Turn a draft into a published invoice with an invoice number.

Bokio API: https://cotlet.dev/docs/api/bokio.md

`POST https://cotlet.dev/api/v1/bokio/invoices/{invoice_id}/publish`

Access: write. Confirm: waits for the user's OK before it runs.

Publishes a draft invoice, which assigns the invoice number and the payment reference and makes it final for the customer. Publishing does not email the invoice; use send_invoice for that. A published invoice is no longer edited like a draft. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `invoice_id` | string | yes | Invoice ID from list_invoices or create_invoice. |

## Request

**cURL**

```bash
curl -X POST https://cotlet.dev/api/v1/bokio/invoices/invoice_8c41d2/publish \
  -H "Authorization: Bearer $COTLET_API_KEY"
```

**Python**

```python
result = client.call("bokio", "publish_invoice", {"invoice_id":"invoice_8c41d2"})
```

**Node.js**

```js
const result = await cotlet.call('bokio', 'publish_invoice', {"invoice_id":"invoice_8c41d2"});
```

**CLI**

```bash
cotlet call bokio publish_invoice --data '{"invoice_id":"invoice_8c41d2"}'
```

## Example response

```json
{
  "invoice_id": "f2d84b1a-6c30-4e97-8a5b-1d9c7e3a40b2",
  "status": "published",
  "invoice_number": "2026-1042",

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
