Enable the OAuth 2.0 Feature

Before you can begin using OAuth 2.0 in your account, you must enable the feature.

Go to Setup > Company > Enable Features.
Click the SuiteCloud subtab.
In the SuiteScript section, check the following boxes:
- Client SuiteScript. Click I Agree on the SuiteCloud Terms of Service page.
- Server SuiteScript. Click I Agree on the SuiteCloud Terms of Service page.
Note:
You must enable both the Client SuiteScript and Server SuiteScript features to use OAuth 2.0 feature for RESTlets.
In the Manage Authentication section, check the OAuth 2.0 box. Click I Agree on the SuiteCloud Terms of Service page.
Click Save.

Note:
The Manage OAuth 2.0 Authorized Applications link becomes available in the Settings portlet for users with a role that has been assigned Log in Using OAuth 2.0 Access Token permission. Users can only list their own OAuth 2.0 authorized applications through this link. Administrators and users with OAuth 2.0 Authorized Applications Management permission can list all authorized applications in the account on Setup > Users/Roles > OAuth 2.0 Authorized Applications.

After you have enabled the OAuth 2.0 feature:

You must set up OAuth 2.0 roles. See Set Up OAuth 2.0 Roles. See also OAuth 2.0 Permissions.
Administrators and users with the Integration Application permission can configure applications to use OAuth 2.0 to access RESTlets, REST web services, and SuiteAnalytics Connect. See Create Integration Records for Applications to Use OAuth 2.0.
