I’m testing a dynatrace App in React. I’ve a hook that is calling Settings API through TypeScript SDK as you can see on the code snippet:

try {&nbsp; &nbsp; &nbsp; var config = {“schemaIds”:“builtin:alerting.maintenance-window”,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; “scopes”:“environment”}&nbsp; &nbsp; &nbsp; const response = await settingsObjectsClient.getSettingsObjects(config);&nbsp; &nbsp; &nbsp; console.log(response);…&nbsp; &nbsp; } catch (e) {…&nbsp; &nbsp; }But I get the following error in the browser:SyntaxError: Unexpected token ‘O’, “OAuth token”… is not valid JSON  
at JSON.parse (\<anonymous\>)  
at fetchQuery ([http://localhost:3002/ui/main.js:123265:36](http://localhost:3002/ui/main.js:123265:36))And&nbsp; in the console I have this message:Request failed: {“code”:403,“message”:“OAuth token is missing required scope. Use one of: [settings:objects:read]”}I’ve executed the same code in a notebook and there was no problem. So It seams that when I call the same API from React APP, the typescript SDK is not passing the login user authorization token.

Hi&nbsp;[@joseafcampos](https://community.dynatrace.com/user/54362)&nbsp;,

to access the Settings API from your app, you need to add the scope `settings:objects:read` to your app config file. You can find the instructions at&nbsp;[Add permission scopes to use Dynatrace APIs | Dynatrace Developer](https://developer.dynatrace.com/develop/security/add-scopes/)
