How to create a custom response depending on an entity?

I have a list of specific entities, how do I set an individual response for each one? or a list to responses for specific entities?

I was thinking maybe it could be achieved through the Google assistant custom payload(?)

Late response, but maybe someone will find this answer useful if you prefer not having to use fulfillment webhooks and you only need to utilize one parameter.

Your question is somewhat vague, but it sounds like you will have a parameter in an Intent set to some value, those values coming from a custom Entity type, and you want a different response for each value.

You can't handle this through the Response section of the Intent - you need to use a fulfillment webhook.

If you're using the actions-on-google library (which you suggest you might be using), and the parameter was named val, then the code fragment might look something like this:

app.intent('choose.value', (conv, {val}) => {
  switch( val ){
    case 'red':
      agent.add('I like red too!');
      break;
    case 'blue':
      agent.add('Blue is pretty cool!');
      break;
    default:
      agent.add(`Not sure what to say about ${val}.`);
  }
})

If you are using the dialogflow-fulfillment library, it would be something like:

var chooseVal = function( agent ){
  var val = agent.parameters.val;
  switch( val ){
    case 'red':
      conv.ask('I like red too!');
      break;
    case 'blue':
      conv.ask('Blue is pretty cool!');
      break;
    default:
      conv.ask(`Not sure what to say about ${val}.`);
  }
}

If you are using multivocal, you can add a builder that sets the Outent environment setting based on the color, and set the responses for the Outent and the Intent in the configuration:

new Multivocal.Config.Simple({
  Local: {
    en: {
      Response: {
        "Outent.red": [
          "I like red too!",
          "Red is nifty."
        ],
        "Outent.blue": [
          "Blue is pretty cool!",
          "I really groove blue"
        ],
        "Intent.choose.value": [
          "Not sure what to say about {{Parameter.val}}"
        ]
      }
    }
  }
});

var outentBuilder = function( env ){
  env.Outent = `Outent.${env.Parameter.val}`;
  return Promise.resolve( env );
};
Multivocal.addBuilder( outentBuilder );
