Each account in Workday Extend is associated with a single region. Each region has a different API gateway and authorization base URL. We display the API gateway for your account on your user profile on the Extend Developer Site.

<b>Note:</b> Extend region information is applicable to Workday Extend Enterprise customers. For personal accounts, use these base URLs:

-   <b>API Gateway:</b> https://api.odp.wcp.workday.com
-   <b>Authorization:</b> https://api.odp.wcp.workday.com/auth


This table displays the API gateway, authorization base URL, and audience URI for each region.

<table><thead><tr><th>Region</th><th>API Gateway</th><th>Authorization Base URL</th><th>SP Entity ID/Audience URI</th></tr></thead><tbody><tr><td>United States</td><td><p>https://api.workday.com</p> <p>https://api.us.wcp.workday.com</p></td><td><p>https://auth.api.workday.com</p> <p>https://api.us.wcp.workday.com/auth</p></td><td><p>https://auth.api.workday.com/sp</p> <p>https://api.us.wcp.workday.com/auth/sp</p></td></tr><tr><td>Germany</td><td>https://api.eu.wcp.workday.com</td><td>https://api.eu.wcp.workday.com/auth</td><td>https://api.eu.wcp.workday.com/auth/sp</td></tr><tr><td>Singapore</td><td>https://api.sg.wcp.workday.com</td><td>https://api.sg.wcp.workday.com/auth</td><td>https://api.sg.wcp.workday.com/auth/sp</td></tr><tr><td>United Kingdom</td><td>https://api.uk.wcp.workday.com</td><td>https://api.uk.wcp.workday.com/auth</td><td>https://api.uk.wcp.workday.com/auth/sp</td></tr></tbody></table><br/>

To see your account’s API Gateway URL, view your [Profile](https://developer.workday.com/profile) on the Developer Site. The API Gateway URL is listed on each account you have access to.

If an app that belongs to an account associated with 1 region calls the API gateway for a different region, you might receive a response of `401: Unauthorized`. You must use the API gateway for the region that the account is associated with.
