--- layout: docs page_title: Consul API Gateway Configuration description: >- Consul API Gateway Configuration --- # Configuration This topic provides an overview of the configuration items that enable Consul API Gateway to facilitate ingress into your Consul service mesh. - [Gateway](/docs/api-gateway/configuration/gateway): Defines the main infrastructure resource that links API gateway components. It specifies the name of the `GatewayClass` and one or more listeners (see [Listeners](/docs/api-gateway/configuration/gateway#listeners)), which specify the logical endpoints bound to the gateway's addresses. - [GatewayClassConfig](/docs/api-gateway/configuration/gatewayclassconfig): Describes additional Consul API Gateway-related configuration parameters for the GatewayClass resource. - [GatewayClass](/docs/api-gateway/configuration/gatewayclass): Defines a class of gateway resources that you can use as a template for creating gateways. - [Routes](/docs/api-gateway/configuration/routes): Specifies the path from the gateway to the backend service(s)client to the listener. A basic Gateway object can simply use the default [`gatewayClassName`](/docs/api-gateway/configuration/gateway#gatewayClassName) `consul-api-gateway`. For additional configruation options follow the following steps. 1. Define a [GatewayClassConfig](/docs/api-gateway/configuration/gatewayclassconfig) containing your desired configurations. 1. Define a [GatewayClass](/docs/api-gateway/configuration/gatewayclass) with [`parametersRef.name`](/docs/api-gateway/configuration/gatewayclass#parametersRef-name) set to the name of the newly defined [GatewayClassConfig](/docs/api-gateway/configuration/gatewayclassconfig) 1. Define a [Gateway](/docs/api-gateway/configuration/gateway) with [`gatewayClassName`](/docs/api-gateway/configuration/gateway#gatewayClassName) set to the name of the newly defined [GatewayClass](/docs/api-gateway/configuration/gatewayclass)
