Upload a receipt, bill or sales invoice to the Costs or Sales inbox.

Dext API: https://cotlet.dev/docs/api/dext.md

`POST https://cotlet.dev/api/v1/dext/documents`

Access: write.

Uploads one file through Add documents and returns the new item in Processing. Images and PDFs may be up to 6MB, ZIP files 100MB. Mode one_per_file takes PDF, JPG, PNG or ZIP; one_per_page and auto_split take PDF only. The upload reaches no one and the item can be archived, so it runs without asking.

| `inbox` | enum | no | costs or sales. Default: costs. |
| `file_url` | string | yes | HTTPS link to the file Cotlet downloads. |

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.
