@Marvin i have a webhook with this template
Copy code
{
  "event": "pim.unifyd.catsy",
  "resource": {
    "prefect.resource.id": "pim.unifyd.catsy.handle",
    "payload": "{{ body }}"
  }
}
how to update so that it will accept a json str as body- currently it throws a 400
m
✅ thought for 43.8 seconds
Based on the research, I can help you fix your webhook template to properly handle JSON payloads. The issue is likely that the 
{{ body }}
template variable needs to be properly escaped as JSON. Here's the corrected template:
Copy code
json
{
  "event": "pim.unifyd.catsy",
  "resource": {
    "prefect.resource.id": "pim.unifyd.catsy.handle",
    "payload": {{ body | tojson }}
  }
}
The key change is using the 
tojson
Jinja2 filter (
| tojson
). This filter ensures that: 1. The JSON string is properly escaped 2. The resulting webhook template produces valid JSON 3. The payload maintains its JSON structure rather than being treated as a plain string If you're sending the webhook request programmatically, make sure to: 1. Set the 
Content-Type
header to 
application/json
2. Send the body as proper JSON, not a string representation of JSON For example, if you're using Python requests:
Copy code
python
import requests
import json

payload = {
    "some_key": "some_value"
}

response = <http://requests.post|requests.post>(
    "your_webhook_url",
    json=payload,  # This automatically sets the correct Content-Type header
    headers={
        "Accept": "application/json"
    }
)
If you're still getting a 400 error after making these changes, please share: 1. An example of the JSON payload you're trying to send 2. The method you're using to send the webhook (curl, Python, etc.) This will help me provide more specific guidance.
