## Request Syntax


```
POST /update-connector-registration HTTP/1.1
Content-type: application/json

{
   "clientToken": "string",
   "connectorLabel": "string",
   "connectorProvisioningConfig": { 
      "lambda": { 
         "lambdaArn": "string"
      }
   },
   "description": "string"
}
```

## URI Request Parameters


The request does not use any URI parameters.

## Request Body


The request accepts the following data in JSON format.

 ** [clientToken](#API_UpdateConnectorRegistration_RequestSyntax) **   <a name="appflow-UpdateConnectorRegistration-request-clientToken"></a>
The `clientToken` parameter is an idempotency token. It ensures that your `UpdateConnectorRegistration` request completes only once. You choose the value to pass. For example, if you don't receive a response from your request, you can safely retry the request with the same `clientToken` parameter value.  
If you omit a `clientToken` value, the AWS SDK that you are using inserts a value for you. This way, the SDK can safely retry requests multiple times after a network error. You must provide your own value for other use cases.  
If you specify input parameters that differ from your first request, an error occurs. If you use a different value for `clientToken`, Amazon AppFlow considers it a new call to `UpdateConnectorRegistration`. The token is active for 8 hours.
