Set up a message sequence with the String Builder

Use the String Builder, accessible for example from the Send Response action, to create a customized sequence of data type elements to build a string expression value. You can use any combination of data, expressions, prompts, and text elements.

How to use the builder

The following common operations are available in Architect builders that support multiple data types:

To build an expression value using a sequence of items of specific data types, click and configure the desired data types. Architect displays the added items as card elements within the sequence.
To rearrange the sequence of cards, click and hold the card that you want to move up or down in the list. Alternatively, use the Tab key to move through the list of cards and select the card that you want to move. To move the card to the desired position within the list, select Alt or Option and use the up and down arrow keys.
To delete a card, click the trash icon for the card that you want to delete. Alternatively, use the Tab key to move through the list of cards and select the card that you want to delete. Then, use the Delete key to delete the card.

Access the String Builder dialog box

Open the String Builder dialog box from a Send Response action’s Message Body. By default, the Message Body box is blank.

From a message flow’s task or state editor, drag a Send Response action into the appropriate location.
Under Message Body, click to open the message builder menu:
Select String Builder. The String Builder dialog box opens.

Set up the message body

Use message elements to set up a more complex ordered message sequence to send to the message recipient. You can include any combination of data, expressions, prompts, and text elements.

You can choose to direct Architect to analyze custom variables that you create. For example, find the message sender’s address or the time the message entered the flow. You can also include preset variables such as the conversation ID or the current flow version.

Click Data. Architect displays a Data field.
Click the Select variable list and choose the appropriate attribute.
Optionally add another data, expression, prompt, text, or string parsing element to the sequence.

Example:

Message.Message.senderAddress

In the Expression field, do one of the following:
- Type the expression.
- Click the keyboard button and open the large expression editor. Use the Expression help or other element tools to configure the full expression.
Optionally add another data, expression, prompt, text, or string parsing element to the sequence.

Examples:

Message.ConversationID
Flow.StartDateTimeUtc
Flow.Version
Append(“Hello “, “Message.Message.senderAddressInfo.name“)
ToDisplayString(Flow.AccountBalance)

Add a prompt to the message sequenceClick to expand

Select a prompt to display its associated text, or add one from the dialog box.

Click Prompt. Architect displays a Prompt field.
Do one of the following:
- Click Select a prompt and choose the appropriate prompt from the list.
- Switch to the expression builder and type the appropriate prompt.
Choose to display the Text or Text to Speech wording associated with the prompt.
Optionally add another data, expression, prompt, text, or string parsing element to the sequence.

Note: To upload a new prompt, click the + button. The Create Prompt dialog box opens. For more information on recording prompts, see Work with call prompts.
