Hi @paul-591970
Seems I can only embed one media item as a new user
There are not restrictions on free Pipedream Developer accounts when it comes to HTTP payloads to webhooks. I’m not sure what you’re referring to.
Perhaps HA isn’t sending the data you expect it to?
In your second screenshot here you show a different HTTP request. The first is a POST request containing data the body of the request, the second request is a GET request without a body.
The other thing I noticed was that with the webhook trigger, someone could potentially spam the URL with no payload and this would result in the daily quota being exceeded quite easily.
Each webhook URL is randomly generated to help with this issue, you can add a filter to help protect your webhooks by passing a secret key in the header of the request.
