Hi,
1. Yes, I think i've been doing everything correctly to generate refresh
token
2. Yes, I've been using java client library for making api requests. To
make it easier i'll share some code about how i generate refresh token
*Client Side Javascript Code(For authorizing on behalf of the user)*
gapi.auth2.getAuthInstance().grantOfflineAccess().then(function(resp) {
//pass resp.code to my servlet
}
*Server Side Java*
GoogleAuthorizationCodeFlow authorizationFlow = new
GoogleAuthorizationCodeFlow.Builder(
new NetHttpTransport(),
new JacksonFactory(),
CLIENT_ID,
CLIENT_SECRET,
Arrays.asList(SCOPE))
.setAccessType("offline").build();
//Request token with offline access code
GoogleAuthorizationCodeTokenRequest tokenRequest =
authorizationFlow.newTokenRequest(offlineAccessCode);
tokenRequest.setRedirectUri(CALLBACK_URL);
GoogleTokenResponse tokenResponse = tokenRequest.execute();
*String refreshToken = tokenResponse.getRefreshToken();*
3. Here are java logs that are generated when the report downloading error
occurs
HTTP Response Code: 400, Trigger: Missing client information, Type:
ReportDownloadError.INVALID_PARAMETER
