Flows
End-to-end use cases for Bre-B Participant — payin and payout.
A flow is a complete, end-to-end use case that composes several Bre-B concepts together. While the Concepts section answers "what is a payment key, target, or tenant account?", flows answer "how do I receive a Bre-B payment, or send one?".
Flows are grouped by commercial capability:
- Payin — receiving a Bre-B payment from another participant.
- Payout — sending a Bre-B transfer to another participant.
