## updateInvoice

Use when updating invoice metadata or due date (e.g. PDF URL, net terms), or when recalculating this draft invoice's discount from its current standing coupon associations via apply_discount:true (idempotent, does not attach a new coupon). Allowed for invoices in draft or finalized status.

### Example Usage

<!-- UsageSnippet language="typescript" operationID="updateInvoice" method="put" path="/invoices/{id}" -->
```typescript
import { Flexprice } from "@flexprice/sdk";

const flexprice = new Flexprice({
  apiKeyAuth: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const result = await flexprice.invoices.updateInvoice("<id>", {});

  console.log(result);
}

run();
```

### Standalone function

The standalone function version of this method:

```typescript
import { FlexpriceCore } from "@flexprice/sdk/core.js";
import { invoicesUpdateInvoice } from "@flexprice/sdk/funcs/invoices-update-invoice.js";

// Use `FlexpriceCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const flexprice = new FlexpriceCore({
  apiKeyAuth: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const res = await invoicesUpdateInvoice(flexprice, "<id>", {});
  if (res.ok) {
    const { value: result } = res;
    console.log(result);
  } else {
    console.log("invoicesUpdateInvoice failed:", res.error);
  }
}

run();
```

## getInvoicePdf

Use when delivering an invoice PDF to the customer (e.g. email attachment or download). Use url=true for a presigned URL instead of binary. Use force_generate=true to regenerate and re-upload the PDF even if one already exists in S3.

### Example Usage

<!-- UsageSnippet language="typescript" operationID="getInvoicePdf" method="get" path="/invoices/{id}/pdf" -->
```typescript
import { Flexprice } from "@flexprice/sdk";

const flexprice = new Flexprice({
  apiKeyAuth: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const result = await flexprice.invoices.getInvoicePdf("<id>");

  console.log(result);
}

run();
```

### Standalone function

The standalone function version of this method:

```typescript
import { FlexpriceCore } from "@flexprice/sdk/core.js";
import { invoicesGetInvoicePdf } from "@flexprice/sdk/funcs/invoices-get-invoice-pdf.js";

// Use `FlexpriceCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const flexprice = new FlexpriceCore({
  apiKeyAuth: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const res = await invoicesGetInvoicePdf(flexprice, "<id>");
  if (res.ok) {
    const { value: result } = res;
    console.log(result);
  } else {
    console.log("invoicesGetInvoicePdf failed:", res.error);
  }
}

run();
```

## recalculateInvoice

Starts an async workflow that creates a fresh replacement invoice for a voided SUBSCRIPTION invoice (same billing period). Returns workflow_id and run_id; poll workflow status or GET the new invoice via recalculated_invoice_id after completion.

### Example Usage

<!-- UsageSnippet language="typescript" operationID="recalculateInvoice" method="post" path="/invoices/{id}/recalculate" -->
```typescript
import { Flexprice } from "@flexprice/sdk";

const flexprice = new Flexprice({
  apiKeyAuth: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const result = await flexprice.invoices.recalculateInvoice("<id>");

  console.log(result);
}

run();
```

### Standalone function

```typescript
import { FlexpriceCore } from "@flexprice/sdk/core.js";
import { invoicesRecalculateInvoice } from "@flexprice/sdk/funcs/invoices-recalculate-invoice.js";

// Use `FlexpriceCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const flexprice = new FlexpriceCore({
  apiKeyAuth: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const res = await invoicesRecalculateInvoice(flexprice, "<id>");
  if (res.ok) {

## voidInvoice

Use when cancelling an invoice (e.g. order cancelled or duplicate). Only unpaid invoices can be voided.

### Example Usage

<!-- UsageSnippet language="typescript" operationID="voidInvoice" method="post" path="/invoices/{id}/void" -->
```typescript
import { Flexprice } from "@flexprice/sdk";

const flexprice = new Flexprice({
  apiKeyAuth: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const result = await flexprice.invoices.voidInvoice("<id>");

  console.log(result);
}

run();
```

### Standalone function

The standalone function version of this method:

```typescript
import { FlexpriceCore } from "@flexprice/sdk/core.js";
import { invoicesVoidInvoice } from "@flexprice/sdk/funcs/invoices-void-invoice.js";

// Use `FlexpriceCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const flexprice = new FlexpriceCore({
  apiKeyAuth: "<YOUR_API_KEY_HERE>",
});

async function run() {
  const res = await invoicesVoidInvoice(flexprice, "<id>");
  if (res.ok) {
    const { value: result } = res;
    console.log(result);
  } else {
    console.log("invoicesVoidInvoice failed:", res.error);
  }
}

run();
```
