Email the customer a portal link to an invoice.

Method CRM API: https://cotlet.dev/docs/api/method-crm.md

`POST https://cotlet.dev/api/v1/method-crm/invoices/{invoice_id}`

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

Does what Send > Email does: the customer gets a link to their portal, where they can view the invoice and pay if a payment gateway is set up. It fails if the contact has no email. 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. |
| `subject` | string | no | Email subject. Default from your template. |
| `body` | string | no | Email text. Default from your template. |
