Can I set the QR code entirely from a custom field?

Can I set the QR code entirely from a custom field?

Yes. To make the QR code dynamic based on a custom field, set the QR code value in the message template to:

~CUSTOM1~

Then, for each recipient, make sure the corresponding custom field contains a valid URL. The QR code will automatically generate using that URL.

Note: Currently, only ~CUSTOM1~ is supported for QR code generation.
