In invoice template editing I only see options for layout, not for calculation. Is there a way to import data from an outside source via SOAP, something like:
field content set as https://myonlinecrcalculator.com/?in=1002, and this website returns <RF351002> (I would setup domain this myself of course)
Must I go self-hosted and hack it into the code myself?
Maybe I should setup a custom gateway for this, but I would like it to be visible on the PDF.
Or maybe I’m lucky and this is already built-in and I haven’t found it yet? Or maybe in the pipeline of the next big update? After all this is a common payment standard.
