This string includes the properties you may need to connect through a proxy server with OAuth 2.0 refresh token grant authentication.

jdbc:datadirect:sharepoint:ServiceURL=serviceurl;ProxyHost=proxy_host;
ProxyPassword=proxy_password;ProxyPort=proxy_port;ProxyUser=proxy_user;
ClientID=client_id;ClientSecret=client_secret;TokenURI=token_uri;
RefreshToken=refresh_token;[property=value[;...]];

where:

serviceurl
specifies the URL of a SharePoint site (or "site collection"), for example, https://mycorp.sharepoint.com/sites/marketing/global. The URL must include the base URL (https://mycorp.sharepoint.com/), as well as the path to the site (marketing/global). The driver uses the base URL to infer an OData endpoint, and the site path is used to locate the site that will be accessed.
proxy_host
specifies the proxy server to use for the first connection.
proxy_password
specifies the password needed to connect to a proxy server for the first connection.
proxy_port
specifies the port number where the proxy server is listening for requests for the first connection. The default is 0.
proxy_user
specifies the user name needed to connect to a proxy server for the first connection.
client_id
specifies the client ID key for your application.
client_secret
specifies the client secret for your application.

Important: The client secret is a confidential value used to authenticate the application to the server. To prevent unauthorized access, this value must be securely maintained.

token_uri
specifies the endpoint used to exchange authentication credentials for access tokens.
refresh_token
specifies the refresh token used to either request a new access token or renew an expired access token.

Important: The refresh token is a confidential value used to authenticate to the server. To prevent unauthorized access, this value must be securely maintained.

property=value
specifies connection property settings. Multiple properties are separated by a semi-colon.

The following example connection string includes the properties required for using a proxy server with OAuth 2.0 refresh token grant authentication.
