Dialogs
When naming an intent trigger, keep in mind that you are not allowed to use more than 45 characters. Naming intent triggers is important because, in case of disambiguation, this name appears as an option.
Whenever you use a condition, you must add at least one rule and attach a response (action) or you will not be able to save your changes.
The field inside an intent trigger cannot be empty. If it is empty, you will not be able to save the changes. Consider converting the intent trigger to an event trigger if you encounter this issue.
To attach a new file in a dialog, ensure that the file is accessed through a URL. If you want to use a photo or video, make sure the file is accessed through a URL. For carousels, the title’s maximum length is 32 characters and the subtitle’s is 80 characters. You can have a maximum of 3 buttons per card and 6 cards. The Carousel’s title, Button’s Label, and Postback are mandatory fields.
Always remember that when you save your changes, they are not visible to the end user. To make them visible, you must Publish them.
