# Use JWTs to verify requests to API gateways on Kubernetes
This topic describes how to use JSON web tokens (JWT) to verify requests to API gateways deployed to Kubernetes-orchestrated containers. If your API gateway is deployed to virtual machines, refer to [Use JWTs to verify requests to API gateways on VMs](/consu/docs/connect/gateways/api-gateway/secure-traffic/verify-jwts-vms).

<EnterpriseAlert> This feature is available in Consul Enterprise. </EnterpriseAlert>
## Overview
You can configure API gateways to use JWTs to verify incoming requests so that you can stop unverified traffic at the gateway. You can configure JWT verification at different levels:
- Listener defaults: Define basic defaults that apply to all routes attached to a listener.
- HTTP route-specific settings: You can define JWT authentication settings for specific HTTP routes. Route-specific JWT settings override default listener configurations.
- HTTP route-specific settings: You can define JWT authentication settings for specific HTTP routes. Route-specific JWT settings override default listener configurations.
- Listener overrides: Define override settings that take precedence over default and route-specific configurations. This enables you to set enforceable policies for listeners.
Complete the following steps to use JWTs to verify requests:
1. Define a policy that specifies default and override settings for API gateway listeners and attach it to the gateway.
1. Define a policy that specifies default and override settings for API gateway listeners and attach it to the gateway.
1. Define an HTTP route auth filter that specifies route-specific JWT verification settings.
1. Attach the auth filter to the HTTP route values file.
1. Apply the configurations.

## Define override and default settings
Create a `GatewayPolicy` values file and configure the following fields to define default and override settings for JWT verification. Refer to [`GatewayPolicy` configuration reference](/consul/docs/connect/gateways/api-gateway/configuration/gatewaypolicy) for details.
Create a `GatewayPolicy` values file and configure the following fields to define default and override settings for JWT verification. Refer to [`GatewayPolicy` configuration reference](/consul/docs/connect/gateways/api-gateway/configuration/gatewaypolicy) for details.
- `kind`: Must be set to `GatewayPolicy`
- `metadata.name`: Specifies a name for the policy.
- `spec.targetRef.name`: Specifies the name of the API gateway to attach the policy to.

- `spec.targetRef.kind`: Specifies the kind of resource to attach to the policy to. Must be set to `Gateway`.
- `spec.targetRef.group`: Specifies the resource group. Unless you have created a custom group, this should be set to `gateway.networking.kuberenetes.io`.
- `spec.targetRef.sectionName`: Specifies a part of the gateway that the policy applies to.
- `spec.targetRef.override.jwt.providers`: Specifies a list of providers and claims used to verify requests to the gateway. The override settings take precedence over the default and route-specific JWT verification settings.
- `spec.targetRef.default.jwt.providers`: Specifies a list of default providers and claims used to verify requests to the gateway.
