[Dialogflow]Update Permission through Webhook format (for push notifications) - php

Question

ORIGINAL REQUEST: I'm trying to implement the push notifications following the documentation: https://developers.google.com/actions/assistant/updates/notifications
I'm using Dialogflow with webhooks (in PHP) and the documentation is giving example in nodeJS
Right now, i'm blocked because of the Update permission, here's my Webhook response :
{
"source": "webhook",
"payload": {
"google": {
"expectUserResponse": true,
"systemIntent": {
"intent": "actions.intent.PERMISSION",
"data": {
"#type": "type.googleapis.com/google.actions.v2.PermissionValueSpec",
"permissions": [
"UPDATE"
]
},
"updatePermission": {
"intent": "notification.simple.text"
}
}
}
}
}
When I do the simulation, asks me a permission for a push, but not for the intent I specified.
I'm quiet sure that the problem is the updatePermission, something must be wrong with that:
Is it the field name?
In intent, i put the intent name that i filled in dialogflow, maybe do i have to an use action? Is it in the good format ?
If someone can help me or just give me an example of a clean response for an update permission.
Thanks!
Solution
I just found why, my json wasn't good, the updatePermissionValueSpec must be into data object.
{
"source": "webhook",
"payload": {
"google": {
"expectUserResponse": true,
"systemIntent": {
"intent": "actions.intent.PERMISSION",
"data": {
"#type": "type.googleapis.com/google.actions.v2.PermissionValueSpec",
"permissions": [
"UPDATE"
],
"updatePermissionValueSpec": {
"intent": "notification_simple_text"
}
}
}
}
}
}

I believe updatePermission should be named updatePermissionValueSpec.
Example response:
"payload": {
"google": {
"expectUserResponse": true,
"richResponse": {
"items": [
{
"simpleResponse": {
"textToSpeech": "PLACEHOLDER"
}
}
]
},
"systemIntent": {
"intent": "actions.intent.PERMISSION",
"data": {
"#type": "type.googleapis.com/google.actions.v2.PermissionValueSpec",
"permissions": [
"UPDATE"
],
"updatePermissionValueSpec": {
"intent": "intent_name"
}
}
}
}
}
