Or mo' money, mo' problems.. Integrating recurring payments in your SAAS app. A talk to the Ruby Ireland user group at the Twisted Pepper, in Dublin.
I gave an overview on the basics of taking payments online, specifically;
* Payment Gateways
* Libraries/code/web services available for your Rails app.
I explained each core method implemented in an ActiveMerchant billing gateway class, and I covered the important design decisions I took before building in recurring billing;
* High level decisions (which bank/gateway etc.)
* Pricing decisions (price plans, upgrade/downgrade paths/logic etc.)
* Actual implementation decisions (how its coded etc.)
Finally I talked about some pain points you’ll likely to come across when working with recurring billing and online payments in general. I hope everyone enjoyed the talk and I’d be happy to answer any further questions if you have them.
