Web-hook integration: payload missing the message contents

I have some notification templates mapped to following channels:

  1. Slack
  2. Webhook

I am getting the messages at slack, but at the webhook side I am receiving the data without the message contents. Here is the request payload I am getting at webhook:

Payload
"1628856875661":{
"brand":"0XNKQ5MM66M3E7G7VVME7ZCC46FR"
"data":NULL
"event":"ApplicationCreated"
"message":"1-6116622b-9dcb43088f5b5cb85ababd02"
"profile":{
"webhook":{
"authentication":{
"mode":"none"
}
"headers":{
"Content-Type":"application/json"
}
"method":"POST"
"profile":"expanded"
"url":"https://smee.io/webhook-url"
}
}
"recipient":"9b5a05f7-466b-4daf-b4fc-c3ee7adecb94.webhook_channel"
}

How to receive the actual message for webhook?

Thank you for the question. Keep in mind, that the Content from one Courier channel is not automatically populated across other channels in the template. You need to be sure that you configure the webhook payload in the webhook channel of the template designer.
