Rural branches and loan officers at group meetings often lose signal mid-request. Zung's Banking API accepts a client_ref on repayments, deposits and withdrawals: a retry with the same reference returns duplicate: true and posts nothing.
How it works
- 1Generate a UUID per transaction on the device
- 2Queue transactions while offline
- 3Post each one with its client_ref when back online
- 4Treat success and duplicate responses as done
