I have 1 Lambda Function connected to AWS Oracle RDS. I have exposed lambda to outer world via API Gateway.
How can i access same API Gateway in my EC2 Instance where i have my back-end services running?
[ec2-user#ip-22-22-22-22 dummy]$ ./telnet 10apexecute2.execute-api.eu-west-1.amazonaws.com 443
Trying 55.11.144.98...
Please help
As the account must be restrictive with its outbound communication over internet, the suggested solution would to make use of a VPC endpoint for API Gateway.
Once you create this endpoint, make sure to enable the "Enable Private DNS Name" option to override the DNS resolution for execute-api endpoints to speak to resolve through your VPC endpoint.

weird functionality with AWS execute-api VPC endpoint and wondering if anyone has found a workaround?
Let's say there is a lambda function running inside VPC and it has API gateway pointing to it. On top of that, VPC has execute-api VPC endpoint with private DNS enabled, so that the API gateway DNS name returns the internal IP instead of public IP.
Above works fine but the downside is that now it prevents us connecting to some other AWS accounts API gateway as all the api-gateway subdomains are now resolving to internal IPs?
Any workaround on this?
Didn't find any solution, so decided to create yet another VPC where execute-api VPC endpoint is not enabled and moved external connection components into that VPC.
Using AWS Direct Connect, we've built a network between our on-premise and our AWS VPC. We've developed a web application that users will access from within the on-prem network. We're using the HTTP API Gateway, which uses a VPC Link to connect to the private ALB. We've used a Custom Domain Name with the HTTP API Gateway and disabled the default endpoint. The domain name is registered in a private hosted zone on Route 53.
We want to keep all the traffic between the clients and the API Gateway within our private network. However, we can see that the requests going to the HTTP API Gateway leave our network because the custom domain name for the API Gateway resolves to a public IP address.
Is there a way to assign a private IP address to the HTTP API Gateway? Or any other way to keep the traffic within our network?
One option is to switch to the REST API Gateway and make its endpoint type Private. However, the HTTP API Gateway suits our needs much better with its simplicity. It also has the option for connectivity to an ALB using VPC Link, which the REST Gateway lacks.
Sadly no, the HTTP APIs do not support Private APIs. Whatever solution you will use, HTTP API endpoint must be public.
You have to use REST API, or create your own fully custom solution if REST API is out of question.
I want to provide an update to this topic.
AWS updated its product and private endpoints are available right now.
AWS - Private API endpoint
There are also a couple of examples out there also for CDK, Cloudformation or management console.
I hope this helps
I have a problem configuring my AWS API Gateway:
I have an API deployed in an EKS cluster, and it has a public load balancer, so right now, this API is accessible from everywhere. I want to allow access to this API only from AWS API Gateway, so if anyone wants to use the API, it has to be through AWS API Gateway.
The problem is that I don't know how to allow traffic to the API only from API Gateway. I tried using a security group, but AWS API Gateway IP changes all the time. I tried also using an internal load balancer in my Kubernetes deployment, but AWS API Gateway can't reach that loadbalancer!
Thanks in advance with the help!
You can do this by using a Network Load Balancer.
Create an internal network load balancer and have your containers be added to its target group.
Then in API Gateway create a VPCLink to your Network Load Balancer. Then use the VPCLink within your API Gateway setup.
More instructions available here.
You might be able to accomplish this by setting up an API Gateway private integration. This makes it simple to expose your HTTP/HTTPS resources behind an Amazon VPC for access by clients outside of the VPC.
Also, have a look at Amazon EKS cluster endpoint access control in order to understand how you can enable endpoint private access for your cluster.
With AWS API Gateway, is there a way to send a request through a corporate proxy? Let's say that I have a service that will only accept traffic sourced from http://proxy.my-proxy.domain.com:8000.
If the above is not possible, is there a way to send requests with an IP from my VPC CIDR?
NOTE - This is a private API Gateway with all VPC-E configured
correctly.
NOTE - As I am merely a simpleton, I do not have
privileges to modify this proxy.
NOTE - I'd rather not use lambda (if
possible)
Private endpoints are only private within the AWS ecosystem, they cannot be utilized outside them unless you establish connectivity between AWS VPC and your corporate network.
There are three ways to achieve this as far as i know
You can make your API Gateway be public and use WAF to control access to it. You can whitelist only your corporate proxy IP addresses that are only allowed to access this gateway.
Establish a VPN connection between your AWS VPC and the corporate network. This will allow you to use private endpoints without making them public using a secure encrypted pipe
Setup AWS Direct Connect between your AWS VPC and the corporate network. This may not be an option considering the cost to the value proposition
I just ended up using Lambda attached to my VPC w/ API Gateway proxy integration.
Is there a way to set up api gateway endpoint for lambda functions to be only accessible internally ? I don't want it to be expose to the public.
API Gateway has released a new Private Endpoint feature, which makes this possible.
The API Gateway Private Endpoint will only be accessible from VPC and it requires setting up an Interface VPC Endpoints which will be used to access the endpoint. Also, it will be required to setup a Resource Policy to grant access to the API from your VPCs and VPC endpoints.
In order to access the API endpoint from your on premises network, you can either establish a AWS Direct Connect connection or AWS VPN Connection from your on premise to the Amazon VPC.
Unfortunately, no. At the moment API Gateway Invoke URLs are public. Making them private is not possible.
You can secure your API Gateway Rest API using either IAM roles or custom authorizers.
Yes, now you can configure AWS API Gateway with private link. follow the link, but you can only access the endpoint from VPC and if you want to access that end point from your data center you will need Direct Connect.
