I need to authenticate to an API using OAUTH2, however, it has to be made programmatically, no user typing stuff in a browser is permitted.
This seems like such a simple use case, but I haven't found anything online, the only thing close to it was this post, and the only answer is "yeah, you don't want to use a web browser, but what if you do?"... This doesn't help.
So, please, opening a web browser is not an option, I just want to know if Google provides any way to authenticate purely through code.
Thank you!
In order to achieve your goal, I would like to propose to use the Service account. When the Service account is used, the access token can be retrieved without using the browser.
As the points for using the Service account, please check the following points.
The Service account is not your own Google account.
For example, as one of several situations, if you want to manage a file in your Google Drive using the Service account, please share the file with the Service account. By this, the Service account can access to the file in your Google Drive.

Several cases using the Service account
Google Drive Access - Service Account or OAuth - To read/write user files
Google service account not being authorized for calendar API
Service Account for google sheets returns not found

So I applied as a Twitter Dev to make a bot that tweets stuff. About two days later, I got access. When I ran the code with the tokens it gave me, it posts from my account.
My question: Is there a way for me to make it send as another account (a bot account) without me having to apply again?
Yes, you can use the Sign-in with Twitter flow to authenticate a different user to your app, and then use the Access Token and Access Token Secret for that user to post to that account. This is the correct way to implement things - you should not be applying for multiple developer accounts.
You can also use tools like twurl or another CLI tool to

Did you get elevated access from tweeter or Essential? I have a stack error:
You currently have Essential access which includes access to Twitter API v2 endpoints only.
If you need access to this endpoint, you’ll need to apply for Elevated access via the Developer Portal.
It's hard to get Elevated now.
I am attempting to connect a Google Assistant app using DialogFlow(Api.AI) with Firebase Auth. My App uses Firebase Auth to maintain user accounts and the realtime database to store data. I would like to be able to make changes to a user's data through the Google Assistant, maybe using something like a cloud function. In order to make any user changes through Google Assistant, I need to link the user's Google Assistant account with their Firebase Auth account. The current mechanism appears to be using an OAuth flow documented here.
The question I have is, what is the best way to accomplish this? Do I need to set up a custom OAuth server? There is a lot of documentation on Google's cloud website about OAuth, but it all appears to be related to using OAuth to access Google's APIs, and I can't really see a simple way to host this linking mechanism in GCP.
There is this question that is pretty close, but the difference I have is that I don't have an external API, I just want to authenticate my user and be able to modify their data in the realtime database.
Thank you for your help!

I want to upload files to Google Drive using the Google.Apis.Drive.v3 in asp.net MVC. I want my visitor to upload the files to my google drive, I will set the credentials of my google drive in code. Can anyone help me to get this work?
I tried the quick start sample for upload but it asks for the credentials every time. Or it uses the cached credential.
How can I upload a file without knowing the user about the credential?
According to this documentation, you need to get the access credentials to enable the Google Drive. If you want to programmatically access users data without any manual authorization on their part, then perform Google Apps Domain-Wide Delegation of Authority. To delegate authority this way, domain administrators can use service accounts with OAuth 2.0. You can also check on this link which might help.
I've been reading on Google Drive's API which seems straight-forward enough, but I'd like to use it a bit differently.
Instead of a client-side application, I need to be able to batch copy files in a given directory on a server to a specific Google Drive account which I have control over. To elaborate, I'm implementing a scan-to-email feature in which a user can scan a document on our copier which is then copied to that Google Drive account.
This is done for internal users, so the accounts would be generic and there would be no reasons to change the passwords. Is this possible at all?
I would recommend you go with a service account. Think of a service account as a user, a service account will have its own drive account. You will be able to upload the files to it, and your application wont be required to login as it will have the login built into it. You will not be able to login and see the files for this account via the web interface.
In order for the users to access the files again you have a few options.
You can then set the permissions on the files to allow the different users to access the files via there google drive accounts. Google drive api permissions
you could create your own interface and use files list to list the files that are currently stored on the service account.
Heads up:
You will at some point want to know how much space the service account drive has left. use about.get
Google has a number of client libs that can make doing all of this quite easy. but you haven't said what language you are planning on doing this in.
You could rely on the insert method of the "File" resource within the API. This will allow you to create a Google Drive File with the file type based on the scanned file. Refer to this document for examples and further assistance: https://developers.google.com/drive/v2/reference/files/insert#examples

I'm creating a simple iPhone app. The basic premise is that the app will display some data (That I provide online) on the application. The data changes over time, so the app has to draw the data from online and display it. I don't have a significant programming background so I don't want to use my own server.
Thus, I thought it would be significantly easier to just put the data into some documents on a Google account and then access them programmatically via the Google Drive API. I could then update the data in my Drive account and it would get updated in the application. The key here is that I am ONLY accessing ONE account that I own MYSELF. The users' accounts are not being accessed. Therefore the goal is to never have to log in manually. It should all happen behind the scenes, aka, it should look like a server, not a google doc.
With this in mind, it doesn't make sense to show the Google Accounts sign-in page to my users as the standard OAuth2.0 tutorial shows here:https://developers.google.com/drive/quickstart-ios#step_1_enable_the_drive_api
I should be able to access my own data by somehow hardcoding in my username, password etc. Google agrees here: https://developers.google.com/drive/service-accounts#use_regular_google_accounts_as_application-owned_accounts
The above link mentions a "refresh token" that I'm supposed to save. However, I have no idea how to build and save that token, or even for that matter, where to find it.
I've gone through both the basic tutorial and the Dr. Edit Tutorial for iOS, but they both assume that the application is accessing USER accounts not application-owned accounts.
I'm not asking for someone to write the code for me (though tidbits are nice), but if you can point me to a step-by-step guide or related sample code that would help me get started that would be awesome. I'll even come back and post the code that I use!
EDIT: Since I realized that the Google Drive API wasn't something I could use for what I am trying to do, I eventually found Parse which is an awesome tool that handles all the server backend for me and is free at the basic level.
Google APIs objective-C client library doesn't support service (application-owned) accounts, because they are supposed to be used by a server-side apps, instead of clients -- you shouldn't be distributing your private key as a part of an app.
If you would like to distribute content from a service account, maybe you should write a server leg to do the authentication and pass clients credentials in a secure way for them to talk to the API on the behalf of the service account. Or, use Web publishing to make documents universally accessible without authorization and authentication if privacy is not a concern.
