NAME

lightning-decodepay -- Command for decoding a bolt11 string (low-level)

SYNOPSIS

decodepay bolt11 [description]

DESCRIPTION

Command added in v23.05.

WARNING: deprecated: use decode which also handles bolt12.

The decodepay RPC command checks and parses a bolt11 string as specified by the BOLT 11 specification.

bolt11 (string): Bolt11 invoice to decode.
description (string, optional): Description of the invoice to decode.

RETURN VALUE

On success, an object is returned, containing:

currency (string): The BIP173 name for the currency.
created_at (u64): The UNIX-style timestamp of the invoice.
expiry (u64): The number of seconds this is valid after timestamp.
payee (pubkey): The public key of the recipient.
payment_hash (hash): The hash of the payment_preimage.
signature (signature): Signature of the payee on this invoice.
min_final_cltv_expiry (u32): The minimum CLTV delay for the final node.
amount_msat (msat, optional): Amount the invoice asked for.
description (string, optional): The description of the purpose of the purchase.
description_hash (hash, optional): The hash of the description, in place of description.
payment_secret (hash, optional): The secret to hand to the payee node.
features (hex, optional): The features bitmap for this invoice.
payment_metadata (hex, optional): The payment_metadata to put in the payment.
fallbacks (array of objects, optional): Onchain addresses.:

type (string) (one of "P2PKH", "P2SH", "P2WPKH", "P2WSH", "P2TR"): The address type (if known).
hex (hex): Raw encoded address.
addr (string, optional): The address in appropriate format for type.

•: routes (array of arrays, optional): Route hints to the payee.:

(array of objects): Hops in the route.
pubkey (pubkey): The public key of the node.
short_channel_id (short_channel_id): A channel to the next peer.
fee_base_msat (msat): The base fee for payments.
fee_proportional_millionths (u32): The parts-per-million fee for payments.
cltv_expiry_delta (u32): The CLTV delta across this hop.

•: extra (array of objects, optional): Any extra fields we didn't know how to parse.:

tag (string) (always 1 characters): The bech32 letter which identifies this field.
data (string): The bech32 data for this field.

Technically, the description field is optional if a description_hash field is given, but in this case decodepay will only succeed if the optional description field is passed and matches the description_hash. In practice, these are currently unused.
