Parameters

Field	Type	Required	Default	Description
`limit`	`number`	No	`20`	Number of invoices per page (max 100)
`offset`	`number`	No	`0`	Number of invoices to skip
`status`	`string`	No	—	Filter by status: `OPEN`, `PAYING`, `PAID`, `EXPIRED`, `CANCELED`

Pagination

Results are ordered newest-first. Use offset and limit to page through results:

1 let offset = 0;
2 const limit = 20;
3 const allInvoices = [];
4 
5 while (true) {
6   const { result } = await gwop.invoices.list({ limit, offset });
7   allInvoices.push(...result.invoices);
8 
9   if (!result.pagination.hasMore) break;
10   offset += limit;
11 }

The pagination object tells you where you are:

Field	Type	Description
`total`	`number`	Total invoices matching the filter
`limit`	`number`	Page size used
`offset`	`number`	Current offset
`hasMore`	`boolean`	`true` if more pages exist

Filter by status

Pass status to return only invoices in a specific state:

1 // Get all paid invoices
2 const { result: paid } = await gwop.invoices.list({ status: "PAID" });
3 
4 // Get open invoices (awaiting payment)
5 const { result: open } = await gwop.invoices.list({ status: "OPEN" });

Valid statuses:

Status	Meaning
`OPEN`	Awaiting payment
`PAYING`	Payment detected, confirming on-chain
`PAID`	Payment confirmed and settled
`EXPIRED`	Invoice TTL reached without payment
`CANCELED`	Merchant canceled the invoice

Invoice list item shape

Each item in the invoices array is a summary — lighter than the full invoice from get().

Field	Type	Present	Description
`id`	`string`	Always	Merchant-side UUID
`publicInvoiceId`	`string`	Always	Payer-facing `inv_*` identifier
`status`	`string`	Always	Current status
`amountUsdc`	`number`	Always	Total amount including fees (6 decimals)
`currency`	`string`	Always	Always `"USDC"`
`description`	`string`	If set	Invoice description
`metadata`	`object`	If set	Includes fee breakdown
`createdAt`	`Date`	Always	Creation timestamp
`expiresAt`	`Date`	Always	Expiry timestamp
`paidAt`	`Date`	Paid only	Settlement timestamp
`paidTxHash`	`string`	Paid only	Transaction hash (Base58 for Solana, hex for Base)
`paymentChain`	`string`	Paid only	`"solana"` or `"base"`

Payment fields (paidAt, paidTxHash, paymentChain) are only present on paid invoices. They are undefined for open, expired, and canceled invoices.
