IMPLEMENTATION BOUNDARY

Provider logic stays
outside commerce rules.

The goal is not to make Thonem depend on a provider. It is to give the provider a small, testable adapter that translates between its contract and the commerce domain.

01

Normalize

Map provider-specific requests and responses into internal commerce commands and events.

02

Verify

Authenticate callbacks and validate state transitions before applying business side effects.

03

Observe

Log references, latency and failure classes so provider outages can be diagnosed without obscuring transaction truth.

PROJECT CHECKLIST
  • Use the project’s current Paymob API contract and callback requirements as the source of truth.
  • Do not mark an order paid from a browser redirect alone; use verified server-side transaction evidence.
  • Deduplicate repeated callbacks before order or fulfillment side effects.
