Negative Flows

Jump to Section

For all the flows, except the transfer creation, the wrapper processes will capture and return the process errors regardless of their type. The UI application creates the adapted logic based on the captured errors.

For the transfer flows, the Mambu Process Orchestrator (MPO) processes respond with the process errors which occur until the creation of the Wise transfer. This step triggers a response to the wrapper process stating that the transfer has been initiated and providing the Wise transferId.
