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

Entity search matches can be fuzzy. By default, string templates print the value of a matched parameter.

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

Param selection

Within string templates, Matched params with the same name are appended and multiple params render as a list.

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:

The first element of the list can be accessed by param.first.match or param.0.match.

It also works with the following:

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


String templates also support advanced formatting filters. Supported filters include:

Mathplus, minus, modulo, times, floor, ceil, round, divided_by, abs
Stringappend, prepend, capitalize, upcase, downcase, strip,lstrip, rstrip, strip_newlines, split, replace, replace_first, remove, remove_first, truncate, truncatewords
Dateformat like strftime
