How to Get Access Token for Sharepoint Rest Api?

If you are a Sharepoint user, it is essential to access the Sharepoint Rest API. This article will help you understand how to get an Access Token for the Sharepoint Rest API.

Understanding Sharepoint Rest API

SharePoint Rest API is a web service that enables you to use the SharePoint platform to create, update, and delete data from your SharePoint databases. It uses the Representational State Transfer (REST) protocol and is built upon the OData (Open Data Protocol) standard. It provides a comprehensive set of operations that can be used to access and manage SharePoint data.

The SharePoint Rest API supports a wide variety of operations such as creating, updating, and deleting lists, managing lists and items, managing users and groups, and managing SharePoint sites. It also provides access to the SharePoint content repository, including documents, images, and other types of files.

The Rest API is the preferred way to interact with SharePoint data, as it provides a more consistent, secure, and efficient way to interact with the data.

Steps to Get Access Token for Sharepoint Rest API

Step 1: Creating an App Registration

The first step in getting an Access Token for SharePoint Rest API is to create an App Registration. This is done by signing in to your Azure account, navigating to the App Registrations page, and creating a new app. Enter the app name, select the type of account, and select the application type.

Step 2: Get the Client ID and Client Secret

Once the App registration is created, you will need to get the Client ID and Client Secret. These will be used to authenticate with the SharePoint Rest API. To get the Client ID and Client Secret, navigate to the App Registrations page and select the app you created. You will find the Client ID and Client Secret under the “Settings” tab.

Step 3: Get the Access Token

Now that you have the Client ID and Client Secret, you can use them to get the Access Token. To do this, you need to make a POST request to the SharePoint Rest API. The request will include the Client ID, Client Secret, and the resource you want to access. The response will include the Access Token, which you can use to access the SharePoint Rest API.

Step 4: Using the Access Token

Once you have the Access Token, you can use it to access the SharePoint Rest API. You will need to include the Access Token in the Authorization header of the request. This will allow you to access the resources you need.

Step 5: Refreshing the Access Token

The Access Token will expire after a certain period of time. When this happens, you will need to get a new Access Token. To do this, you will need to make a request to the SharePoint Rest API and include the Client ID, Client Secret, and the Refresh Token. The response will include a new Access Token, which you can use to access the SharePoint Rest API.

Conclusion

By following the steps outlined in this article, you can easily get an Access Token for the SharePoint Rest API. Once you have the Access Token, you can use it to access the SharePoint Rest API and access the resources you need.

Frequently Asked Questions

What is a Sharepoint Access Token?

A Sharepoint access token is a credential used to authenticate a user or an application to access resources stored in a Sharepoint instance. It is generated through an authorization flow and provides access to certain Sharepoint data and functionality. The access token acts as a bearer token, which allows the user or application to access specific resources without further authentication.

Sharepoint access tokens are issued by the authorization server and can be used by the user or application to access specific resources from the Sharepoint instance without further authentication. The access token is a key to unlocking the resources stored in the Sharepoint instance for the particular user or application.

How to Get Access Token for Sharepoint Rest Api?

In order to get an access token for Sharepoint Rest API, you will need to use a client library such as the MSAL (Microsoft Authentication Library) or ADAL (Azure Active Directory Authentication Library). Both of these libraries will allow you to authenticate with a Sharepoint instance and retrieve an access token which can then be used to access the data stored in the Sharepoint instance.

To get an access token you will need to create a new application registration in Azure Active Directory and configure it to use a Sharepoint instance as the authorization server. Once this is done you will be able to use either of the two client libraries to authenticate with the Sharepoint instance and obtain an access token. This token can then be used to access the resources stored in the Sharepoint instance for the particular user or application.

What is the Difference Between Access Token and Refresh Token?

An access token is a credential used to authenticate a user or application to access resources stored in a Sharepoint instance. It is generated through an authorization flow and provides access to certain Sharepoint data and functionality. An access token is a bearer token and allows the user or application to access specific resources without further authentication.

A refresh token is a credential used to obtain a new access token. It is generated when the user or application first authenticates with the Sharepoint instance, and it can be used to obtain a new access token when the current access token expires. Refresh tokens are long-lived credentials and can be used multiple times to obtain new access tokens.

What is the Difference Between the MSAL and ADAL Libraries?

The MSAL (Microsoft Authentication Library) and ADAL (Azure Active Directory Authentication Library) are two client libraries used to authenticate with a Sharepoint instance and retrieve an access token. Both of these libraries provide the same functionality, but there are some key differences between them.

The MSAL library provides a more modern authentication experience and supports modern authentication protocols such as OpenID Connect, OAuth2, and SAML. It also supports automatic token refreshing and silent authentication, which makes it more suitable for applications. On the other hand, the ADAL library is a legacy library and does not support modern authentication protocols. It is more suitable for applications that require manual authentication.

What is the Difference Between a Bearer Token and an Access Token?

A bearer token is a type of access token that is used to authenticate a user or application to access resources stored in a Sharepoint instance. It is generated through an authorization flow and provides access to certain Sharepoint data and functionality. The bearer token acts as a key to unlocking the resources stored in the Sharepoint instance for the particular user or application.

On the other hand, an access token is a credential used to authenticate a user or application to access resources stored in a Sharepoint instance. It is generated through an authorization flow and provides access to certain Sharepoint data and functionality. The access token is a key to unlocking the resources stored in the Sharepoint instance for the particular user or application.

What is the Difference Between a Client Library and an Authorization Server?

A client library is a software library used to authenticate with a Sharepoint instance and retrieve an access token. Examples of client libraries include MSAL (Microsoft Authentication Library) and ADAL (Azure Active Directory Authentication Library). These libraries allow users and applications to authenticate with the Sharepoint instance and obtain an access token which can then be used to access the data stored in the Sharepoint instance.

An authorization server is the entity responsible for issuing access tokens to users and applications. In the context of Sharepoint, the authorization server is usually the Sharepoint instance itself. The authorization server verifies the user or application’s credentials and then issues an access token which can be used to access the data stored in the Sharepoint instance.

If you want to use the Sharepoint REST API, getting the access token is essential. With the right steps, you can get the access token and start using the API. Make sure to use the right authentication methods, use the right URL’s, and provide the right parameters to get the access token. With the right knowledge, you can easily get the access token and start using the Sharepoint REST API.
