Docs sections: [Get started](https://cotlet.dev/docs.md) · [REST API](https://cotlet.dev/docs/api.md) · [MCP](https://cotlet.dev/docs/mcp.md) · [SDKs & CLI](https://cotlet.dev/docs/sdks.md) · [Integrations](https://cotlet.dev/docs/integrations.md)

Adds a receipt image or file to an expense, or replaces the one on it.

Expensify API: https://cotlet.dev/docs/api/expensify.md

`POST https://cotlet.dev/api/v1/expensify/expenses/{expense_id}/receipt/attach`

Access: write.

Attaches the file at the URL to the expense and returns the receipt link. Expensify posts an "added a receipt" message on the expense showing who made the change. It reaches no one and you can replace the file in Expensify, so it does not wait for your OK. On an Approved report only a Workspace Admin can attach or replace a receipt; otherwise the call returns the role problem.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `expense_id` | string | yes | Expense ID from list_expenses. |
| `receipt_url` | string | yes | HTTPS URL of the receipt image or file. |
| `replace` | boolean | no | Replace an existing receipt. Default: false, which fails if one is attached. |

```bash

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.
