Include the data in the HTTP body section. As the error states your grant request is not valid. grant_type will look like grant_type: urn:ietf:params:oauth:grant-type:jwt-bearer or grant_type: refresh_token before encoding. The first is for requesting an access token the second for renewing an existing access token with a refresh token. — John Hanley

Bad Request error occurs when the request syntax are wrong (i.e. when a parameter or a header you are supposed to send is missing or contains an incorrect/invalid value). Best option is to check OAuth Specification are figure out what you have done wrong in the token request. Google might have a slightly different implementation from the actual specification, but I think it won't be difficult to find the issue after checking the documentation.

Access token request specification for authorization code grant can be found here.
