Get back lost leads after from

I created a form with the method “post” to an external URL instead of the “get”.
The “post” method was not correctly set up, therefore I loose some leads (I can see on google analytics that I got some leads but they don’t appear neither in the webflow backoffice (because it is only for “get” method", neither in my external URL (wrong set up)
My question is : is there any back up where I can get back thoses lost leads or are they lost forever ? :cry:
