how can I deeplink an app from Google Assistant?

Question

I'm creating a dialogflow agent integrated with Google Assistant. What I'd like to do is to open an app (my app) when a proper intent is matched. I've seen that actions like Youtube, Spotify etc. are able to do that, for example I can tell the Youtube action "search for cats video" and the Youtube app will open with a list of cats videos. I tried to use the DeepLink class but I then noticed it's deprecated. DeepLink class Is there any way you can suggest me to do this? Thanks in advance

I think you are looking for App Actions. Here are the steps you need to follow:

1. Find the right built-in intent. actions.intent.OPEN_APP_FEATURE should be the right one for you.

2. Create and update actions.xml. It should look like

    <?xml version="1.0" encoding="UTF-8"?>
    <!-- This is a sample actions.xml -->
    <actions>
        <action intentName="actions.intent.OPEN_APP_FEATURE">
            <!-- Use url from inventory match for deep link fulfillment -->
            <fulfillment urlTemplate="{@url}" />
            <!-- Define parameters with inventories here -->
            <parameter name="feature">
                <entity-set-reference entitySetId="featureParamEntitySet" />
            </parameter>
        </action>
        <entity-set entitySetId="featureParamEntitySet">
            <!-- Provide a URL per entity -->
            <entity url="myapp://deeplink/one" name="featureParam_one" alternateName="@array/featureParam_one_synonyms" />
            <entity url="myapp://deeplink/two" name="featureParam_two" alternateName="@array/featureParam_two_synonyms" />
        </entity-set>
    </actions>
