# Qr Code

GET https://api.taktoria.com/api/v1/golinks/{linkId}/qr

The link's `shortUrl` as a QR code, black on white: an SVG, or a PNG
with `format=png`. It holds the short link, never the destination,
so re-pointing the link does not break a code already printed, and
every scan is counted. Put a workspace's own Go Links hostname on a
poster: this installation's `/go/` asks whoever scans it to sign in.
`Content-Type` is `image/svg+xml` or `image/png`.

Reference: https://docs.taktoria.com/api-reference/golinks/qr-code

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Servers

- `https://api.taktoria.com/api/v1` (Production, default)
- `http://localhost:3000/api/v1` (Local)

## Request

### Path parameters

- `linkId` (string, required)

### Query parameters

- `format` (enum, optional) — `svg` unless asked.
  - Allowed values: `svg`, `png`
- `size` (integer, optional) — Width in pixels, 160 to 1024. Defaults to 512.
- `download` (boolean, optional) — Present, the answer carries `Content-Disposition: attachment` with a filename such as `go-team-roadmap.svg`.

## Response

### 200

- File download.

## Errors

### 404 Not Found Error

- `error` (ErrorDetail, required)

### 402 Subscription Required Error

The organization has no subscription for the app that lets it in: active, trialing or past due. One that is unpaid (Stripe stopped retrying a failed payment), paused, incomplete or cancelled answers this too, and the message says which: an unpaid app is locked until a workspace admin updates the payment details. `details.status` is the app's subscription status (null with none), and `details.paymentIssue` is `unpaid`, or `payment_failed` for an incomplete one whose first payment failed, as `paymentIssue` on `GET /subscription` reckons it; null when a payment is not why.

- `error` (ErrorDetail, required)

### 429 Too Many Requests Error

Rate limited (`rate_limited`): the key, the signed-in person, the workspace or an expensive endpoint's own budget is used up for now. `Retry-After` says how many seconds to wait, and `details` names the `policy`, its `limit`, `windowSeconds` and `retryAfter`. Every answer to an authenticated request carries the IETF `RateLimit-Policy` and `RateLimit` headers, so a client can slow down before it gets this. Nothing was done; wait and send it again. See "Rate limits".

- `error` (ErrorDetail, required)

## Types

### ErrorDetail

- `code` (string, required) — A stable machine-readable code such as `not_found`.
- `message` (string, required)
- `details` (any, optional)
