There’s an interesting blog post over at RoRe comparing Stripe vs ActiveMerchant Given this is an area of interest for many of our US customers (Stripe is currently only available in the US) I thought I’d highlight it here. As it relates to Spreedly Core customers who are using Stripe the situation is slightly different. That’s because Spreedly Core is handling the credit card storage and processing these types of requests . Here’s the documentation if you want to dig deeper. Feel free to ask any questions here or add to the discussion over at RoR.
