Having trouble with Google Chat and HubSpot connection

I’m trying to connect my HubSpot automation to a Google Chat room using webhooks. I followed the same steps that worked at my previous job but keep getting errors.

The HubSpot team says the issue is on Google’s side. Here’s what I’m seeing:

{
  "error": {
    "code": 400,
    "message": "Invalid JSON payload received. Unknown name \"Content\" at 'message': Cannot find field.",
    "status": "INVALID_ARGUMENT",
    "details": [
      {
        "@type": "type.googleapis.com/google.rpc.BadRequest",
        "fieldViolations": [
          {
            "field": "message",
            "description": "Invalid JSON payload received. Unknown name \"Content\" at 'message': Cannot find field."
          }
        ]
      }
    ]
  }
}

Basically I created the webhook in HubSpot and pasted the Google Chat webhook URL from my space. The workflow triggers but fails every time with this JSON error.

Anyone know what field names Google Chat expects? The error mentions “Content” field not being found.

hey, i had the same prob! you gotta change “Content” to “text” in your json. try this: {“text”: “your message here”}. that worked for me when i set up my webhook!
