# GET /api/v2/invoices/{invoice}

Read an invoice

- MCP id: invoices.show
- Scope: api:read:invoices
- Permission: invoices::read
- Needs the billing feature on your organisation
- Rate cost: 1 unit, read bucket.
- Cache-Control: private, no-store

Returns one invoice in the detail view.

Invoices are hard-deleted and are removed with their project, so a deleted invoice is gone and answers `404`. The path takes the numeric id only: this resource has no alternate key, unlike a sales invoice, which can also be addressed by `invoice_number`.

## Parameters
- invoice (integer, path): The Invoice's numeric id.
- view (string, optional): Which field set to render.
- X-Request-Id (header, optional): A correlation id of your own. It is recorded in our logs next to the server's request id but never returned: the response header always carries the server's id. A value that does not match the pattern is discarded silently, never rejected.
- If-None-Match (header, optional): The ETag a read is conditional on. A match is answered 304 with no body.

## Response 200
- id (integer, required): Unique identifier.
- project_id (integer, required): Project this invoice was raised for.
- project (Ref or ProjectSummary, required): The project this invoice was raised for.
- user_id (integer or null, required, server-assigned): Employee the invoice is attributed to. Assigned from the authenticated user on create and never writable; `null` once that user is deleted.
- user (Ref or UserSummary or null, required): The employee this invoice is attributed to. Expanding it with `?include=user` additionally requires the `users::read` permission and a token scope covering the users prefix.
- description (string, required, multiline): What was invoiced, as free text. This is the field `?q=` searches.
- date (date (YYYY-MM-DD), required): Invoice date, a zone-free calendar date. Newest first is the default sort.
- hourly_rate (decimal (2 dp) ≥ 0, required): Hourly rate this invoice was billed at, as a decimal string with two places. Never rounded or rescaled.
- created_at (timestamp (YYYY-MM-DDThh:mm:ssZ), required): Creation timestamp.
- updated_at (timestamp (YYYY-MM-DDThh:mm:ssZ), required): Last-write timestamp; use for incremental sync. It also feeds the `ETag` revision, because a legacy invoice has no `version` field.
- links (InvoiceLinks, required)
  - self (url, required): The canonical URI of this record.
