The smallest unit of Bitcoin. 1 BTC = 100,000,000 satoshis. All Lightning amounts in this API are denominated in satoshis.

The standard encoding format for Lightning invoices. A BOLT11 string contains the destination, amount, description, and expiry — everything a wallet needs to make a payment.

A 64-character hex string that uniquely identifies a Lightning payment. It is derived from the payment preimage and is used to verify that a payment was completed.

A 64-character hex secret that proves a payment was successfully received. When a payment settles, the receiver reveals the preimage to the sender as proof of payment.

A payment request generated by the receiver. It encodes the amount, description, expiry, and destination so the sender knows exactly what to pay.

Whether the invoice is 'incoming' (you created it to receive payment) or 'outgoing' (you paid someone else's invoice).

A unique string you provide to ensure the same request is not processed twice. If you retry a request with the same reference, the API returns the original result instead of creating a duplicate.

The customer UUID this invoice belongs to. Useful for associating payments with specific users in your system.

The invoice amount in satoshis. Must be between 1 and 20,000,000 sats (0.2 BTC). This is the exact amount the payer will be asked to send.

A human-readable description of what the payment is for (e.g., 'Payment for order #123'). This is displayed in the payer's wallet.

How long the invoice remains valid, in seconds. Default: 86400 (24 hours). After expiry, the invoice can no longer be paid.

A unique idempotency key for this request. If you send the same reference twice, the API returns the original invoice instead of creating a duplicate.

A unique UUID assigned to this invoice. Use this to retrieve or reference the invoice later.

A 64-character hex string that uniquely identifies this payment on the Lightning Network. Used to verify payment completion.

The BOLT11 invoice string. Share this with the payer — they paste it into their Lightning wallet to pay.

The invoice amount in satoshis, returned as a string to preserve precision on large values.

The description attached to the invoice.

Current state of the invoice: 'pending' (awaiting payment), 'paid' (settled), or 'expired' (no longer valid).

ISO 8601 timestamp when the invoice will expire and become unpayable.

ISO 8601 timestamp when the invoice was created.

A BOLT11-encoded Lightning invoice string. This is the payment request you want to inspect.

The unique hash identifying this payment. Used to track and verify the payment across the Lightning Network.

The public key of the Lightning node that will receive the payment. This is a 66-character hex string unique to each node.

The invoice amount in satoshis.

The invoice amount in millisatoshis (1 sat = 1000 msat). Used for more precise routing calculations.

The human-readable memo attached to the invoice by the creator.

Unix timestamp (seconds) when the invoice expires.

Whether the invoice has already expired. If true, the invoice can no longer be paid.

The BOLT11 invoice string to pay. Must be a valid Lightning invoice.

The hash that identifies this payment on the Lightning Network.

The public key of the destination node that will receive the payment.

The amount to be sent in satoshis.

The estimated routing fee in satoshis.

The total cost of the payment (amount + fee) in satoshis.

The description embedded in the Lightning invoice.

Unix timestamp when the invoice expires.

Whether the invoice has already expired.

Whether a valid route to the destination was found. If false, the payment cannot be completed.

The BOLT11 invoice string to pay. Must be valid and unexpired.

Unique idempotency key. Retrying with the same reference returns the original payment and will not debit the wallet twice.

Customer UUID that initiated this payment, for attribution on the transaction record.

Maximum routing fee you will tolerate, in satoshis. The payment aborts before sending if the estimated fee exceeds this value. Omit or set to 0 for no cap.

Top-level flag indicating the payment was sent successfully.

Human-readable status message.

Unique identifier for this payment record.

64-character hex hash identifying this payment on the Lightning Network.

The 64-character hex preimage — your cryptographic proof that the recipient received the funds. Store this for dispute resolution; it is unforgeable evidence of settlement.

Amount sent in satoshis, returned as a string.

Actual routing fee charged, in satoshis, returned as a string. Deducted from your wallet in addition to amount_sat.

Payment status: 'paid' (settled), 'pending' (in-flight), or 'failed' (could not route or settle).

RFC-3339 timestamp when the payment was created.

The idempotency key you supplied, echoed back.

Transaction record ID linking this payment to your ledger. Usually identical to data.id.

Unique request identifier for support and tracing.

Server time when the response was generated.

Top-level flag indicating the invoice was retrieved.

Human-readable status message.

The unique identifier of the invoice.

64-character hex hash uniquely identifying this payment on the Lightning Network.

The BOLT11 invoice string.

Payment preimage — proof of payment. Empty string while status is 'pending'; populated once the invoice settles.

Invoice amount in satoshis, returned as a string to preserve precision.

Invoice amount in millisatoshis (1 sat = 1000 msat), returned as a string.

Routing fee in satoshis. Always '0' for incoming invoices you created.

Routing fee in millisatoshis. Always '0' for incoming invoices you created.

The description attached to the invoice.

Current state: 'pending', 'paid', 'expired', or 'failed'.

'incoming' if you created this invoice to receive a payment, 'outgoing' if you paid someone else's invoice.

The ID of the company that owns this invoice.

The customer associated with the invoice, if provided during creation.

The idempotency key supplied at creation, echoed back.

Unix epoch seconds (as a string) when the invoice expires — e.g. '1774192723'. Differs from Create, which returns RFC-3339.

RFC-3339 timestamp when the invoice was created.

RFC-3339 timestamp of the last update (e.g. when status flipped to 'paid'). Empty string if the invoice has never been updated.

Unique request identifier for support and tracing.

Server time when the response was generated.

Page number to retrieve. Default: 1.

Number of results per page. Default: 20, maximum: 100.

Filter by invoice status. Accepted values: 'pending', 'paid', 'expired', 'failed'.

Filter by direction. 'incoming' for invoices you created to receive payment, 'outgoing' for invoices you paid.

Array of invoice records. Each entry carries the full Get Invoice shape plus the millisatoshi/fee fields: payment_hash, request, preimage, amount_sat, amount_msat, fee_sat, fee_msat, description, status, direction, company_id, customer_id, reference, expires_at, created_at, updated_at.

Total number of invoices matching the filters across all pages. Returned as a string.

Current page number (1-indexed).

Number of invoices returned per page.

Server time when the response was generated.
