How do I get Magic Tag values in an action?

Hi,

I’ve got a client who’s asked me to create an API link for Caldera. So far, using caldera_forms_submit_complete, I can get all the visible field data and submit that, but the scope has now changed to require Stripe data too.

As far as I can see, the Stripe transaction ID and amount are stored in ‘Magic Tags’, but I can’t see any way to load that data in the PHP.

Is there an easy function to read a magic tag? Am I looking in the wrong place?
