RegisterConnector - AmazonAppFlow


Registers a new custom connector with your AWS account. Before you can register the connector, you must deploy the associated AWS lambda function in your account.

Request Syntax

POST /register-connector HTTP/1.1 Content-type: application/json { "clientToken": "string", "connectorLabel": "string", "connectorProvisioningConfig": { "lambda": { "lambdaArn": "string" } }, "connectorProvisioningType": "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.


The clientToken parameter is an idempotency token. It ensures that your RegisterConnector 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 RegisterConnector. The token is active for 8 hours.
