Trying to get response using winhttpjs.bat but there is something wrong I'm doing #33

Hi
I'm Trying to get response from my website using your tool "winhttpjs.bat" but it's not working, what I'm doing wrong? sorry... I have poor knowledge about api and batch file.

files:
1-call.bat
call winhttpjs.bat https://*********** -method POST -body-file body.json -saveTo response.txt
2-body.json
{ "email":"****@****.***", "key":"*******************" }
3-and your tool: winhhtpjs.bat

when I run call.bat the cmd popup for a second and then an EMPTY response.txt file created!!
the email and key info are correct but for testing only.
