# POST /update-connector-registration

`POST /update-connector-registration`

Updates a custom connector that you've previously registered. This operation updates the connector with one of the following:

*   The latest version of the AWS Lambda function that's assigned to the connector
    
*   A new AWS Lambda function that you specify

## Request body

- object
  - `connectorLabel` string, required — The name of the connector. The name is unique for each connector registration in your AWS account.
  - `description` string — A description about the update that you're applying to the connector.
  - `connectorProvisioningConfig` object — Contains information about the configuration of the connector being registered.
    - `lambda` object — Contains information about the configuration of the lambda which is being registered as the connector.
      - `lambdaArn` string, required — Lambda ARN of the connector being registered.
  - `clientToken` string — <p>The <code>clientToken</code> parameter is an idempotency token. It ensures that your <code>UpdateConnectorRegistration</code> 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 <code>clientToken</code> parameter value.</p> <p>If you omit a <code>clientToken</code> value, the Amazon Web Services 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.</p> <p>If you specify input parameters that differ from your first request, an error occurs. If you use a different value for <code>clientToken</code>, Amazon AppFlow considers it a new call to <code>UpdateConnectorRegistration</code>. The token is active for 8 hours.</p>
