Environment variables (ISO)

Environment variables help store values you use again and again in ISO requests.

Example uses:

  • Server address (host, port)
  • Terminal ID
  • Message type (MTI)

By storing values in ENV, you can easily change them in one place.

Adding Environment Variables

Create POS_Env:

  1. Click Environments submenu → new
  2. Add variables:
    • ip: localhost
    • terminalId: 12345678
    • Atm_req_mti: 0200
    • Atm_res_mti: 0210
    • processing_code: 310000

Using Environment Variables

Use {{key_name}} in fields.

Example:

<field id="0" value="{{Atm_req_mti}}"/>

Select POS_Env → Send ISO request using {{ip}}, {{port}},{{Atm_req_mti}}, {{processing_code}}.
