Where to enter the token, Using OAuth 2.0 to Access Google APIs
When someone connects with an app using Facebook Login and approves the request for permissions, the app obtains an access token that provides temporary, secure access to Facebook APIs. Access tokens are obtained via a number of methods. The token includes information about when the token will expire and which app generated the token.
Token Based Authentication
Because of privacy checks, the majority of API calls on Facebook need to include an access token. There are different types of access tokens to support different use cases: Access Token Type User Access Token This kind of access token is needed any time the app calls an API to read, modify or write a specific person's Facebook data on their behalf. User access tokens are generally obtained via a login dialog and require a person to permit your app to obtain one.
App Access Token This kind of access token is needed to modify and read app settings.
It can also be used to publish Open Graph actions. It is generated using a pre-agreed secret between the app and Facebook and is then used during calls that change app-wide settings. You obtain an app access where to enter the token via a server-to-server call.

Page Access Token This kind of access token is similar to user access tokens, except that they provide permission to APIs that read, write or modify the data belonging to a Facebook Page. To obtain a page access token you need to start by obtaining a user access token and asking for the Page permission or permissions you need.
Once you have the user access token you then get the page access token via the Graph API. Client Token The client token is an identifier that you can embed into native mobile binaries or desktop apps to identify your app. The client token isn't meant to be a secret identifier because it's embedded in apps.
The client token is used to access app-level APIs, but only a very limited subset. The client token is found in your app's dashboard.
Since the client token is used rarely, we won't talk about it in this document. Instead it's covered in any API documentation that uses the client token.

User Access Tokens Although each platform generates access tokens through different APIs, all platforms follow the basic strategy to get a user token: Short-Term Tokens and Long-Term Tokens User access tokens come in two forms: short-lived tokens and long-lived tokens. Short-lived tokens usually have a lifetime of about an hour or two, while long-lived tokens usually have a lifetime of about 60 days.
You should not depend on these lifetimes remaining the same - the lifetime may change without warning or expire early. See more under handling errors.
Access tokens generated via web login are short-lived tokens, but you can convert them to long-lived tokens by making a server-side API call along with your app secret.
Apps with Standard access to Facebook's Marketing API when using long-lived tokens will receive long-lived tokens that don't have an expiry time.

These tokens are still subject to invalidation for other reasons, but won't expire solely based on time. This is also true of access tokens for System Users in Business Manager. Tokens are Portable One important aspect to understand about access tokens is that they are portable. Once you have an access token you can use it to make calls from a mobile client, a web browser, or from your server to Facebook's servers.
If a token is obtained on a client, you can ship that token down to your server and use it in server-to-server calls. If a token is obtained via a server call, you can also ship that token up to a client and then make the calls from the client.
User Access Tokens
Moving tokens between your client and server must be done securely over HTTPS to ensure the security of people's accounts. Read more about the implications of moving tokens between where to enter the token clients and your server.
Different platforms have different methods to kick off this process and include functionality to manage access tokens on behalf of the developer and the person granting permissions: Android The Facebook SDKs for Android automatically manages user access ambulance options through the class com.
You can learn more about obtaining a user access token by implementing Facebook Login for Android. You can retrieve the user access token by inspecting Session. You can learn more about obtinaing a user access token by implementing Facebook Login for iOS. You can retrieve the user access token by making a call to FB.
If you're reading user data and using it in your app, you should use a user access token instead of an app access token. This is because we assume that native or desktop apps will have the app secret investment platform 10 per hour somewhere and therefore the app access token generated using that secret is not secure. Generating an App Access Token To generate an app access token, you need:.
