Templates and Transactions Parameters

While creating a template, you may need to define template and transaction parameters based on your need. This document guides on how to use the different types of parameters. It also describes how do these parameters function with different settings. This page also discusses the characteristics of the various fields on the Add Template/Transaction Parameters screen and their effects on the parameters' representation.

On the following screen, when you click Add Parameter, it guides you to the page that lets you add the template or transaction parameters.

Below is the screen that asks you for the details described in the table that follows to add a parameter.

As you set the values for some of these fields, for example, Display Name, Tooltip, the corresponding changes reflect in several pages related to the template and transactions. You may also need to do some additional settings in case of some specific type of parameters, for example, Combo and Text. The following sections talk of these fields, their possible values and settings, and the changes they bring into effect.

  To call a REST Consumer to populate the values: 
  1. Select the Dynamic check box.

  • on/off
  • 1/0
  The default value for each of the selected options is Unchecked.

    {
        "value": "AllDays"
    },
    {
        "value": "BusinessDays"
