Webhooks as raw json

I got this support message from our lead generation system. Is there any way to post a webhook as a raw json? The normal way provides an Invalid Request error.

"Hi, that posting submission will not work since it is not submitting the JSON in the proper format that is allowed. The system actually recognizes this as a suspicious/hacking attempting, that is why you saw the error response for Invalid Request.

Is Unbounce able to submit JSON in a different format? If they have a way to insert a raw JSON it would be this:"

Hi @Daniel_Armao,

I’m not aware of a way to change the way webhooks deliver their payload.

However, you always have the option of writing your own backend script to accept the webhook, reformat it and send it to your lead generation system the exact way they can accept it.
