The client token is an identifier that you can embed into native mobile binaries or desktop apps to identify your app. For example, you could post a status update to a Page rather than on the user's timeline or read Page Insights data. Because of privacy checks, the majority of API calls on Facebook need to include an access token. You can retrieve the user access token by inspecting. Unlike other tokens, Client Access Tokens cannot be used in requests on their own, they must be combined with your App ID. 5rem 1rem;position:relative;background-color: 4a4a4a;color: fff;cursor:pointer;-webkit-transition:all. 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. WELCOME TO THE AVAILABILITY ONLINE BOOKING ENGINE WHY ARE WE DIFFERENT FROM ALL THE REST? Page Access Tokens Page access tokens are used in Graph API calls to manage Facebook Pages. It is generated using a pre-agreed secret between the app and Facebook and is then used during calls that change app-wide settings. button--submit:focus--outlined,[data-processing-success]. button--submit:hover--solid-hover:focus,[data-processing]. Access tokens are obtained via a number of methods. User access tokens are generally obtained via a login dialog and require a person to permit your app to obtain one.

Note that because this request uses your app secret, it must never be made in client-side code or in an app binary that could be decompiled. The token includes information about when the token will expire and which app generated the token. button--submit:hover--outlined,[data-processing]. button--submit--outlined:hover,[data-processing-success]. Instead it's covered in any API documentation that uses the client token. 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 embedded somewhere and therefore the app access token generated using that secret is not secure. 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. Since the client token is used rarely, we won't talk about it in this document. There are different types of access tokens to support different use cases: Access Token Type Description 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. Client Access Tokens A very small number of Graph API endpoints support Client access tokens. button--concrete:visited:focus,. Mobile apps that use Facebook's iOS and Android SDKs get long-lived tokens by default. 2s ease-out,background-image 0s;transition:all. Once granted, you can retrieve the Page access token using a user access token with the required permissions. button--submit--outlined:focus,[data-processing]. Therefore, this API call should only be made using server-side code. 8rem;counter-increment:lists-counter;content:counter blocks-counter ". Limitations Some user data that would normally be visible to an app making a request with a user access token isn't always visible with an app access 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. Tokens are Portable One important aspect to understand about access tokens is that they are portable. Access tokens generated via web login are short-lived tokens, but you can by making a server-side API call along with your app secret. 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. There is another method to make calls to the Graph API that doesn't require using a generated app access token. 3 ;box-shadow:0 0 0 4px rgba 17,17,17,. Generating an App Access Token To generate an app access token, you need:• form--error-all[data-processing-error] input,form. If an endpoint supports another type of token in addition to Client tokens, you should use the other type of token if you are able to do so. 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. Web without JavaScript When building a web app you will need to generate an access token during the steps outlined in that document. 15s ease-in-out,font-size 0s linear;transition:all. 1 2px,transparent 0 ;right:0;opacity:. form--error-all[data-processing-error]. button--submit:hover[data-success-text],[data-processing-success]. button--submit--outlined,[data-processing]. Please use a variable length data type without a specific maximum size to store access tokens. button--submit--outlined:hover,[data-processing]. 1;font-weight:700;color: fff;margin-bottom:1rem;font-size:3. Access Token Length Expect that the length of all access token types will change over time as Facebook makes changes to what is stored in them and how they are encoded. This kind of access token is needed to modify and read app settings. 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 tokens through the class. button--submit:focus--outlined:hover,[data-processing]. button--submit:focus[data-success-text]:before,[data-processing-success]. Like App tokens, Client tokens make Graph API requests on behalf of apps instead of users, but should only be used in cases where a token must be embedded in mobile or web client code instead of stored on a secure, backend server. 3 ;box-shadow:0 0 0 4px rgba 74,194,249,. button--submit:focus[data-success-text],[data-processing-success]. You can expect that they will grow and shrink over time. Page access tokens are unique to each Page, admin, and app. It is important that your app secret is never shared with anyone. button--submit:focus--solid-hover:hover,[data-processing]. button--submit:hover[data-success-text]:before,[data-processing-success]. form--error-all[data-processing-error] select,form.

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. You can retrieve the user access token by making a call to which will include an accessToken property within the response. Apps with to Facebook's Marketing API when using long-lived tokens will receive long-lived tokens that don't have an expiry time. You should not depend on these lifetimes remaining the same - the lifetime may change without warning or expire early.

This can be used to modify the parameters of your app, create and manage test users, or read your app's insights. Moving tokens between your client and server must be done securely over HTTPS to ensure the security of people's accounts. button--submit:focus--outlined:focus,[data-processing]. button--submit:focus,[data-processing-success]. App Access Tokens App access tokens are used to make requests to Facebook APIs on behalf of an app rather than a user. 2;text-align:center;color: fff;font-size:1. The client token is used to access app-level APIs, but only a very limited subset. button--brand:visited--solid-hover. button--submit:focus--outlined:hover,[data-processing-success]. button--submit,[data-processing]. Again, for security, app access token should never be hard-coded into client-side code, doing so would give everyone who loaded your webpage or decompiled your app full access to your app secret, and therefore the ability to modify your app. These tokens are still subject to invalidation for other reasons, but won't expire solely based on time. button--submit:focus--solid-hover,[data-processing]. 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. button--brand:visited--outlined. Once you have the user access token you then get the page access token via the Graph API. Access Tokens An access token is an opaque string that identifies a user, app, or Page and can be used by the app to make graph API calls. It can also be used to publish Open Graph actions. button--submit:focus--outlined,[data-processing]. You obtain an app access token via a server-to-server call. The client token isn't meant to be a secret identifier because it's embedded in apps.。 。
