Is it possible to create records in multiple tables with a single webhook?

I don't have a lot of experience with Web-hooks, so somebody else might know how to make that happen, but I know you could do this with a Formula-URL field, combined with the API_AddRecord function.  
This would require somebody to push a button.  But I'm sure once the lead is qualified or converted to a client is when this happens anyway.  

So the button could do it all if needed.  (Won client, new Person, New address, New Job, New Car)
