# Create an OAuth API script

Create and duplicate an OAuth API script for application registry.

## Before you begin

Generate an SHA-1 thumbprint. For more information, see [Generate a SHA-1 thumbprint](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/generate-thumbprint.md).

Generate a sys\_id when you configure a JWT provider. For more information, see [Configure a JWT provider](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/config-jwt-credential-flow.md).

Role required: admin

## Procedure

1.  Navigate to **All** > **System Definition** > **Script Includes**.

2.  Select and open **EmailCertificateOAuthTemplate**.

3.  Duplicate the script by changing the name in the **Name** field, select **Insert and Stay** from the record menu.

    **Note:** The name must begin with **OAuth** to create an OAuth script.

    The script is copied and created with a different name.

4.  In the copied script, enter the JWT provider sys\_id and SHA-1 thumbprint.

5.  Select **Update**.
