This example shows how to create a rule, show parameters, and execute it.
Rules Modeling for Examples
Step 1
Register an adapter of Standard Rule type.
Step 2
Model a “VATcalculation” rule with the suggested values.
Descriptive Name |
VATcalculation |

Standard Rule |
JAVA code |
VATvalue = (VATrate * Entryamount) / 100 ; Totalamount = Inputamount + VATvalue ; |
Input Parameters |

In the properties panel, on the "General" tab, select the Deploy Rest API property. This option allows the rule to be consumed as Rest API externally.
Step 3
In the "Permissions" option, add the security function "Execute rule via Rest + RuleName" to a new permission, for example "ApiRestPermission".
Step 4
Assign to the previously created user the generated permission.
