# Decision Record: Payment Boundary
|
|
|
|
## Context
|
|
We need to define clear boundaries around the payment processing functionality in our system to ensure maintainability, separation of concerns, and adherence to clean architecture principles. The system will interface with external payment gateways, which introduces potential risks and complexities.
|
|
|
|
## Decision
|
|
We have decided to isolate the payment gateway integration behind a port interface, allowing the domain logic to remain agnostic of the actual payment gateway being used. This means that the domain layer will define interfaces (ports) for payment interactions, while the implementation (adapters) will handle specific payment methods (e.g., credit card, PayPal, etc.).
|
|
|
|
## Alternatives
|
|
1. **Direct Integration**: Integrate the payment gateway directly within the domain layer.
|
|
- **Consequences**: This would tightly couple the domain logic with specific payment gateways, making the system harder to maintain and adapt to changes in payment providers.
|
|
|
|
2. **Use of Service Layer**: Introduce a service layer that manages payment operations.
|
|
- **Consequences**: While this adds a layer of abstraction, it does not solve the core issue of the domain being aware of payment details. This approach may complicate the architecture without clear benefits.
|
|
|
|
## Consequences
|
|
- By isolating the payment gateway integrations through a port interface, we ensure that business logic remains clean and focused on core functionalities, enabling easier testing, adaptation, and maintenance in the future.
|
|
- This architecture choice facilitates ease of switching payment providers with minimal impact on the core domain logic. |
