lightning-waitanyinvoice -- Command for waiting for payments

SYNOPSIS

waitanyinvoice [lastpay_index] [timeout]

DESCRIPTION

The waitanyinvoice RPC command waits until an invoice is paid, then returns a single entry as per listinvoices. It will not return for any invoices paid prior to or including the lastpay_index.

This is usually called iteratively: once with no arguments, then repeatedly with the returned pay_index entry. This ensures that no paid invoice is missed. The pay_index is a monotonically-increasing number assigned to an invoice when it gets paid. The first valid pay_index is 1.

• lastpay_index (u64, optional): Ignores any invoices paid prior to or including this index. 0 is equivalent to not specifying and negative value is invalid.
• timeout (u64, optional): If specified, wait at most that number of seconds, which must be an integer. If the specified timeout is reached, this command will return with an error. You can specify this to 0 so that waitanyinvoice will return immediately with an error if no pending invoice is available yet. If unspecified, this command will wait indefinitely.

RETURN VALUE

On success, an object is returned, containing:

• label (string): Unique label supplied at invoice creation.
• payment_hash (hash): The hash of the payment_preimage which will prove payment.
• status (string) (one of "paid", "expired"): Whether it's paid or 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)
• description (string, optional): Description used in the invoice.
• amount_msat (msat, optional): The amount required to pay this invoice.
• bolt11 (string, optional): The BOLT11 string (always present unless bolt12 is).
• bolt12 (string, optional): The BOLT12 string (always present unless bolt11 is).
• 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.
• paid_outpoint (object, optional): Outpoint this invoice was paid with. (added v23.11):
  • txid (txid): ID of the transaction that paid the invoice. (added v23.11)
  • outnum (u32): The 0-based output number of the transaction that paid the invoice. (added v23.11)

ERRORS

The following error codes may occur:

• 904: The timeout was reached without an invoice being paid.
