I tried Bright hooks the other day for this exact scenario, and while it seems I set up the webhook correctly, I can't see the QR code URL in the Marketo custom field I created and, in turn, the QR code image in the email.
Specifically, I can see the "Call webhook" activity in the activity log but I can't see the "Change data value".
I think I followed all the steps pretty strictly, I have no idea what I might have overlooked.
I need to do exactly what you rare suggesting here. Put the last value in a list of license keys into a data field. However I cant seem to find anything to explain the process.
Are you aware of any info that runs through the set up.
Thanks in advance

If in case you have a list of valid gift codes and need to pick a 'next unused promotion code' for each request, you can use a web hook from
