OAuth
This section provides a complete list of the OAuth properties you can configure in the connection string for this provider.
| Property | Description |
| InitiateOAuth | Specifies the process for obtaining or refreshing the OAuth access token, which maintains user access while an authenticated, authorized user is working. |
| OAuthClientId | Specifies the client Id that was assigned the custom OAuth application was created. (Also known as the consumer key.) This ID registers the custom application with the OAuth authorization server. |
| OAuthClientSecret | Specifies the client secret that was assigned when the custom OAuth application was created. (Also known as the consumer secret ). This secret registers the custom application with the OAuth authorization server. |
| OAuthAccessToken | A token received after authentication to the OAuth network, granting the user access. The access token is used in place of the user's login ID and password, which stay on the server. |
| OAuthSettingsLocation | Specifies the location of the settings file where OAuth values are saved. Storing OAuth settings in a central location avoids the need for users to enter OAuth connection properties manually each time they log in. It also enables credentials to be shared across connections or processes. |
| CallbackURL | The URL users return to after authenticating to Microsoft Project via OAuth. |
| Scope | The scopes used for the OAuth or AzureAD flow. Should be separated with a whitespace. For the OAuth flow, it defaults to the following: ProjectAdmin.Manage Projects.Write ProjectResources.Write ProjectReporting.Read. A list of the available scopes and their aliases can be found here: https://docs.microsoft.com/en-us/sharepoint/dev/sp-add-ins/authorization-code-oauth-flow-for-sharepoint-add-ins?redirectedfrom=MSDN#permission-scope-aliases-and-the-oauthauthorizeaspx-page. For the AzureAD flow, it defaults to the following: offline_access https://MyOrganization.sharepoint.com/.default . A list of the available Azure scopes can be found under API Permissions > SharePoint when customizing any app in the Azure Portal > App Registrations page. |
| State | Optional value for representing extra OAuth state information. |
| OAuthVerifier | Specifies a verifier code returned from the OAuthAuthorizationURL . Used when authenticating to OAuth on a headless server, where a browser can't be launched. Requires both OAuthSettingsLocation and OAuthVerifier to be set. |
| OAuthRefreshToken | Gets and refreshes the currently-active OAuth Access Token. |
| OAuthExpiresIn | Specifies the duration in seconds, of an OAuth Access Token's lifetime. The token can be reissued to keep access alive as long as the user keeps working. |
| OAuthTokenTimestamp | Displays a Unix epoch timestamp in milliseconds that shows how long ago the current Access Token was created. |
