   **Required** if `type` is `AWS`, `AWS_PROXY`, `HTTP` or `HTTP_PROXY`.
   Not all methods are compatible with all `AWS` integrations.
   e.g. Lambda function [can only be invoked](https://github.com/awslabs/aws-apigateway-importer/issues/9#issuecomment-129651005) via `POST`.
-* `type` - (Required) The integration input's [type](https://docs.aws.amazon.com/apigateway/api-reference/resource/integration/). Valid values are `HTTP` (for HTTP backends), `MOCK` (not calling any real backend), `AWS` (for AWS services), `AWS_PROXY` (for Lambda proxy integration) and `HTTP_PROXY` (for HTTP proxy integration).
+* `type` - (Required) The integration input's [type](https://docs.aws.amazon.com/apigateway/api-reference/resource/integration/). Valid values are `HTTP` (for HTTP backends), `MOCK` (not calling any real backend), `AWS` (for AWS services), `AWS_PROXY` (for Lambda proxy integration) and `HTTP_PROXY` (for HTTP proxy integration). An `HTTP` or `HTTP_PROXY` integration with a `connection_type` of `VPC_LINK` is referred to as a private integration and uses a VpcLink to connect API Gateway to a network load balancer of a VPC.
+* `connection_type` - (Optional) The integration input's [connectionType](https://docs.aws.amazon.com/apigateway/api-reference/resource/integration/#connectionType). Valid values are `INTERNET` (default for connections through the public routable internet), and `VPC_LINK` (for private connections between API Gateway and a network load balancer in a VPC).
+* `connection_id` - (Optional) The id of the VpcLink used for the integration. **Required** if `connection_type` is `VPC_LINK`
 * `uri` - (Optional) The input's URI (HTTP, AWS). **Required** if `type` is `HTTP` or `AWS`.
   For HTTP integrations, the URI must be a fully formed, encoded HTTP(S) URL according to the RFC-3986 specification . For AWS integrations, the URI should be of the form `arn:aws:apigateway:{region}:{subdomain.service|service}:{path|action}/{service_api}`. `region`, `subdomain` and `service` are used to determine the right endpoint.
   e.g. `arn:aws:apigateway:eu-west-1:lambda:path/2015-03-31/functions/arn:aws:lambda:eu-west-1:012345678901:function:my-func/invocations`
