I don't think the average ISO has the knowledge let alone a published set of credentials to receive card data, the ISO industry really sticks to the tooling platforms provide.
Conversely, if you’re anything but the most plain jane business, I would avoid transitioning from Stripe to Gravity like the plague. I watched them reject a candy company and a knitting goods business that were both reputable, over a decade in business each, and never had an abnormal spike in sales or questionable products on offer. Gravity either couldn’t get Stripe data transferred or properly integrated and ended up turning away both businesses (while blaming them for noncompliance).
