Using Console
Using Console
- Log in to the AWS Management Console and navigate to the API Gateway service.
- In the API Gateway dashboard, select the API you want to inspect.
- In the API details page, select the “Resources” option from the left-hand side menu. This will display all the resources and methods associated with the selected API.
- For each method, click on the method request to view its settings. Under the “Settings” tab, check the “Endpoint Type” field. If it is set to “Edge Optimized” or “Regional”, it means the API is publicly accessible. If it is set to “Private”, it means the API can only be accessed from within your VPC or via a VPC endpoint.
Using CLI
Using CLI
- First, you need to install and configure AWS CLI on your local machine. You can do this by following the instructions provided by AWS. Make sure you have the necessary permissions to access the API Gateway.
-
Once the AWS CLI is set up, you can list all the APIs in the API Gateway by using the following command:
This command will return a list of all the APIs in the API Gateway.
-
To check the endpoint configuration of each API, you can use the following command:
Replace
{rest-api-id}with the ID of the API you want to check. This command will return the details of the API, including its endpoint configuration. -
To check if only private endpoints can access the API, look at the
endpointConfigurationfield in the output. If thetypesfield underendpointConfigurationcontains “PRIVATE”, then only private endpoints can access the API. If it contains “EDGE” or “REGIONAL”, then the API can be accessed from public endpoints.
Using Python
Using Python
- Import the necessary AWS SDK for Python (Boto3) modules and initialize a new client for the API Gateway service.
- Fetch all the APIs in the API Gateway service.
- For each API, get the endpoint configuration and check if it’s a private endpoint.
- The above script will print out the names of all APIs that are not private endpoints. If no APIs are printed, then all APIs are private endpoints. If some APIs are printed, then those APIs are not private endpoints and are misconfigured.
