Will your billing code survive launch day?

Build a rock solid Stripe integration from day one.

Writing a Stripe integration is intimidating

There are lots of moving pieces and no one place to see a complete implementation. You've probably asked yourself a million questions:

Am I making charges correctly?

What happens to errors?

Am I dealing with webhooks properly?

What are the right gems to use?

Am I PCI compliant? What is PCI, anyway?

Simple tutorials only go so far. Blog posts from years ago are easy to find, but are they still correct? API documentation doesn't help if you don't know what you're looking for.

Mastering Modern Payments: Using Stripe with Rails distills the experience of building dozens of Stripe integrations into one concise, comprehensive guide.

From first chapter to last, MMP is packed with advice and examples:

Basic Integration guides you through the most basic Stripe billing system possible and prepares your app for the rest of the book.

Security and PCI Compliance guides you through the murky waters of the Payment Card Industry Data Security Standards and how they apply to Stripe. It also talks about security scanners and code analysis tools you can use to validate your code isn't susceptible to things like cross-site-scripting attacks and SQL injections.

Custom Payment Forms shows you how to get away from Stripe Checkout and build your own payment forms, your way, with your own framework.

State and History teaches you why and how you should build your application with explicit state machines. It also walks through why keeping audit logs of the changes to your models is so very important, and how you can get them with just one line of code.

Handling Webhooks describes how to handle Stripe's webhook events to alert you of errors, perform vital upkeep within your application, and send receipts to customers.

Background Workers describes how to communicate with Stripe asynchronously. The Internet is a wild, wacky place, and your application needs to be able to recover from any number of errors, both internal and external.

Subscriptions walks through your options for building recurring billing into your application, along with advice about emailing your customers and integrating analytics services.

Connect and Marketplaces adds onto the basic integration again, this time allowing your app to sell things on your users' behalf with Stripe Connect and send them payments with Transfers.

MMP has helped 1,303 people confidently earn more than $2 million dollars by getting their Stripe integration set up in hours, not days.

Mastering Modern Payments was like a pool of cool refreshing water after I'd been traveling in the desert of obscurity for weeks. Unlike the API docs, or most blog posts I found on the topic, Pete thought this through three steps ahead of solving the problems I'd be having a few weeks or months after deployment. This will end up saving me an immeasurable amount of time and money.

I'm fairly new to Rails and setting up billing had me flustered for weeks. I was stuck, spinning my wheels, not knowing what was the best route to take. Pete's book is a guiding light of common sense and practical application. Now I can setup billing with confidence, and more importantly, ship my product.

Mastering Modern Payments is a fantastic resource for integrating Stripe billing with your Rails app. Pete does a great job of pulling together existing resources and blending them with his own experience to provide a clear, valuable guide for billing with Stripe.

I completely re-wrote my checkout using MMP's ideas. It's all looking much neater and more bullet proof now. The book gave me a lot of confidence my app wasn’t cowboy coded.

A Letter from a Happy Customer

Though I was somewhat familiar with Stripe, and wrote a not-insubstantial online store that has processed hundreds of thousands of dollars in charges in the last couple of years, I was never happy with the code I wrote. It felt fragile, and I had no real clue how to do things I wanted to, like moving it into a worker.

I bought the book yesterday, and chewed through it pretty quickly, and it gave me the confidence to do some serious refactoring of my code. Today, I’ve made sweeping changes based on your work, including moving things to a state machine and using a worker to take care of the stripe calls. This is a significant win for me, and I did it in a fraction of the time that it would’ve taken me otherwise. So: thanks. Your book paid for itself about five times over already.

Anyway, thanks again. You made my week much more satisfying than I’d expected it to be. :D
