LIGHTNING-LISTHTLCS(7) LIGHTNING-LISTHTLCS(7) NAME listhtlcs -- Command for querying HTLCs SYNOPSIS listhtlcs [id] [index] [start] [limit] DESCRIPTION The listhtlcs RPC command gets all HTLCs (which, generally, we remember for as long as a channel is open, even if they've completed long ago). • id (string, optional): A short channel id (e.g. 1x2x3) or full 64-byte hex channel id, it will only list htlcs for that channel (which must be known). • index (string, optional) (one of "created", "updated"): This con- trols the ordering of results. The default is created. (added v25.05) • start (u64, optional): If index is specified, start may be specified to start from that value, which is generally returned from light- ning-wait(7). (added v25.05) • limit (u32, optional): If index is specified, limit can be used to specify the maximum number of entries to return. (added v25.05) RETURN VALUE On success, an object containing htlcs is returned. It is an array of objects, where each object contains: • short_channel_id (short_channel_id): The channel that contains/con- tained the HTLC. • created_index (u64): 1-based index indicating order this htlc was created in. (added v25.05) • id (u64): The unique, incrementing HTLC id the creator gave this. • expiry (u32): The block number where this HTLC expires/expired. • amount_msat (msat): The value of the HTLC. • direction (string) (one of "out", "in"): Out if we offered this to the peer, in if they offered it. • payment_hash (hash): Payment hash sought by HTLC. • state (string) (one of "SENT_ADD_HTLC", "SENT_ADD_COMMIT", "RCVD_ADD_REVOCATION", "RCVD_ADD_ACK_COMMIT", "SENT_ADD_ACK_REVOCA- TION", "RCVD_REMOVE_HTLC", "RCVD_REMOVE_COMMIT", "SENT_REMOVE_REVO- CATION", "SENT_REMOVE_ACK_COMMIT", "RCVD_REMOVE_ACK_REVOCATION", "RCVD_ADD_HTLC", "RCVD_ADD_COMMIT", "SENT_ADD_REVOCATION", "SENT_ADD_ACK_COMMIT", "RCVD_ADD_ACK_REVOCATION", "SENT_RE- MOVE_HTLC", "SENT_REMOVE_COMMIT", "RCVD_REMOVE_REVOCATION", "RCVD_REMOVE_ACK_COMMIT", "SENT_REMOVE_ACK_REVOCATION"): The first 10 states are for in, the next 10 are for out. • updated_index (u64, optional): 1-based index indicating order this htlc was changed (only present if it has changed since creation).
