* Task name: Specify the name of the task.
* Phone number: Type or select phone number from the data payload. For example, `BillToContact.MobilePhone` . You can specify multiple phone numbers, and the messages will be sent to all numbers.
* SMS message: Enter the SMS message template. For example:

  ```
  Hello {{Data.BillToContact.FirstName}}, your recent payment for subscription {{Data.Subscription.Id}} has failed. Please update your payment method at https://www.sampleComp.com/account/123456/payment-methods-update to avoid service disruption.
  ```
* Task tags (Optional): Specify a task tag that will be used for searching and filtering tasks via the UI or API.
* Paths of data payload values to delete (Optional): You can delete data that is not needed to reduce task payload size and improve performance. The payload path is in the format of `Data.<objectName>` .
* Concurrency Mode: Controls whether Workflow processes tasks in a single or multi-threaded manner for this task type. Select **Sequential** to single-thread, or **Parallel** to allow multi-threaded processing.

  If you select **Parallel**, the **Max Concurrency** setting controls the maximum number of threads for this task type that can be utilized. You can specify a value from 1 up to the allowed maximum for this task type. A value of 1 behaves the same as Sequential processing.
