QR code formats

The QR code image will be returned as a URL in the response for one-time payment, merchant redirect and merchant callback QR codes. Opening this URL will return the image in the format and resolution set in the request. The URL to the image will look like this:

"url":"https://qr-generator-prod-app-service.azurewebsites.net/qr-generator/v1?token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...."

The URL to the image does not require any authentication and can be shown wherever you want. Note that one-time payment QR codes eventually will time out - trying to open the URL to the one-time payment QR image after its expiry while will return a 404 Not Found error. Merchant redirect QR codes can be opened forever.

QR Image format

The API currently supports generating QR codes in either PNG or SVG image formats. If PNG is chosen, it is also possible to set the resolution of the image.

Set the Accept HTTP Header to either Accept: image/png or Accept: image/svg+xml.

Setting QR image size

If a PNG image is selected, the size parameter can be used to set the resolution of the image. The example below sets the image to 600 x 600 pixels:

{
  "url": "https://api.vippsmobilepay.com/...",
  "size": 600
}

The smallest image you can set is 100 x 100 pixels and the largest is 2000 x 2000 pixels. If left out, the image is set to 1024 x 1024 pixels by default.

Adding white border

In order to add a white border to the QR code image, add the parameter whiteBorder with the width of the border in pixels.

{
  "url": "https://api.vippsmobilepay.com/...",
  "whiteBorder": 10
}

whiteBorder can be a minimum of 0 and a maximum of 100. If left out, whiteBorder is set to 8 by default.
