Flow Advanced: String templates

Within text replies, you can use params that are matched by the AI or collected using Triggers: Any Text.

If you have trained the AI to match entities, they can be used with a template syntax.
For example, if you trained the AI with an entity named "country", you will be able use it like so:

I am going to check the weather for {{country}}

This would result in a response like:

I am going to check the weather for France.

Param value

You can also access the match by using {{param.match}}

You can use string templates in several different replies:

• Text replies
• Titles and subtitles of a card
• Button labels

You have the option to select the elements that will be rendered. For example, to access the last element of the list , use param.last.match:

value: param.first.value, param.last.value, param.any_digit.value.
