Transact Services Overview

Transact Services and functions are contained in individual project folders and include 4 key files:

• service-def.json: the Groovy Service definition
• service-help.html: the Help Doc file for display in the Journey Manager (JM) Service Definitions Help tab
• Service.groovy: the Service groovy script source file
• ServiceTest.groovy: the Unit Test groovy script

A simple example project service structure is shown below.

project

• src
  • com
    • maguire
      • helloworld
        • service-def.json
        • service-help.html
        • HelloWorld.groovy
        • HelloWorldTest.groovy

The service-def.json file refers to other resources in the project.

Service Definition

The Groovy Service Definition is provided in a service-def.json file. A simple example is shown below.

service-def.json

{
    "name": "Hello World",
    "type": "Fluent Groovy Service",
    "version": 1,
    "tmMinVersion": "5.0.0",
    "legacyGroovy": false,
    "parameters": [
        {
            "name": "groovyScript",
            "filePath": "HelloWorld.groovy"
        },
        {
            "name": "Unit Test Script",
            "filePath": "HelloWorldTest.groovy",
            "unitTest": true
        }
    ]
}

The service definition file specifies the bare minimum configuration necessary to create a valid service archive. Any missing configuration attributes and parameters are provided by the svcpackage task when you create a service archive. The service definition's type attribute is used to resolve the missing attributes and parameters from the standard service and function templates.

In your service definition file you can override default service template attributes and parameters.

A larger example is shown in the Fluent Dynamic Data service example below. This example includes a clientCode attribute for the Organization that owns the service.

The serviceConnection attribute is used to resolve a JM Service Connection entity at runtime. Service Connections are used to store common remote connection details used by multiple services. If the named service connection does not exist on the JM server a new one will be created with the given name and of type "HTTP Endpoint".

{
    "name": "TrackMe DD",
    "description": "Identity Verification Dynamic Data Service",
    "type": "Fluent Dynamic Data",
    "version": 1,
    "tmMinVersion": "5.0.0",
    "legacyGroovy": false,
    "serviceConnection": "TrackMe Connection",
    "clientCode": "Maguire",
    "parameters": [
        {
            "name": "TrackMe Account Key",
            "description": "TrackMe Account Key",
            "value": "ABC-123",
            "type": "String",
            "bind": false
        },
        {
            "name": "groovyScript",
            "filePath": "TrackMeDD.groovy",
            "fileIncludes": [
                "../common/trackme-utils.groovy",
                "../common/data-utils.groovy"
            ],
            "readOnly": true
        },
        {
            "name": "Unit Test Script",
            "filePath": "TrackMeDDTest.groovy",
            "readOnly": true,
            "unitTest": true
        }
    ]
}

Service Attributes

You can add arbitrary service attributes to your service definition. Attributes are optional unless otherwise indicated.

Attribute	Description
name	String Required. Service definition name.
description	String Service definition description.
type	String Required. Service type.
version	Number Required. Service version number.
tmMinVersion	String (Maximum length 20 characters) The minimum JM version required for the service. Formatted as a valid version string - see Version Attributes.
legacyGroovy	Boolean Whether the service uses legacy mode unsecure Groovy API.
serviceConnection	String The name of the service connection.
clientCode	String The client code, note this should generally be specified in svcupload Task.
parameters[]	Object See Service Parameters below.

Service Parameters

You can add arbitrary service parameters to your service definition. When you do so you need to specify the parameter attributes. Attributes are optional unless otherwise indicated.

Attribute	Description
name	String Service parameter name.
description	String Service parameter description.
type	String Service parameter type. Valid values are "String", "Boolean", "Number", "HTML", "JSON", and "Password".
value	Variable type - dependent on type. Service parameter value.
filePath	String Service parameter value loaded from the specified path.
fileIncludes[]	String A list of groovy script source files to prepend to the Groovy service script file when packaging.
bind	Boolean Specifies whether to inject the service parameter into the Java service object.
readOnly	Boolean Specifies whether the service parameter is read only on the server and cannot be edited in Journey Manager.
required	Boolean Specifies the service parameter is required to create the Java service object.
clearOnExport	String Specifies the service parameter value will be cleared when exported from a JM system.
unitTest	String Specifies the service parameter is for unit testing only.

As a minimum, you need to specify the parameter attributes name, type, value and bind. Always set the bind attribute to false if you are creating an arbitrary service parameter.
