+aliases:
+- "/operations/components/setup-bindings/supported-bindings/kitex/"
+---
+
+## Overview
+
+The binding for kitex mainly utilizes the generic-call feature in kitex. More information can be found in [kitex generic-call](https://www.cloudwego.io/docs/kitex/tutorials/advanced-feature/generic-call/).
+Currently, kitex only supports Thrift generic calls, and the implementation integrated into [components-contrib](https://github.com/dapr/components-contrib/tree/master/bindings/kitex) adopts binary generic calls.
+
+
+## Component format
+
+To setup an Kitex binding create a component of type `bindings.kitex`. See [this guide]({{< ref "howto-bindings.md#1-create-a-binding" >}}) on how to create and apply a binding configuration.
+
+```yaml
+apiVersion: dapr.io/v1alpha1
+kind: Component
+metadata:
+  name: bindings.kitex
+spec:
+  type: bindings.kitex
+  version: v1
+  metadata: 
+```
+
+## Spec metadata fields
+
+The `InvokeRequest.Metadata` for `bindings.kitex` requires the client to fill in four required items: hostPorts, destService, methodName and version when making a call.
+
+| Field       | Required | Binding support | Details                                                                                                 | Example            |
+|-------------|:--------:|--------|---------------------------------------------------------------------------------------------------------|--------------------|
+| hostPorts   |    Y     | Output | IP address and port information of the kitex server (thrift)                                        | `"127.0.0.1:8888"` |
+| destService |    Y     | Output | Service name of the kitex server (thrift)            | `"echo"`           |
+| methodName  |    Y     | Output | Method name under a specific service name of the kitex server (thrift) | `"echo"`           |
+| version     |    Y     | Output | kitex version                                                                                           | `"0.5.0"`          |
+
+
+## Binding support
+
+This component supports **output binding** with the following operations:
+
+- `get`
+
+## Example 
+
+When using kitex binding, the client needs to pass in the correct Thrift-encoded binary, and the server needs to be a Thrift Server. The [kitex_output_test](https://github.com/dapr/components-contrib/blob/master/bindings/kitex/kitex_output_test.go) can be used as a reference.
+For example, the variable `reqData` needs to be encoded by the Thrift protocol before sending, and the returned data needs to be decoded by the Thrift protocol.
+
+**Request**
+
+```json
+{
+  "operation": "get",
+  "metadata": {
+    "hostPorts": "127.0.0.1:8888",
+    "destService": "echo",
+    "methodName": "echo",
+    "version":"0.5.0"
+  },
+  "data": reqdata
+}
+```
