Detailed documentation

deleteTrigger(trigger)

Removes the given trigger so it no longer runs.

// Deletes all triggers in the current project.
const triggers = ScriptApp.getProjectTriggers();
for (let i = 0; i < triggers.length; i++) {
  ScriptApp.deleteTrigger(triggers[i]);
}

Parameters

NameTypeDescription
triggerTriggerThe trigger to delete.

Authorization

Scripts that use this method require authorization with one or more of the following scopes:

  • https://www.googleapis.com/auth/script.scriptapp

getAuthorizationInfo(authMode)

Gets an object used to determine whether the user needs to authorize this script to use one or more services, and to provide the URL for an authorization dialog. If the script is published as an add-on that uses installable triggers, this information can be used to control access to sections of code for which the user lacks the necessary authorization. Alternately, the add-on can ask the user to open the URL for the authorization dialog to resolve the problem.

var authInfo = ScriptApp.getAuthorizationInfo(ScriptApp.AuthMode.FULL);
status = authInfo.getAuthorizationStatus();
url = authInfo.getAuthorizationUrl();

Parameters

NameTypeDescription
authModeAuthModethe authorization mode for which authorization information is requested; in almost all cases, the value for authMode should be ScriptApp.getAuthorizationInfo(ScriptApp.AuthMode.FULL), since no other authorization mode requires that users grant authorization

Return

AuthorizationInfo — an object that can provide information about the user's authorization status


getIdentityToken()

Gets an OpenID Connect identity token for the effective user, if the openid scope has been granted. This scope is not included by default, and you must add it as an explicit scope in the manifest file to request it. Include the scopes https://www.googleapis.com/auth/userinfo.email or https://www.googleapis.com/auth/userinfo.profile to return additional user information in the token.

The returned ID token is an encoded JSON Web Token (JWT), and it must be decoded to extract information from it. The following examples shows how to decode the token and extract the effective user's Google profile ID.

const idToken = ScriptApp.getIdentityToken();
const body = idToken.split('.')[1];
const decoded = Utilities
                    .newBlob(
                        Utilities.base64Decode(body),
                        )
                    .getDataAsString();
const payload = JSON.parse(decoded);

Logger.log(`Profile ID: ${payload.sub}`);
See the OpenID Connect documentation for the full list of fields (claims) returned.

Return

String — The identity token if available; otherwise null.


getInstallationSource()

Returns an enum value that indicates how the script came to be installed as an add-on for the current user (for example, whether the user installed it personally through the Chrome Web Store, or whether a domain administrator installed it for all users).

Return

InstallationSource — The source of installation.


getOAuthToken()

Gets the OAuth 2.0 access token for the effective user. If the script's OAuth scopes are sufficient to authorize another Google API that normally requires its own OAuth flow (like Google Picker), scripts can bypass the second authorization prompt by passing this token instead. The token expires after a time (a few minutes at minimum); scripts should handle authorization failures and call this method to obtain a fresh token when needed.

The token returned by this method only includes scopes that the script currently needs. Scopes that were previously authorized but are no longer used by the script are not included in the returned token. If additional OAuth scopes are needed beyond what the script itself requires, they can be specified in the script's manifest file.

Return

String — A string representation of the OAuth 2.0 token.


getProjectTriggers()

Gets all installable triggers associated with the current project and current user.

Logger.log(
    `Current project has ${ScriptApp.getProjectTriggers().length} triggers.`,
);

Return

Trigger[] — An array of the current user's triggers associated with this project.

Authorization

Scripts that use this method require authorization with one or more of the following scopes:

  • https://www.googleapis.com/auth/script.scriptapp

getScriptId()

Gets the script project's unique ID. This is the preferred method to get the unique identifier for the script project as opposed to getProjectKey(). This ID can be used in all places where project key was previously provided.

Return

String — The script project's ID.


getService()

Gets an object used to control publishing the script as a web app.

// Get the URL of the published web app.
const url = ScriptApp.getService().getUrl();

Return

Service — An object used to observe and control publishing the script as a web app.


getUserTriggers(document)

Gets all installable triggers owned by this user in the given document, for this script or add-on only. This method cannot be used to see the triggers attached to other scripts.

const doc = DocumentApp.getActiveDocument();
const triggers = ScriptApp.getUserTriggers(doc);
// Log the handler function for the first trigger in the array.
Logger.log(triggers[0].getHandlerFunction());

Parameters

NameTypeDescription
documentDocumentA Google Docs file that may contain installable triggers.

Return

Trigger[] — An array of triggers owned by this user in the given document.

Authorization

Scripts that use this method require authorization with one or more of the following scopes:

  • https://www.googleapis.com/auth/script.scriptapp

getUserTriggers(form)

Gets all installable triggers owned by this user in the given form, for this script or add-on only. This method cannot be used to see the triggers attached to other scripts.

const form = FormApp.getActiveForm();
const triggers = ScriptApp.getUserTriggers(form);
// Log the trigger source for the first trigger in the array.
Logger.log(triggers[0].getTriggerSource());

Parameters

NameTypeDescription
formFormA Google Forms file that may contain installable triggers.

Return

Trigger[] — An array of triggers owned by this user in the given form.

Authorization

Scripts that use this method require authorization with one or more of the following scopes:

  • https://www.googleapis.com/auth/script.scriptapp

getUserTriggers(spreadsheet)

Gets all installable triggers owned by this user in the given spreadsheet, for this script or add-on only. This method cannot be used to see the triggers attached to other scripts.

const ss = SpreadsheetApp.getActiveSpreadsheet();
const triggers = ScriptApp.getUserTriggers(ss);
// Log the event type for the first trigger in the array.
Logger.log(triggers[0].getEventType());

Parameters

NameTypeDescription
spreadsheetSpreadsheetA Google Sheets file that may contain installable triggers.

Return

Trigger[] — An array of triggers owned by this user in the given spreadsheet.

Authorization

Scripts that use this method require authorization with one or more of the following scopes:

  • https://www.googleapis.com/auth/script.scriptapp

invalidateAuth()

Invalidates the authorization the effective user has to execute the current script. Used to invalidate any permissions for the current script. This is especially useful for functions tagged as one-shot authorization. Since one-shot authorization functions can only be called the first run after the script has acquired authorization, if you wish to perform an action afterwards, you must revoke any authorization the script had, so the user can see the authorization dialog again.

ScriptApp.invalidateAuth();

Throws

Error — when invalidation fails


newStateToken()

Creates a builder for a state token that can be used in a callback API (like an OAuth flow).

// Generate a callback URL, given the name of a callback function. The script
// does not need to be published as a web app; the /usercallback URL suffix
// replaces /edit in any script's URL.
function getCallbackURL(callbackFunction) {
  // IMPORTANT: Replace string below with the URL from your script, minus the
  // /edit at the end.
  const scriptUrl =
      'https://script.google.com/macros/d/1234567890abcdefghijklmonpqrstuvwxyz';
  const urlSuffix = '/usercallback?state=';
  const stateToken = ScriptApp.newStateToken()
                         .withMethod(callbackFunction)
                         .withTimeout(120)
                         .createToken();
  return scriptUrl + urlSuffix + stateToken;
}

In most OAuth2 flows, the state token is passed to the authorization endpoint directly (not as part of the callback URL), and the authorization endpoint then passes it as part of the callback URL.

For example:

  • The script redirects the user to OAuth2 authorize URL: https://accounts.google.com/o/oauth2/auth?state=token_generated_with_this_method&callback_uri=https://script.google.com/macros/d/1234567890abcdefghijklmonpqrstuvwxyz/usercallback&other_oauth2_parameters
  • The user clicks authorize, and the OAuth2 authorization page redirects the user back to https://script.google.com/macros/d/1234567890abcdefghijklmonpqrstuvwxyz/usercallback?state=token_generated_with_this_method&other_params_that_include_tokens_or_grants
  • The above redirect (back to http://script.google.com/...), causes the browser request to /usercallback, which invokes the method specified by StateTokenBuilder.withMethod(method).

Return

StateTokenBuilder — An object used to continue the state-token-building process.


newTrigger(functionName)

Begins the process of creating an installable trigger that, when fired, calls a given function.

// Creates an edit trigger for a spreadsheet identified by ID.
ScriptApp.newTrigger('myFunction')
    .forSpreadsheet('1234567890abcdefghijklmnopqrstuvwxyz_a1b2c3')
    .onEdit()
    .create();

Parameters

NameTypeDescription
functionNameStringThe function to call when the trigger fires. You can use functions from included libraries, such as Library.libFunction1.

Return

TriggerBuilder — An object used to continue the trigger-building process.
