I've been developing on Actions on Google using Dialogflow. The webhooks worked like charm when using the simulator for testing.
I published an Alpha released but it isn't working at all. The Alpha testers can't get it connect and when I tested that Alpha version on the simulator, it tells " isn't responding right now. Try again soon."
In the documentation "Releasing Your Actions to Alpha and Beta Environments", a paragraph reads: "Implement fulfillment for alpha/beta releases The release channel information is not included in the HTTP request from the Assistant to your fulfillment. To handle release channels in your fulfillment, you should provide different fulfillment URLs (for example, one fulfillment URL for the beta and another URL for the production version of your Action)"
I searched everywhere and I could not find any pointers on how to implement a new fulfillment for the Alpha (and eventually the published release). I have one url that I use in the fulfillment on Dialogflow, so how can I do otherwise?
