> Add Organization support to a Cross App Access (XAA) IdP to associate access tokens with `org_id`.

# Add Organization Support

<Warning>
  Cross App Access (XAA) for the Resource App is in **Early Access**. Enterprise, B2B Pro, and B2B Essential customers can use it as a feature of Enterprise Connections. You can also try it during the trial period on Free tenants. By using this feature, you agree to the applicable Free Trial terms in Okta's [Master Subscription Agreement](https://www.okta.com/legal/?_gl=1*51wq70*_gcl_au*NzczNzM1NjYyLjE3ODE3NzY0MDI.*_ga*MTE3ODU0MTY1Ny4xNzgxNzc2NDAy*_ga_QKMSDV5369*czE3ODQ1NTM3ODckbzgyJGcxJHQxNzg0NTU0NzIxJGo1OCRsMCRoMA..).
</Warning>

## Configure an Organization

If you want an enterprise customer to use Organizations, [create an Organization](/docs/manage-users/organizations/configure-organizations/create-organizations) and [enable the Enterprise connection you configured for XAA](/docs/manage-users/organizations/configure-organizations/enable-connections) for that Organization. This automatically associates access tokens generated using XAA, in the scope of this connection, to the corresponding `org_id` if the target user is a member of the Organization.

You can also configure the Requesting App’s [Organization behavior](/docs/manage-users/organizations/configure-organizations/define-organization-behavior) to set whether it is required or allowed to use Organizations. We recommend that you start testing with **Both**, which allows users to log in as an Organization member or sign up with a personal account.

If the Requesting App is a third-party application, [Enable Third-Party Application Access for an Organization](/docs/manage-users/organizations/configure-organizations/enable-third-party-application-access).
