Authentication Examples

You can use Traffic Policy to add authentication to your endpoints, granting conditional access to traffic trying to reach your services. This page demonstrates a few example rules that do so.

JWT authentication​

This rule adds key-based rate limiting to your endpoints based on your consumers' JWTs. See the Auth0 guide for more information.

See the rate-limit Traffic Policy action docs for more information.

Conditional access using OAuth variables​

This rule grants conditional access to a page using the following ngrok OAuth action result variables:

  1. actions.ngrok.oauth.identity.email.endsWith('ngrok.com')
    1. Checks the email address of the authorized user from the provider. In the example, if the email address's domain is ngrok.com, the user will be granted access to the page.
  • actions.ngrok.oauth.identity.name
    1. Gets the name of the authorized user from the provider. In this example, the name will be displayed in a welcome message or a rejection message depending on if the user is authenticated.
