lightning-sendinvoice -- Command for send an invoice for an offer


(WARNING: experimental-offers only)

sendinvoice invreq label [amount_msat] [timeout] [quantity]


The sendinvoice RPC command creates and sends an invoice to the
issuer of an invoice_request for it to pay: lightning-invoicerequest(7).

If fetchinvoice-noconnect is not specified in the configuation, it
will connect to the destination in the (currently common!) case where it
cannot find a route which supports option_onion_messages.

invreq is the bolt12 invoice_request string beginning with "lnr1".

label is the unique label to use for this invoice.

amount_msat is optional: it is required if the offer does not specify
an amount at all, or specifies it in a different currency. Otherwise
you may set it (e.g. to provide a tip), and if not it defaults to the
amount contained in the offer (multiplied by quantity if any).

timeout is how many seconds to wait for the offering node to pay the
invoice or return an error, default 90 seconds. This will also be the
timeout on the invoice that is sent.

quantity is optional: it is required if the offer specifies
quantity_max, otherwise it is not allowed.


On success, an object is returned, containing:

  • label (string): unique label supplied at invoice creation
  • description (string): description used in the invoice
  • payment_hash (hash): the hash of the payment_preimage which will prove payment
  • status (string): Whether it's paid, unpaid or unpayable (one of "unpaid", "paid", "expired")
  • expires_at (u64): UNIX timestamp of when it will become / became unpayable
  • created_index (u64): 1-based index indicating order this invoice was created in (added v23.08)
  • amount_msat (msat, optional): the amount required to pay this invoice
  • bolt12 (string, optional): the BOLT12 string
  • updated_index (u64, optional): 1-based index indicating order this invoice was changed (only present if it has changed since creation) (added v23.08)

If status is "paid":

  • pay_index (u64): Unique incrementing index for this payment
  • amount_received_msat (msat): the amount actually received (could be slightly greater than amount_msat, since clients may overpay)
  • paid_at (u64): UNIX timestamp of when it was paid
  • payment_preimage (secret): proof of payment

The following error codes may occur:

  • -1: Catchall nonspecific error.
  • 1002: Offer has expired.
  • 1003: Cannot find a route to the node making the offer.
  • 1004: The node making the offer returned an error message.
  • 1005: We timed out waiting for the invoice to be paid
