EFN QR Redirect Service

Generate direct QR codes, or mint a new qr.efn.no redirect and encode that instead.

Use the authenticated https://qr.efn.no/api/v1/qr endpoint in two main ways. Direct mode encodes the supplied target_url immediately. Short-link mode uses POST with mode=short to create a new internal https://qr.efn.no/r/<slug> redirect, then returns a QR code for that internal URL. If you want a branded center logo, upload it as logo_file=@... as part of the same request.

Mode 1: direct target_url QR Mode 2: generated short redirect QR HTTP Basic auth or browser session required No built-in logo library Upload SVG, PNG, JPEG, or GIF Max upload size: 1 MiB

Short-link behavior

When you create a new internal redirect, the response includes X-Generated-Slug and X-Generated-Redirect-URL headers so you can reuse the generated short URL outside the QR image itself.

Access model

Public redirects stay open. Creating QR images or new short links through the API requires either an authenticated browser session or HTTP Basic auth, without changing the direct-versus-short-link API shape.

Copy-Paste cURL Commands

Mode 1: direct QR

Generate a PNG QR that encodes the target URL directly with no internal redirect hop.

curl -u "$QR_USER:$QR_PASSWORD" -L 'https://qr.efn.no/api/v1/qr?target_url=https%3A%2F%2Fwww.vg.no&format=png' \
  -o vg-direct-qr.png

Mode 2: create short redirect QR

Create a new qr.efn.no redirect with redirect_type 307, return the QR image, and inspect the generated slug in the response headers.

curl -u "$QR_USER:$QR_PASSWORD" -L -D short-link.headers \
  -F 'target_url=https://www.vg.no' \
  -F 'mode=short' \
  -F 'redirect_type=307' \
  -F 'format=svg' \
  https://qr.efn.no/api/v1/qr \
  -o vg-short-qr.svg

Direct QR with uploaded SVG logo

Send a multipart POST with your own SVG logo file and get back an SVG QR in direct mode.

curl -u "$QR_USER:$QR_PASSWORD" -L \
  -F 'target_url=https://www.medlemskap.efn.no' \
  -F 'format=svg' \
  -F 'logo_file=@/path/to/logo.svg;type=image/svg+xml' \
  https://qr.efn.no/api/v1/qr \
  -o custom-logo-qr.svg

Short redirect QR with uploaded bitmap logo

Create a new internal redirect and upload PNG, JPEG, or GIF artwork in the same request.

curl -u "$QR_USER:$QR_PASSWORD" -L -D short-link.headers \
  -F 'target_url=https://www.medlemskap.efn.no' \
  -F 'mode=short' \
  -F 'redirect_type=302' \
  -F 'format=png' \
  -F 'logo_file=@/path/to/logo.png;type=image/png' \
  https://qr.efn.no/api/v1/qr \
  -o membership-short-branded.png

Tip: use plain GET requests with credentials when you only need a QR image for the destination itself. Use POST mode=short when you want a newly created reusable qr.efn.no link that can be shared outside the QR image too.
