If the command prompt is not recognizing pip, move the requirement files to the scripts folder and run the command C:\Python37\Scripts\pip install -r twilio.txt.

Design the Action steps for Twilio Node

In the Actions tab, you can define actions to be performed in Twilio Processing Node.

Click the Twilio node to open the attributes pane. In the Actions tab, select one of the following options from the first drop-down:

• Twilio Functions: To select the required Twilio Functions from the list in the second drop-down.
• Custom Twilio Function: The Custom Twilio functions are created for specific needs if not met by the Predefined Twilio functions. All the User Defined Functions created in the HyperApp with Type selected as Twilio gets listed in the drop-down.

• Set Variable: To set the value for a Variable as needed in further steps. The value set can either be a constant or another variable. If this variable is toggled as an output variable in the Variables tab, it can be mapped to succeeding nodes of the task.

Variables

All Input/Local variables of the Twilio node are displayed under the Variables tab.

Table Definition

All Default/Custom DataTables in the task are displayed under the Table Definitions tab.

Properties of the Twilio Node

1. Navigate to Properties and enter Name and Description.
2. Enable Mark run Failure on Node Fail and Continue on Failure? options as required.
