How to read the diagrams
- Origin. The flows are a suggested reading of the official manuals that BACEN and the market infrastructures publish. A manual defines each message and its fields. A manual does not define the order between messages, so the order shown here is an interpretation.
- Responsibility. The participant in the payment arrangement is your institution. Your institution validates each flow against the manuals in force and implements it on top of the Lerian APIs.
- Scope. A diagram shows the usual path of a journey. Exceptions, cut-off times, and rules for each product follow the manual of each infrastructure.
