Never mind, already got it!
I have an additional question. The above works, but I want to use that with a submission ID instead of a form ID, is that possible?
Okay thanks. Can I use the same to edit a submission, instead of editing it in the backend? We want someone to check and maybe edit the submission before we change the state to ‘Paid’.
I know of that possibility, but it is a lot of work to do this if you have a lot of fields and forms.
