Active Merchant is a Ruby payment abstraction library extracted from Shopify that provides a unified API across dozens of payment gateways. It integrates seamlessly with Ruby on Rails but also works as a standalone Ruby library for processing credit card transactions.
Use cases
- process credit card payments in a Ruby app
- unify multiple payment gateways behind one API
- add billing to a Rails application
- charge customers via different payment processors
- validate credit card details before charging
- authorize and capture payments programmatically
When to choose
- you're building a Ruby or Rails application that handles financial transactions
- you need to support multiple payment gateways with a consistent interface
- you want a battle-tested library in production use since 2006
- you need credit card validation and payment abstraction without vendor lock-in
When to avoid
- your project is not in Ruby
- you need a full e-commerce platform rather than a payment library
- you only use a single gateway and prefer its native SDK
- you need non-card payment methods like wallets or bank transfers not covered by supported gateways
