Orchestration Data Flow Use Cases

These are high-level data flow that encompass typical interactions in the orchestration. This info is intended as an artifact for the ICS - Architectural Secure Design Review.

Use Cases

Use Case 1: Payment via Digital Interface(DI)

1. User sends a payment via the DI app.
2. The jX gateway sends a PmtHubCrXferAdd request to the WOS2 orchestration endpoint.
3. Orchestration looks up customer via BlueServices API.
4. Orchestration submits token validation request to Zelle Shared Directory API.
5. Orchestration submits fraud check request to Yellow Hammer API.
6. Orchestration performs TrnAdd via jX to debit the sender.
7. Orchestration creates the payment via the Zelle Shared Directory API.
8. Orchestration updates the BlueServices API.
9. Orchestration sends an ENS message via the BlueServices API.
10. Orchestration responds to the DI.

Use Case 2: Consume EWS Queue Message

1. EWS sends a network message via IBM MQ.
2. Orchestration consumes message from IBM MQ.
3. Orchestration looks up Zelle entities via BlueServices API.
4. Orchestration performs TrnAdd via jX to debit the sender.
5. Orchestration updates Zelle entities via BlueServices API.
6. Orchestration sends an ENS message via the BlueServices API.
