Google Slides Error

I am new to Google Slides API.
I followed the steps in their QuickStart example at https://developers.google.com/slides/quickstart/java and that runs fine.
I am now trying to create a presentation by following the steps at https://developers.google.com/slides/how-tos/presentations and getting the following error when running the code.
com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden

"code" : 403,

} ],

}

at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.execute(AbstractGoogleClientRequest.java:469)
This occurs when I try to create the presentation. Any ideas how to resolve this?
All the best

Notice this part of the documentation.
You can also create a blank presentation using the Google Drive API
Files.create
method, specifying application/vnd.google-apps.presentation as the
mimeType. You'll need an appropriate Drive API
scope
to authorize this call. You'll need an appropriate Drive API scope to
authorize this call.

How to specify a disk type for workers in Google Dataflow?

In the doc there is a option workerDiskType but I can't make it work. I tried to use persistent SSD. Each time I try something I get a 400 http code without explanation.
I tried all of those values:
zones/$ZONE/diskTypes/pd-ssd
zones/$ZONE/disks/pd-ssd
projects/$PROJECT/zones/$ZONE/diskTypes/pd-ssd
projects/$PROJECT/zones/$ZONE/disks/pd-ssd
What is the correct format? Does this option works?
The answer I have from Dataflow is not really helpful:
{
"code" : 400,
"errors" : [ {
"domain" : "global",
"message" : "Request contains an invalid argument.",
"reason" : "badRequest"
} ],
"message" : "Request contains an invalid argument.",
"status" : "INVALID_ARGUMENT"
}

"compute.googleapis.com/projects//zones//diskTypes/pd-ssd" is the correct identifier for SSDs

Google Cloud Storage Java API - Deleting a file

How do I set a "WRITER" permission on a GCS bucket?
I am trying to delete a file on cloud storage using:
cloudstorage.objects().delete(bucket, object).execute();
and get the following error:
{
"code" : 403,
"errors" : [ {
"domain" : "global",
"message" : "Forbidden",
"reason" : "forbidden"
} ],
"message" : "Forbidden"
}

With gsutil, like this:
gsutil acl ch -u email#address.com:W gs://bucket-name
Alternately, you can go to the Developer's Console, head over to storage > Cloud Storage > Storage browser, click on the "...", then "edit bucket permissions", then click "+ Add item", choose "user", the email address, and Writer, then click "Save".
Alternately, you can do this programmatically with the JSON API, using the storage.bucketAccessControls.insert method.

Google Drive setWritersCanShare(false) and update of a File in JAVA

I'm trying to put the option "setWritersCanShare" of a file to FALSE. Now I am the owner of the file and I want that the file editors can't share the File. I can get the file and change its permission (via API) without problmes, but when I try to change the "setWritersCanShare" option, I get this response:
{
"code" : 403,
"errors" : [ {
"domain" : "global",
"location" : "Authorization",
"locationType" : "header",
"message" : "The authenticated user does not have the required access to the file 0B0o1ZH_FIoLGUER2UFptYi1CVEU",
"reason" : "userAccess"
} ],
"message" : "The authenticated user does not have the required access to the file 0B0o1ZH_FIoLGUER2UFptYi1CVEU"
}
This is the file update code:
Drive service = new Drive.Builder(httpTransport, jsonFactory, null).setHttpRequestInitializer(credential).setApplicationName("La fiesta").build();
File file = service.files().get(fileID).execute();
file.setWritersCanShare(false);
File fileUpdate=service.files().update(fileID, file).execute();
What it's my error?
Thanks and regards

Try the operation in the Google API Explorer and see if the result is the same.
The error seems to indicate that the authenticated user isn't actually the owner of the file. Are you sure you're authenticating as the file owner (not a Service Account)?

OAuth2 and Drive API, can't list/retrieve files

I have a web application that needs to list all files from my Google Drive and then fetch them when clicked.
I use OAuth for authenticating and it seems to work (the same code works well with Calendar API). I tried different scopes in serviceAccountScopes with no avail.
Basically authentication is:
credential = new GoogleCredential.Builder().
setTransport(HTTP_TRANSPORT).
setJsonFactory(JSON_FACTORY).
setServiceAccountId(apiEmail).
setServiceAccountScopes(DriveScopes.DRIVE).
setServiceAccountPrivateKeyFromP12File(p12File).build();
credential.refreshToken();
service = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential).
setApplicationName("My API").build();
edit: I should Add that credential's accessToken is null before refreshToken() call.
After that I try:
FileList files = service.files().list().execute();
The returned FileList is (should contain items):
{"etag":"\"_U9FTLXcHskmKgrWAZqJlfW8kCo/vyGp6PvFo4RvsFtPoIWeCReyIC8\"","items":[],"kind":"drive#fileList","selfLink":"https://www.googleapis.com/drive/v2/files"}
If I check that selfLink the contents is:
{
"error": {
"errors": [
{
"domain": "usageLimits",
"reason": "dailyLimitExceededUnreg",
"message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.",
"extendedHelp": "https://code.google.com/apis/console"
}
],
"code": 403,
"message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."
}
}
Daily limit is not an issue here. (I guess this has nothing to do with this issue, since: https://stackoverflow.com/a/10639679/2090125). Also, I have enabled Drive and Drive SDK in Console (https://stackoverflow.com/a/10329353/2090125).
When downloading a file this is performed:
File file = service.files().get(fileId).execute();
And it produces this (fileId exists):
An error occured: com.google.api.client.googleapis.json.GoogleJsonResponseException: 404 Not Found
{
"code" : 404,
"errors" : [ {
"domain" : "global",
"message" : "File not found: 0B97KF40kTwrTaTllMnZCTV9ZSnM",
"reason" : "notFound"
} ],
"message" : "File not found: 0B97KF40kTwrTaTllMnZCTV9ZSnM"
}
And again when checking https://www.googleapis.com/drive/v2/files/0B97KF40kTwrTaTllMnZCTV9ZSnM the same "dailyLimitExceededUnreg" is seen.
What is going on here, is there a problem in my authentication? Should I configure Drive Integration in Drive SDK somehow? From Googles documentation I have understood that it's not necessary and the methods I'm using should work without further configuring.
