Issuing HTTP Post with Automation

[Scott]

I've set up a Webhook with Make.com and formatted the URL to work with Trello. I've validated that I can open the webhook URL in my browser and receive a response. 

Now, whenever I set up an HTTP request automation, I always get an error 400, even if I have nothing in the payload. What's the secret to getting this to work? 

Thanks,

Scott

Looks like this was just a matter of the JSON formatting of the payload - I'm now submitting this successfully to make.com.
