need a fake rest server which supports POST ,PUT methods which accepts headers and post/put body

I am testing an application which accepts http/https rest requests, for that I need few open source rest calls, where I can use POST, PUT calls which must use headers and POST/PUT body. Can anyone please share any link, where I can get such free apis to test. I found many such rest apis but those works irrespective of headers. Can anyone please share such api list which must need header and post body?

Thanks in Advance
