Share downloadable files with google drive api

Files stored on My Drive can be shared with other users, but ownership of the content remains specific to an individual user. OAuth 2. If your application uses Google Sign-in , it handles the OAuth 2. Shared drive A Google Drive storage location that owns files that multiple users share to collaborate. Any user with access to a shared drive has access to all files it contains. Users can also be granted access to individual files inside the shared drive. Search for files and folders stored in Google Drive.

Create complex search queries that return any of the file metadata fields in the Files resource. Let users share files, folders and drives to collaborate on content. Create third-party shortcuts that are external links to data stored outside of Drive, in a different data store or cloud storage system.

Organizers of a shared drive can move items from that shared drive and into their own "My Drive" which transfers the ownership to them. Except as otherwise noted, the content of this page is licensed under the Creative Commons Attribution 4. For details, see the Google Developers Site Policies.

Permission propagation Permission lists for a folder propagate downward and are inherited by all child files and folders.

Capabilities The permission resource doesn't ultimately determine the current user's ability to perform actions on a file or folder. Create a permission The following two fields are necessary when creating a permission: type. To create a permission: Use the Permissions. In the request, identify the type and role. If the type is user or group , provide an emailAddress.

If the type is domain , provide a domain. Retrieve all permissions for a file, folder, or shared drive Use the Permissions. Verify user permissions When your app opens a file, it should check the file's capabilities and render the UI to reflect the permissions of the current user.

Determine the source of the role for shared drive files and folders To change the role on a file or folder, you need to know the source of the role. This field enumerates all inherited and direct file permissions for the user, group, or domain. Change permissions To change permissions on a file or folder, change the assigned role.

To change the assigned role: Call permissions. In the request, identify the new role. A resumable upload allows you to resume an upload operation after a communication failure interrupts the flow of data. Because you don't have to restart large file uploads from the start, resumable uploads can also reduce your bandwidth usage if there is a network failure.

Resumable uploads are useful when your file sizes might vary greatly or when there is a fixed time limit for requests mobile OS background tasks and certain AppEngine requests.

You might also use resumable uploads for situations where you want to show an upload progress bar. In addition, it includes a Location header that specifies the resumable session URI:. You should save the resumable session URI so you can upload the file data and query the upload status. A resumable session URI expires after one week. If you have metadata for the file, add the metadata to the request body in JSON format.

Otherwise, leave the request body empty. In addition, the response includes a Location header that specifies the resumable session URI.

Use the resumable session URI to upload the file data and query the upload status. Upload the content in multiple chunks. Use this approach if you need to reduce the amount of data transferred in any single request. You might need to reduce data transferred when there is a fixed time limit for individual requests, as can be the case for certain classes of Google App Engine requests.

This approach is also useful if you need to provide a customized indicator to show the upload progress. Add the chunk's data to the request body. Create chunks in multiples of KB x bytes in size, except for the final chunk that completes the upload. Keep the chunk size as large as possible so that the upload is efficient. Send the request, and process the response. If the upload request is interrupted, or if you receive a 5xx response, follow the procedure in Resume an interrupted upload. Repeat steps 1 through 4 for each chunk that remains in the file.

Use the Range header in the response to determine where to start the next chunk. Do not assume that the server received all bytes sent in the previous request. When the entire file upload is complete, you receive a OK or Created response, along with any metadata associated with the resource. If an upload request is terminated before a response, or if you receive a Service Unavailable response, then you need to resume the interrupted upload.

Add a Content-Range header to indicate that the current position in the file is unknown. If you received a Resume Incomplete response, process the response's Range header, to determine which bytes the server has received.

If the response doesn't have a Range header, no bytes have been received. Now that you know where to resume the upload, continue to upload the file beginning with the next byte. Include a Content-Range header to indicate which portion of the file you send. When you create a file in Google Drive, you might want to convert the file into a Google Workspace file type, such as a Google Doc or Sheet. For example, maybe you want to convert a document from your favorite word processor into a Google Doc to take advantage of Google Doc's features.

To convert a file to a specific Google Workspace file type, specify the Google Workspace mimeType when creating the file.

To see if a conversion is available, check the About resource's importFormats array prior to creating the file. Supported conversions are available dynamically in this array.
