- flects the single_use parameter). • bolt12 (string): The bolt12 encoding of the offer. • used (boolean): True if an associated invoice has been paid. • created (boolean): False if the offer already existed. • label (string, optional): The (optional) user-specified label. ERRORS On failure, an error is returned and no offer is created. If the light- ning process fails before responding, the caller should use lightning- listoffers(7) to query whether this offer was created or not. If the offer already existed, and is still active, that is returned; if it's not active then this call fails. • -1: Catchall nonspecific error. • 1000: Offer with this offer_id already exists (but is not active).
