Newbie Question: Connect Ghost to Different Payment Service Using Zapier?

A company I’m advising is thinking of using Ghost to publish a newsletter. It would be a free newsletter but paying subscribers would get members-only articles and access to a discussion board. This company uses a the givingfuel.com payment provider rather than Stripe.

GivingFuel supports Zapier.

I’m a Zapier newbie as well as a Ghost newbie.

Can I substitute GivingFuel in place of Stripe on Ghost, using Zapier?
