Gringotts

Gringotts is an Elixir library designed to streamline the integration of various payment gateways into Elixir applications. It provides a standardized API that abstracts the unique complexities and interfaces of different payment providers, allowing developers to interact with multiple gateways using a single, consistent set of functions. This significantly reduces the development effort and maintenance overhead associated with managing diverse payment integrations.

The library offers core functionalities such as authorizing payments, capturing previously authorized funds, processing direct purchases, issuing refunds, and voiding transactions. Additionally, it includes features for securely storing and unstoring credit card information, which is crucial for recurring payments or customer account management. Gringotts emphasizes a modular design, enabling developers to easily extend its capabilities by creating custom adapters for new payment gateways, ensuring future-proofing and flexibility for evolving business needs. It also provides structured response objects to clearly indicate the success or failure of a transaction, simplifying error handling and status management within the application.
