ISO WebSim

A very short screencast - https://youtu.be/vSRZ_nzU-Jg

Pulling a docker image would be the quickest way to run without any hassles of building/configuring etc!

Iso Websim is a ISO8583 simulator built using Go, React, Material-UI and other amazing open source libraries.

    • ASCII, EBCDIC, BCD and BINARY encoding for fields
    • Fixed, Variable, Bitmapped fields
    • Embedded/Nested fields
    • Supported MLI's - 2I, 2E, 4I, 4E
  • Define and run servers based on specs
    • Run servers from the UI or in standalone mode
    • Rules to respond to messages based on fields (rules based on amount, currency etc)
  • A UI to build and send transactions to servers (as a client)
    • Ability to edit fields on UI
    • UI hints to render special fields
    • Client-side validation of fields for content, length
    • PIN and MAC generation
    • Padding support
    • Save messages that be can be replayed later
    • Build Test Cases that can be saved and re-run for regression testing etc
