I am trying to incorporate Hint data in some cross platform reports that I am building that covers the totality of our clients experience. From the reports i have been able to export, i cannot find a filed that will join the hint invoice to the Stripe Charge record. I see some meta data being added to each stripe charge, {"via": "Hint Health", "hint_id": "pmt-xxxxxxxxxxx, "hint_type": "Payment"}, but cannot find the "pmt-xx..." id in Hint anywhere. Could you help me to understand how i can uniquely join the Hint data to the Stripe data?
