Authentication

    Community connectors support the following authentication methods:

    • OAuth 2.0
    • Path/Username/Password
    • Path/Key
    • Username/Password
    • Username/Token
    • Key
    • None

    Depending on which method you are using, you must provide additional functions in your connector.

    The following table indicates which functions you must define depending on the authentication type of your connector.

    OAUTH2 PATH_USER_PASS

    getAuthType()

    This function should return the authentication type for the connector.

    isAuthValid()

    This function is called to determine if the authentication for the third-party service is valid. If authentication is valid then it is expected that calls to getData() and getSchema() will not fail due to unauthorized access. If the auth is not valid then the user may receive a notification to start the authorization flow.

    OAUTH2

    Add and setup OAuth2 for Apps Script Library

    Follow the setup instructions for the OAuth2 for Apps Script library to add it to your connector project. Then follow the first step in the usage guide to create an OAuth2 service in your connector project. Your OAuth2 service can have any valid function name but make sure to use the same name while referring to the OAuth2 service in your code.

    For example, an OAuth2 service named exampleService :

    data-studio/auth.gs
     /** 
 * Returns the configured OAuth Service. 
 * @return {Service} The OAuth Service 
 */ 
 function 
  
 getOAuthService 
 () 
  
 { 
  
 return 
  
 OAuth2 
 . 
 createService 
 ( 
 'exampleService' 
 ) 
  
 . 
 setAuthorizationBaseUrl 
 ( 
 '...' 
 ) 
  
 . 
 setTokenUrl 
 ( 
 '...' 
 ) 
  
 . 
 setClientId 
 ( 
 '...' 
 ) 
  
 . 
 setClientSecret 
 ( 
 '...' 
 ) 
  
 . 
 setPropertyStore 
 ( 
 PropertiesService 
 . 
 getUserProperties 
 ()) 
  
 . 
 setCallbackFunction 
 ( 
 'authCallback' 
 ) 
  
 . 
 setScope 
 ( 
 '...' 
 ); 
 };

    authCallback()

    This function is called to complete the OAuth 2.0 flow. The callback response from the third-party auth service is provided as an argument and should be handled by this function.

    Example of handling the OAuth 2.0 callback using the OAuth2 for Apps Script library:

    data-studio/auth.gs
     /** 
 * The OAuth callback. 
 * @param {object} request The request data received from the OAuth flow. 
 * @return {HtmlOutput} The HTML output to show to the user. 
 */ 
 function 
  
 authCallback 
 ( 
 request 
 ) 
  
 { 
  
 var 
  
 authorized 
  
 = 
  
 getOAuthService 
 (). 
 handleCallback 
 ( 
 request 
 ); 
  
 if 
  
 ( 
 authorized 
 ) 
  
 { 
  
 return 
  
 HtmlService 
 . 
 createHtmlOutput 
 ( 
 'Success! You can close this tab.' 
 ); 
  
 } 
  
 else 
  
 { 
  
 return 
  
 HtmlService 
 . 
 createHtmlOutput 
 ( 
 'Denied. You can close this tab' 
 ); 
  
 }; 
 };

    get3PAuthorizationUrls()

    This function is called to get the URL that is required to initiate the auth flow for the third-party service. If isAuthValid returns false then the URL returned will be displayed to the user as a button or link so that they can authorize access to the third-party service. See the reference for get3PAuthorizationUrls() .

    Example of returning the authorization Url using the OAuth2 for Apps Script library:

    data-studio/auth.gs
     /** 
 * Gets the 3P authorization URL. 
 * @return {string} The authorization URL. 
 * @see https://developers.google.com/apps-script/reference/script/authorization-info 
 */ 
 function 
  
 get3PAuthorizationUrls 
 () 
  
 { 
  
 return 
  
 getOAuthService 
 (). 
 getAuthorizationUrl 
 (); 
 }

    USER_PASS , USER_TOKEN , KEY , PATH_USER_PASS , and PATH_KEY

    The following is only needed for the USER_PASS , USER_TOKEN , KEY , PATH_USER_PASS , and PATH_KEY authentication flows.

    setCredentials()

    setCredentials is called after the user enters either their credential information on the community connector configuration page. You should use the Properties Service to save the credentials on a per-user basis using UserProperties .

    PATH_USER_PASS

      /** 
 * Sets the credentials. 
 * @param {Request} request The set credentials request. 
 * @return {object} An object with an errorCode.
