Trigger

It helps to trigger the robots to execute the automation requests for a specific automation processes type.

This activity is relevant to only the Load Generator Process type.

The Load Generator Process in Automation Studio can be used to configure pre-massaging of data, create automation requests with relevant search criteria and for sending automation requests to AssistEdge Listener. See Load Generator Process section to know the related details.

Prerequisite

Using Trigger Activity

1.    In the Canvas Tools pane, click Process Components to expand the tool and view the associated activities.

2.    Drag the Trigger activity and drop on to the Flowchart designer on the Canvas.

3.    In the Browse for Profile list, select the profile to which the required automation process workflow is mapped. Only those profiles are listed to which the mapped automation process workflows are deployed.

4.    In the Browse for Process list, select the automation process workflow for which you want to create the trigger or automation request.

5.    In the Select REST API list, select the available listener application to which the automation requests must be sent.

6.    In the Transaction Expiration (seconds) list, select the available parameter holding the expiry time of the automation requests specified in seconds. You must define the parameter in the Parameter bar use this option.  Alternatively, you can manually enter the expiry time in the Transaction Expiration (seconds) field.

7.    Select the Wait for Completion check box to create a synchronous automation request. A synchronous request signifies that only one request gets executed at a given point of time and the robot returns the JSON output. If this check box is not selected, an asynchronous request gets created and the JSON output of the Listener API is received.  You can map the JSON output in the Output Parameter dialog box to receive either of the JSON outputs. Additionally, you can define a JSON query of the Listener API or the robot to receive data of a particular JSON query in the Output Parameter dialog box.

8.    Select the Retry Transaction check box to retry execution of the created automation requests, that have timed out or faced an exception during execution. If the check box is not selected, the retry is not attempted.

9.    In the No. of Retries list, select the parameter holding the value of the number of times the automation request must be retried for execution. The automation request is retried until it gets successfully executed or for the configured number of times.

10.  In the Retry Intervals (second) list, select the parameter holding the value of interval at which the retry of the execution of the automation request must be done. The time interval must be specified in seconds.

11.  Click the (Settings) icon, and then click Input Mapping to align the parameters of the automation process workflow with the parameters of the Load Generator Process workflow.  The Process's Arguments Mapping dialog box appears. The parameters that can be mapped with the Load Generator Process are available for selection. You must define the parameter and the value that must be mapped, in the Parameter bar to use this option. See the sample mapping in the following screen shot:

The Argument, Argument Direction and Argument Type lists the details related to the parameters of the automation process for which you want to create the automation request.

12.  In the Map to Parent list, select the load generator parameter that you want to assign to the automation process parameter. Repeat this step for each of the parameter you want to map.

13.  Click CONFIRM. You are directed back to the Trigger activity in the Canvas.

14.  Click the (Settings) icon, and then click Output Mapping. The Output Parameters dialog box appears. This lets you verify the output and other properties of the Listener API or the robot as per the configuration done.

15.  Click Add to align the JSON output received either from the Listener API or from the robot after the automation request of the selected process is executed.

16.  In the Parameter column, click Select or Add to select an existing parameter from the available list or create a new parameter. The Add new Argument dialog box appears.

a.    In the Argument Name field, enter a desired name.

b.    The DataType list, select the type of data. Available options are:

o          Text - A sequence of character, either as a constant or a variable.

o          Numeric - An integer type that range from negative through positive.

o          Decimal - An exact numeric value defined by its precision and scale.

o          Boolean - A data type used for making decision. Can have only two values- true or false.

o          DataTime – A data type used for values that contain date and time both.

c.     Click CONFIRM to save the argument details.

17.  In the JSON Selector field, enter the JSON query of the information that you want to retrieve from the JSON output of the Listener API or the robot, depending on the status of the Wait for Completion check box.

·       If a parameter is mapped but the JSON Selector is left blank, either the complete JSON output of the Listener API or the robot is received, depending on the status of the Wait for Completion check box.

18.  Click CONFIRM to save the mapping.

The Trigger activity with the name of the process selected, is created.
