Message settings

These settings define the message type. Supported types include Text, Media, Interactive Message, Product Message, and Template Message.

Text

The Text type sends a plain text message. You must define the message content, which can include variables.

Media

The Media type sends a media file. Supported media types are Image, Audio, Video, File, and Location. For Location messages, you must specify the longitude and latitude. For all other media types, you must provide a URL for the media file.

WhatsApp media types and size limits:

Interactive

Interactive messages support two formats: Reply Button and List.

Message	Description	Example
Reply Button	An interactive message with up to three buttons. If you enable the header and footer, you must provide content for them. The maximum length for each is 60 characters. The message Body is required and supports variables. The maximum length is 1,024 characters. Click Add Button to define a Button Name. The name is limited to 20 characters.
List	Header/Footer: Optional, with a 60-character limit each. Set message body: The message body supports variables. The maximum length is 1,024 characters. Set list message button name: Supports variables. The maximum length is 20 characters. Set sections and items: You can add multiple sections, but the total number of items across all sections is limited to 10. Each section requires a Section Name (max 24 characters). Each item requires an Item Name (max 24 characters). The Item Description is optional. The maximum length is 72 characters.

Product

Product messages can be either Single Product or Multiple Products messages. The difference is that a single-product message supports only one item ID, while a multi-product message supports multiple item IDs and allows you to create sections for the items.

The Catalog ID and Retail ID (the ID of an item in the catalog) are provided by Meta Commerce Manager. To get these IDs, go to Meta Commerce Manager, select your account and the shop you want to use, and then click Catalog > Items to view the required ID information.

Template

To send a Template message, select a channel and a message template, both of which must be approved. Click Preview to view the selected template content.

Timeout settings

You can enable the Undelivered and Unread branches. If enabled, set a timeout and add components to these branches to handle messages that are not delivered or read within that time. For example, if a message is not delivered within the timeout period, you can use the Send SMS Message component as a fallback.

Interactive reply settings

Note

This setting applies only to messages of the Interactive Message type.

Configuration	Description	Example
Enable branching based on interactive replies	If enabled, this creates a branch for each button or item, allowing you to define a separate path for each user reply.
Enable branching for interactive reply wait timeout	If enabled, this creates a "Not Replied" branch to handle cases where a user does not reply in time. You must set a custom timeout in the Wait Time for Interactive Reply field. If this branch is enabled but left empty, the flow proceeds to the next component after the timeout.
Wait time for interactive reply	Set the timeout period. The unit can be seconds, minutes, or hours. After the timeout period is reached, the configuration in the "Not Replied" branch is executed.	-
Custom output variable name	Define a custom variable to store the user's reply. This variable is then added to the list of available variables for use in subsequent steps of the flow.	-

Advanced settings

Parameter	Description
Status Report	If you enable the Status Report feature, you must provide a URL to receive status reports.
