You configure VPC Endpoint which provides private access to the private API in the API Gateway.

1. Goto VPC Management Console. Click on the Endpoints menu in the left and then click on the Create Endpoint button.

   

2. On the next screen, select AWS services for the service category. Select com.amazonaws.eu-west-1.execute-api for the service name. Select the default VPC for the VPC field. Select all three subnets of the VPC. Check Enable DNS name option. Select dojo-api-sg as the security group. Select Full Access for the policy and finally click on the Create endpoint button.

   

   

3. The endpoint is created. You make note of the Endpoint Id once the endpoint is ready as you need it later when configuring and calling the private API.

   

4. In the next step, you create the Lambda function which works as the backend for the API in the API Gateway.
