Did you try this URL
https://oauth2.googleapis.com/token ?
Personnaly, I never put space in parameters. But I don’t know if this can broke something.
You can consider sending the request to a requestbin.com endpoint for testing and debugging

In addition your body should be a Json object for a post like you’ve shown. You’rs is in a query string format which won’t work. It tries to send a badly formed Json object which is unexpected and not needed. This is likely the badly formed request issue you’re experiencing.
