Google Action How to add a parameter to the userresponse sent to my webhook

Question

I am working with google action on the google action console. i am able to communicate with my server and get some response with webhook. i am also able to send parameter using intent. But those parameter are prerecorded. it's can ether be a name that i choses before or a system predefined type like Date or number. But i would like to send a number that i can increment every time i call the webhook.

What i am trying to do is a list of video red with the media player. Problem is that i can use a playlist with the mediaobject but when i do that at the end of a video the next one start. But what i want to do is to ask to the user if he want to read the next video / replay this video or review the previous before starting it. So i would like to have a parameter videonumber that would be a int and after the first video end i would send it to the webhook and my server would send me the second video, at the end of the second video i would send 2 to the server. and so on to always get the next video...

More generally is there a way to send parameter to webhook for exemple is it possible to send a Boolean? I tried to add a parameter in intent but if the parameter is not said by the user, it would not be added to my Json sent to my server.

Is there a way to achieve this with google action?

It seems like what you are looking for is some sort of session storage. For the duration of the conversational session you will be able to set a collection of fields and properties in a JSON format which would include Number and Boolean types.

Between turns, you can set a field in session storage:

// Assign color to session storage
app.handle('storeColor', conv => {
  let color = 'red';
  conv.session.params.exampleColor = color;
});

And in a later intent, perhaps a follow-up intent, you can retrieve the value from the same place:

// Retrieve color from session storage
app.handle('getStoredColor', conv => {
  let color = conv.session.params.exampleColor;
});
