    </Frame>
  </Step>
</Steps>

Use the ABBYY Vantage server address for your region:

<CodeGroup>
  ```text US theme={null}
  https://vantage-us.abbyy.com
  ```

  ```text EU theme={null}
  https://vantage-eu.abbyy.com
  ```

  ```text AU theme={null}
  https://vantage-au.abbyy.com
  ```
</CodeGroup>

  </Step>
</Steps>

## Configure the Authentication Profile

The connector authenticates to ABBYY Vantage with an OAuth 2.0 client. Create a Public API Client in ABBYY Vantage, and then enter its credentials in the Pega authentication profile.

<Steps>
  <Step title="Create a Public API Client in ABBYY Vantage">
    In ABBYY Vantage, create a Public API Client and save its client ID and client secret. In the **OAuth 2.0 Flows Settings**, enable **Allow client credentials flow**, and assign the roles the connector needs with **Manage Roles**, such as **Skill User**. For more information, see [Configure a Public API client](/vantage/documentation/tenant-admin/tenant-management/configure-client).
  </Step>

  <Step title="Enter the client credentials in Pega">
    Open **Records > Security > Authentication Profile** and select the **AbbyyVantage** profile. Enter the client ID and client secret in the **Client identifier** and **Client secret** fields.
  </Step>

  <Step title="Save the authentication profile">
    Save the changes to the authentication profile.
  </Step>
</Steps>

### Set the access token endpoint

Specify the access token endpoint for your region:

<CodeGroup>
  ```text US theme={null}
  https://vantage-us.abbyy.com/auth2/connect/token
  ```

  ```text EU theme={null}
  https://vantage-eu.abbyy.com/auth2/connect/token
  ```

  ```text AU theme={null}
  https://vantage-au.abbyy.com/auth2/connect/token
  ```
</CodeGroup>

If the ABBYY Vantage user is registered in several tenants, include the tenant identifier in the endpoint:

<CodeGroup>
  ```text US theme={null}
  https://vantage-us.abbyy.com/auth2/<tenant-identifier>/connect/token
  ```

  ```text EU theme={null}
  https://vantage-eu.abbyy.com/auth2/<tenant-identifier>/connect/token
  ```

  ```text AU theme={null}
  https://vantage-au.abbyy.com/auth2/<tenant-identifier>/connect/token
  ```
</CodeGroup>

To find the tenant identifier, log in to the ABBYY Vantage tenant as a tenant administrator, open **Configuration > General**, and copy the tenant identifier.
