Please note that to show a card, you must have a title and at least one other factor, picture, subtitle or button. If you want to send card in WhatsApp channel, you will need to create “Carousel Template” and then use “Carousel template” instead. |
Send "For Each"
This message type is also showing cards but in a more automatic way. With "For Each", you don't need to type in each card yourself. It automatically displays all items in a JSON variable. Check Action Step - JSON Operation if you have no idea about what is JSON variable.

...
Key Name | Description |
|---|---|
INDEX | index of the item started from 1 |

For example, let's add a Send Message step, find the system field "SELECT":
...
click the row "item" to get the path "$.item" or type in the path directly
in the JSON path, add key name if needed. In this case, let's show the name of the selected item. So add ".name" after the path.

This feature is practical when your bot logic is complex and rely heavily on other servers.
For example, you have your own AI algorithm to analyze users' questions and calculate corresponding response on your server, in this case, you can send the question in the API request. And the server can generate a response based on the question. Finally, the server send the response back to UChat to display to your users.
