Source: https://cotlet.dev/docs/api/procountor/approve_sales_invoice

Approve an Unfinished sales invoice so it can be sent.

Procountor API: https://cotlet.dev/docs/api/procountor.md

`POST https://cotlet.dev/api/v1/procountor/invoices/{invoice_id}/sales-invoice/approve`

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

Does what Approve does in Invoice view. The status changes from Unfinished to Not sent, and Procountor counts the invoice in Accounting Act and tax reports. Only approved invoices can be sent. By default you confirm each call; you can switch that off for this tool.

## Parameters

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.
