How to route to another datastore without having user re ask question

[Ian_Stack]

From my my Start Page in Dialogflow CX (DF), I route it to my 'intent' page.  Here I have multiple routes along with a datastore attached.  One of the routes direct the conversation to another page, we call it Page 2,  with a different datastore.  This is because this datastore has different content and is better suited to answer certain types of question

Problem:  When the intent is triggered from the 'intent' page to 'Page 2', it correctly transitions to this page, however the question asked is not picked up by the datastore on 'Page 2.' 

How do I route from page to another, that each have different datastores, without any disruptions in the flow.

For example, if 'Page 2' is triggered by the intent of 'What products do you offer?' I want 'Page 2's' datastore to pick up this question and answer it.  Currently it routes it to 'Page 2' but doesn't answer the question. Just a blank response

as of today, there is no way of transitioning + hitting a datastore at the same time. the only way to achieve it is by calling the datastore in a webhook in the new page or use a playbook

Do you know how I can create a webhook to access the datastore? I don't see any examples or documentation on how this done?

yup, you have to use the discoveryengine API: https://cloud.google.com/generative-ai-app-builder/docs/samples/genappbuilder-multi-turn-search?hl=e...
