Conditional Processing or Execution Conditions gives you the power to decide if a particular action on Twilio will be performed or not when the workflow is triggered by the incoming event. This is akin to the ability to apply 'if-then-else' logic to the execution of an action based on the value of the attribute from the trigger event of the workflow.
Think of Conditional Processing as an equivalent of 'if-then-else', as decision diamond in the flow chart, or the Conditional Branching in BPEL (Business Process Execution Language).
You can add conditional processing to any action in your workflow and decide which actions should be performed in response to a particular trigger event identified by its characteristics or the data attributes. You can apply complex logic using AND, OR, and grouping of such conditions. Each of the conditions supports different operators based on the event data types like a string, number, boolean, etc. Read here to find more about Conditional Processing.
We will take a scenario where you are using Twilio as the trigger application. There could be multiple application actions attached to be invoked upon receiving a Twilio trigger. Each of the actions in the flow would apply its own execution condition based on the data attributes of the Twilio trigger event. This will allow each of the actions to independently choose to execute based on the defined execution conditions.
In this example, the workflow is triggered when a new SMS is received on any one of the outbound numbers configured with Twilio. It has a Smartsheet action.
When using Twilio as the trigger application, the following attributes will be available to you in all your actions:
- From Country - Country code of the Phone number from which the SMS will be received
- From City - City from which the SMS will be received
- From - Phone number from which the SMS will be received
- From Zip - ZipCode from which the SMS will be received
- To - Phone number on which the SMS will be received
- Body - Content of the SMS received
- To Country - Country code of the Phone number on which the SMS will be received
- From State - State from which the SMS will be received
In the figure below, in the same workflow, a message in Microsoft Teams action "Send Message to the Channel" will only be sent to a selected channel if the number on which the SMS is received contains "123".
