Active Merchant
Active Merchant is a Ruby library that provides a payment gateway abstraction layer to process credit card transactions across multiple different payment processor APIs. It serves as a payment API wrapper, offering a consistent set of commands and classes that abstract the complexity of various provider request and response formats.
The library utilizes a unified payment gateway API to standardize global payment processing and unify payment flows. It specifically includes a standardized interface for handling 3D Secure authentication and identity verification for card-not-present transactions.
The project covers core capabilities for credit card transaction processing, including the authorization and capture of funds. It achieves this by translating generic payment calls into provider-specific formats and mapping raw API responses into standardized internal objects with consistent success and failure attributes.
