Set up OAuth provider with JWT Bearer grant type

JSON Web Tokens (JWTs) enable the capability to configure server-to-server API interactions between ServiceNow and external API providers without requiring any user intervention. This support enables IntegrationHub or other automated tasks using JWTs to configure API and Service integrations with different providers.

About this task

The following tasks show how ServiceNow can be set up to use JWTs for OAuth 2.0 client authentication and authorization grants. ServiceNow is the OAuth client, and you can configure an OAuth provider, such as Box or Docusign.

Procedure

  1. Upload Java Key Store certificate
    Attach a JKS certificate to your instance to use to enable the JWT client authentication.
  2. Configure a JWT signing key
    Create a JWT signing key to assign to your Java KeyStore (JKS) certificate.
  3. Create a JWT provider with a JWT signing key
    Add a JWT provider to your ServiceNow instance.
  4. Connect to a third-party OAuth provider
    Create a third-party OAuth provider with a JWT Bearer as the default grant type in the ServiceNow Application Registry.
  5. Specify an OAuth profile
    Open the OAuth entity profile of the OAuth provider and assign a JWT provider.

    Signing Algorithm The algorithm to use to sign with the JWT key. RSA 256 is the only algorithm available.
    Signing Key Password The password associated with the signing key.
    Active Designate that the JWT key alias is actively referenced from a JWT provider.
