Mapping QR code value

Important notes​

  • QR codes encode text — the format of the value determines behavior
  • Common use case: encode a URL

Example:

https://example.com/product/123

Result​

When the workflow runs:

  • the value is passed to Eledo
  • Eledo encodes it into a QR code
  • the QR code is rendered in the document
