StateTokenBuilder
Allows scripts to create state tokens that can be used in callback APIs (like OAuth flows).
// Reusable function to generate a callback URL, assuming the script has been
// published as a web app (necessary to obtain the URL programmatically). If the
// script has not been published as a web app, set `var url` in the first line
// to the URL of your script project (which cannot be obtained
// programmatically).
function getCallbackURL(callbackFunction) {
let url = ScriptApp.getService().getUrl(); // Ends in /exec (for a web app)
url = `${
url.slice(0, -4)}usercallback?state=`; // Change /exec to /usercallback
const stateToken = ScriptApp.newStateToken()
.withMethod(callbackFunction)
.withTimeout(120)
.createToken();
return url + stateToken;
}
Detailed documentation
createToken()
Constructs an encrypted string representation of the state token.
const stateToken = ScriptApp.newStateToken().createToken();
Return
String — an encrypted string representing the token
withArgument(name, value)
Adds an argument to the token. This method can be called multiple times.
const stateToken =
ScriptApp.newStateToken().withArgument('myField', 'myValue').createToken();
Parameters
| Name | Type | Description |
name | String | the name of the argument |
value | String | the value of the argument |
Return
StateTokenBuilder — the state token builder, for chaining
withMethod(method)
Sets a callback function. The default is a function named callback().
const stateToken =
ScriptApp.newStateToken().withMethod('myCallback').createToken();
Parameters
| Name | Type | Description |
method | String | The name of the callback function, represented as a string without parentheses or
arguments. You can use functions from included libraries, such as
Library.libFunction1. |
Return
StateTokenBuilder — the state token builder, for chaining
withTimeout(seconds)
Sets the duration (in seconds) for which the token is valid. The defaults is 60 seconds; the
maximum duration is 3600 seconds (1 hour).
const stateToken = ScriptApp.newStateToken().withTimeout(60).createToken();
Parameters
| Name | Type | Description |
seconds | Integer | the duration for which the token is valid; the maximum value is 3600 |
Return
StateTokenBuilder — the state token builder, for chaining
