Google Drive API, download and get content files from a account server - flutter

So, i want to get all content in google drive. It only using one account, can we access it everytime in app without need to login it? How?
I also tried to read the documentation but still didn't find out

The only way I can think of right now is save the refresh token of an account on server side and every time an user uses the app give them a new access token.
This way it should suit your needs, one account no login.
Take a look at this for refresh token

Facebook Marketing API App Access Tokens, How do they work?

I want to make an application that runs in the background on a server, and syncs ad information from Facebook to a database on my server periodically (say once per hour).
The application will have no user interaction at all, meaning there is no user to click "I'm okay with Facebook using my info" every time you need to authenticate.
I found this in their docs: https://developers.facebook.com/docs/facebook-login/access-tokens#apptokens
The problem is, it doesn't seem to work. I can generate an access_token just fine. Example here:
$ curl 'https://graph.facebook.com/oauth/access_token?client_id=123456789012345&client_secret=s3cr3tt0k3n12a4zz1345a6fgx5aa3f6&grant_type=client_credentials'
access_token=123456789012345|SomeRandomLettersAndNumbers
However, when I go to use it I just get permission denied errors:
$ curl 'https://graph.facebook.com/v2.6/me/adaccounts?access_token=123456789012345|SomeRandomLettersAndNumbers'
{"error":{"message":"An active access token must be used to query information about the current user.","type":"OAuthException","code":2500,"fbtrace_id":"DQ8ysX2mHCu"}}
Same thing happens when I make the request via their explorer tool found here: https://developers.facebook.com/tools/explorer/
Notes:
I have an app set up.
I am the admin.
I claimed the app on my business account.
I created one ad account.
It is not a Native / Desktop app.
Important one: I can get the info if I use a user token instead of an app token, but this requires me to be on a website, and click through a popup window, which obviously I can't do every hour for my server-side app.
I'm not sure if I have to set the permissions somewhere to allow me to use the access token, or maybe I need to set up a "platform" for my app (none of the available ones seem to fit).
UPDATE:
The answer to this question is to use a system user as documented here: https://developers.facebook.com/ads/blog/post/2016/04/05/system-user-rollout/

Is it possible to view/download the content of the POST done via my facebook application?

I have a scenario, where an authorised user through my application is posting status/uploading pictures via my application by granting required permissions. My application uses graph APIs.
Now, as app administrator if I want to see the content of the post, that the user has uploaded via my application. How do i do it?
I know in graph APIs, I have INSIGHTS api. But, it just gives us the statistics of the posts done via my app or user.
Can i really see the posts?
Assuming as an app admin I only have app access token and app ID. I dont store user access tokens with me.
Actually, I worked on the problem with every possible way. Found out that, even being an APP administrator I will need user access token (stored with me), without which these data shall not be retrieved via APIs.
My need was not to use user access token; But, no Its not possible via APIs as of now.

how the iphone apps keep user logged in

A lot of apps keep user logged in until user manually logs out like facebook, dropbox, etc.
I am wondering how they achieve it? There might be several approaches:
1)Do they store the username and password in a local storage, and automatically log the user in when they open the app again after a long time?
2)Or do they get a long-lived token from the server, and once the user login at very first time, the app gets a token from the server, later on they just use the token? The token will be valid until user manually logout from the app.
For #1, it will only work for native login, if an app supports "log in with facebook or twitter" it won't work.
So I just want to get an idea about how people achieve this feature? Is there any articles talk about it?
Most services like Facebook and Twitter use OAuth to manage the user session.
I use this external framework... https://github.com/nxtbgthng/OAuth2Client
It took me a while of reading and setting up to get right but it works now.
When the user logs in they get an auth token that contains an expiry date. When the expiry date comes the system automatically refreshes the token.
When I send a request to the server I send it via the OAuth framework and it adds the authorisation automatically.

any way to get offline access token w/o verification via credit card or phone?

I want to be able to occasionally programmatically grab some data from the graph API using python that is already accessible to my own FB account. Almost all of what I want is public, so is easy, but a couple Pages, although for large-scale brands, happen to be restricted to logged in users. These are accessible when using an access token (including the example one on the doc page).
I've read that what I need for this is an offline access token so that it won't expire. However, in trying to go through creating one, by first creating an app, it's now asking for credit card or phone verification.
Is there any (allowed) way to get an offline access token without this step? I don't even want to create an app in the first place. I just need a token to pass in with my https://graph.facebook.com/PAGENAME? queries.
thx
There isn't, as far as I know. The verification part is needed for you to access the developer tools and without them you cannot create a new app (the first solution) or use the Graph Explorer to generate an offline_access token.
You could make someone who has a verified account an admin to your pages and then use his access_token, but you would have to keep him as a permanent admin for the token to keep working, so I don't really think you would want that.
Just verify your account. Mine went really smoothly, they simply sent me an sms, no charges for me to pay, I entered the code and that was it

how to get an access code when a facebook user is not involved

I am the owner of a facebook like page. I want to grab the news feed using php and output it on my website. I know that I can do this using a valid access token:
https://graph.facebook.com/my_app_id_here/feed?access_token=My_access_token_here
Problem access tokens expire so I know I need to authenticate periodically to get a new access token.
This is where the problem and confusion arises for me. When I read the authentication guide in the facebook dev docs all it talks about is first authenticating the user to get a authorization code from the user and then authenticating the app using the app secret, app id and auth code fromthe user. But this doesn't apply to my situation - I never have a authorization code form the user - all I'm trying to do is access the feed from a php script running on my server....a user is never involved.
Any ideas anyone?
User has to approve your application only once, and later use they can just access your app and use it without approving
Since you are the owner of the like page, I guess you are also the administrator. What you can do in this case is create an offline access token for this (and only for that) user.
You can then use this access token for your script. No user needs to authenticate anything if you only want to grab the feed of your page with the access token of your administrator.
This token never expires except for changing the user's password or taking away permissions again. Look at this answer to see how to create such an offline access token!
It seems offline_access is no longer available. Now you only get a short-lived access_token and you can ask for a long lived one, which is also renewable. You can't get a permanent one though.
