Looks like this whole endpoint wants the values in a nested web_hook param:
I’m not a huge fan of this nested format, and there are a few endpoints like this that are on my eventual list to fix. You can make an API call to it using form-data like so:
Notice how each parameter has the “array” syntax web_hook[payload_url]. If you are sending your request with json it will look like:
{
"web_hook": {
"payload_url": "https://example.com/hello",
"content_type": "1",
...
}
}
