client_id is used to identify your client application. After you register a client application, you'll find the client_id in the list of client applications in the workspace settings panel.client_secret is generated in the client applications section of awork. It is located next to the client_id on the workspace settings page. The secret will be used to authenticate your client application when you request a token.offline_access: continued access, issues a refresh token.Access Token is used to authenticate yourself within the API resources. It needs to be included in every request to the API. Each user has to use their own unique Access Token, since such tokens are only valid with the associated user. Also, Access Tokens are valid for one workspace only. If the client application wants to access multiple workspaces, it needs to request separate tokens. The token is usually valid for only a few days.Refresh Token is used to get a new Access Tokenonce that one has expired. A Refresh Token only expires when the user manually revokes access for the client application.Authorization Code is a transitory code used to retrieve an Access Token. It should not be stored in the client application.Access Token and exchange a Refresh Token for a new Access Token:Authorization Endpoint: /accounts/authorize may be used to initially retrieve an Authorization Code.Token Endpoint: /accounts/token may be used to retrieve an Access Token from either an Authorization Code or a Refresh Token.application/x-www-form-urlencoded format. The client directs the user to the constructed URI using a browser window. The user is prompted to log in, enter her or his username and password, and grant the requested permissions to the client application. If the user is part of several workspaces in awork, the user needs to select the workspace before authorizing the application.client_id: The client Id of the client application - Required.redirect_uri: The user will be redirected to a custom URI after the access was granted.
