LIGHTNING-HOOK-INVOICE_PAYMENT(7)	       LIGHTNING-HOOK-INVOICE_PAYMENT(7)

NAME
     invoice_payment -- Hook fired when a payment for an invoice is received

DESCRIPTION
     The  invoice_payment  hook is called whenever a valid payment for an unpaid
     invoice has arrived.

     The hook is deliberately sparse. Plugins can use listinvoices  to	retrieve
     additional information.

     The  plugin can: - accept the payment by returning {"result": "continue"} -
     reject the payment with a generic error using {"result": "reject"} - reject
     the payment with a custom BOLT 4 failure message using the  failure_message
     field

     If  failure_message  is provided, the payment will be failed with that mes-
     sage.  If result is "reject" and no failure_message is provided,  the  pay-
     ment fails with incorrect_or_unknown_payment_details.  failure_message must
     NOT be provided when result is "continue".

     Before  version 23.11 the msat field was encoded as a string with an 'msat'
     suffix.

HOOK PAYLOAD
     *	payment (object): Basic  payment  information.	 Additional  TLV-derived
	fields may be included when running in developer mode.:
	*  label (string): Unique label identifying the invoice.
	*  preimage (secret): The payment preimage.
	*  msat (msat): Amount paid in millisatoshis.

HOOK RETURN
     *	result (string) (one of "continue", "reject"): Controls whether the pay-
	ment is accepted or rejected.  "continue" accepts the payment.	"reject"
	fails the payment.
     *	failure_message  (hex, optional): Optional BOLT 4 failure message.  Used
	to provide a specific failure reason when rejecting the payment.

     If result is present, and result is "reject": - failure_message  (hex,  op-
     tional)
