The payload sent along the Dialogflow Webhook should include the a source that looks like so:
"originalDetectIntentRequest": {"source": "facebook",}
The user suggest we use something like below, so that it is known that it is coming from Rocketbots.
"originalDetectIntentRequest": {
"source": "rocketbots_fb",
}
or
"originalDetectIntentRequest": {
"source": "rocketbots_wa",
}
