Actions are, well, actions your bot executes at specific time in the skill execution.

Action categories

An action can either be:

  • a message to send back to the user
  • an HTTP call to your API
  • the redirection and execution of another skill
  • an edition of the memory of the bot for the current conversation
  • a switch to another language

Message actions

For message actions, all rich messaging formats are supported.

Recast.AI - Messages types

Formatting: You can inject variables in your messages by using the double braces syntax. For example, {{nlp.source}} will be replaced by the input sentence.

Here is a list of the more useful ones:

  • {{nlp.source}}: raw user input.
  • {{nlp.entities.location[0]}}: first entity detected of the type location. You can replace location by any entity name you want.
  • {{#location.raw}}: same as above, get the first entity location detected, and get its raw field.
  • {{nlp.sentiment}}: sentiment of the sentence
  • {{nlp.act}}: act of the sentence
  • {{nlp.type}}: type of the sentence
  • {{nlp.intents[0].slug}}: slug of the first intent detected
  • {{memory.person.raw}}: a value stored in the memory of the bot. Here person is the alias of a requirement
  • {{skill}}: slug of the current skill
  • {{skill_occurrences}}: number of consecutive occurrences of the current skill

HTTP actions

For webhooks (HTTP actions) you can either provide a full url, or simply a route that is added to your bot's base url (updatable in your bot settings).

Recast.AI - Webhook action

When your url is called, you receive the complete state of conversation:

 "conversation": {
   "language": "en",
   "memory": {
     "person": {
       "fullname": "Francois",
       "raw": "Francois",
       "confidence": 0.95
   "skill": "small-talk",
   "skill_occurences": 1,
   "participant_data": {}
 "nlp": {
   "source": "hi",
   "intents": [
       "slug": "greetings",
       "confidence": 0.99
   "sentiment": "vpositive",
   "entities": {},
   "act": "assert",
   "type": null,
   "version": "2.10.1",
   "processing_language": "en",
   "language": "en",
   "uuid": "96597974-3ee1-4743-8a5d-341b67effb9a"
   "status": 200,
   "timestamp": "2017-10-25T21:36:02.071243+00:00",

You can send back messages you want to send to the user, as well as an updated conversation state.

Go to actions

You can use Goto action to indicate which skill should be executed next.

Recast.AI - Goto action

You have two options:

  • Start the skill will bypass the triggers of the skill and directly try to resolve the requirements and the actions.
  • Wait for the user input serves as an indicator, the next user input will try to enter this skill in priority, but triggers will be applied.

Note: you can use a variable instead of the name of the skill, as in the messages actions described above.

Language actions

This action allows you to modify the language of the conversation.

Recast.AI - Language action

It can be especially useful when your user asks "Can you speak Spanish?" for example.

Memory edition actions

Theses actions allow you to do three different things:

  • Reset the entire memory of the conversation
  • Set values in the memory
  • Unset a key in the memory

First the memory is reset, then the new values are set, and finally the specified keys are unset.

Recast.AI - Memory action

Note that you can also use variables, as in the messages actions described above.
