How to identify health check request? - actions-on-google

Question

My app is getting health check about 10 health check request per hour, and that makes my conversation log messy.
Because of the health check does not have screen capability, our backend server response the request as Google Home is requesting.
Is there any way to detect if the request is health check request or not?

Answer 1

For starters, you should be responding as if it was a Google Home. You have to respond with valid output, or it will reject you. So don't try to be too fancy in your response - just use this to avoid cluttering your analytics and logs.
The health check will look like a normal welcome request. The ping will contain an argument named is_health_check with a boolValue of true and a textValue of 1. If you're using Dialogflow, this will be one of the arguments at originalRequest.data.inputs[0]. For the Actions SDK, it will be at data.inputs[0].
Here is a partial sample from Dialogflow:
{
"originalRequest": {
"source": "google",
"version": "2",
"data": {
"surface": {
"capabilities": [
{
"name": "actions.capability.AUDIO_OUTPUT"
}
]
},
"inputs": [
{
"rawInputs": [
{
"query": "Sample",
"inputType": "VOICE"
}
],
"arguments": [
{
"textValue": "1",
"name": "is_health_check",
"boolValue": true
}
],
"intent": "actions.intent.MAIN"
}
],
...
}
