Data Flow

1. Frontend: User creates workflow with payment module
   ↓
2. ExecModuleConfigBuilder: Renders form based on module definition
   ↓
3. Frontend: Validates form & submits payload
   ↓
4. Backend: ValkyrWorkflowService receives workflow
   ↓
5. WorkflowExecutor: Orchestrates task execution
   ↓
6. ExecModule: CryptoBuySellModule or MasterCardAgentPayModule receives input
   ↓
7. Module: Validates risk controls, formats platform-specific request
   ↓
8. Module: Calls external API (Coinbase, Kraken, Binance, or MasterCard)
   ↓
9. Module: Receives response, emits EventLog, persists to WorkflowState
   ↓
10. Frontend: Receives real-time updates via WebSocket
    ↓
11. Frontend: Displays execution status, transaction details, EventLog

🔧 Key Implementation Details

VModule Pattern

All payment modules extend VModule and implement:

@Override
public Flux<EventLog> executeReactive(Workflow workflow, Task task, ExecModule module) {
  return Flux.create(sink -> {
    try {
      // Emit progress events
      sink.next(createEvent(EventLog.StatusEnum.OK, "Starting..."));

      // Do work...

      // Persist results to WorkflowState
      putState(workflow, "crypto.order.result", resultJson);

      // Emit success
      sink.next(createEvent(EventLog.StatusEnum.OK, "Complete"));
      sink.complete();
    } catch (Exception e) {
      // Emit error
      sink.next(createEvent(EventLog.StatusEnum.ERROR, e.getMessage()));
      sink.complete();
    }
  });
}

Integration Account Management

// Retrieve encrypted credentials
IntegrationAccount account = integrationAccountService.findById(accountId);
String apiKey = account.getApiKey();           // Decrypted transparently
String secret = account.getPassword();          // Decrypted transparently
String environment = account.getAccountType();  // "sandbox" or "production"

Risk Controls

// Built-in velocity checks prevent fraud
if (validationResult.getDailyVolume() + amount > maxDailyVolume) {
  throw new RiskControlViolation("Daily volume limit exceeded");
}
if (amount > maxSingleOrder) {
  throw new RiskControlViolation("Single order limit exceeded");
}

Error Handling

// Errors are captured as EventLog entries, not exceptions
Map<String, Object> errorResult = Map.of(
  "status", "error",
  "code", "EXCHANGE_API_ERROR",
  "message", e.getMessage(),
  "timestamp", Instant.now()
);
putState(workflow, "crypto.order.error", OM.writeValueAsString(errorResult));
