Create a sales invoice as a draft, or approve it right away.

Holded API: https://cotlet.dev/docs/api/holded.md

`POST https://cotlet.dev/api/v1/holded/contacts/{contact_id}/invoices`

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

Creates one sales invoice for a contact. With approve false, the default, it is saved as a draft you can still edit. With approve true it is approved, and an approved Holded invoice cannot be edited or deleted, only voided. The number comes from your Invoicing preferences, and the date defaults to today. Due date is one date. Taxes use the tax names in your account. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `contact_id` | string | yes | Contact ID from list_contacts. |
| `items` | array | yes | Lines of the document. Each line has name, description, units, price and tax (the tax as named in Holded). Optional discount in percent per line. Use a product from list_products or a new name. |
| `date` | date | no | Invoice date. Default: today. |
| `due_date` | date | no | Due date. |
| `message` | string | no | Text shown at the bottom of the invoice. |
| `approve` | boolean | no | true approves the invoice, false saves a draft. Default: false. |

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.
