QR Code

A QR code of a value made from text and fields.

Property	Required	Description
value	Yes	1 to 100 text and field nodes, without formatting
color	No	The code’s color. Black when left out
background	No	The color behind the code. Transparent when left out or null

The code is square, as large as fits in its box, and centered in it.

A value is a list of text and field nodes, joined together:

• { "type": "text", "text": "..." }, up to 4,000 characters
• { "type": "field", "attrs": { "expression": "order.id" } }

A submission fails with “A QR code has no value.” when the value comes out empty, and with “The QR code can’t hold this value” when it’s too long for a QR code.

Example

    { "type": "field", "attrs": { "expression": "order.id" } }
  ],
