If i make a POST request to API gateway endpoint (configured to handle POST calls), by using AWS console how can i identify which AWS service (lambda/fargate/etc) is configured as request handler for that endpoint.
https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-basic-concept.html
suggest For Integrations, choose Add integration.
But how can i find handlers/integration for an existing endpoint.
I am only able to identify Invoke URL and lambda service used as authenticator. OR do i need to manually check each Application load balancer ?
If you would like to add Integrate with ALB, you could select the HTTP in Integration Request > Integration Type and input the ALB DNS into Endpoint URL.

I want to deploy my API to AWS, there is an Endpoint URL, but I have no idea what's this
Any help please, thank you.
The HTTP integration will forward any requests to API gateway to your HTTP endpoint which you already must have. For example, you can create some API server of your own on an EC2 instance, and API gateway through HTTP integration will proxy all requests to your instance. In this case, the HTTP endpoint will be your EC2 url.
But if you don't know what is your HTTP endpoint, then probably you don't need to use HTTP integration. Maybe lambda integration would be better.
Currently I am using the API Gateway as a kind of proxy to provide https simply
https://random-aws-name.com => http://my-domain.com
The route was $default
The integration setup is HTTP ANY -> http://my-domain.com
I am now having to setup an Websocket server on my domain that is already listening at ws://my-domain.com. I can connect directly to this socket but not using the AWS API Gateway
wss://random-aws-name.com => ws://my-domain.com
Currently I an getting unexpected error 400, using wscat
I tried to enable API gateway logging and do not see any log arrive
IMHO, AWS API Gateway is only able to provide a wss end point and route requests to HTTP backends only. If we already have a backend websocket server, I don't see an option in AWS API Gateway to perform such routing (Although I would be glad to be proven wrong as I have such a requirement myself.).
I actually tried giving wss:// url as the Endpoint URL but I got an error while deploying the API saying Invalid HTTP endpoint specified for URI
Most likely, the API Gateway you are currently using is not a WebSocket API, but rather an HTTP API or REST API. API Gateway has different flavors. You pick a flavor when you deploy. The flavor that you deployed is most likely not the flavor that supports WebSocket connections.
According to this documentation page, proxied WebSocket connections may only be one-way (note in blue box at bottom of page): https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-websocket-api-routes-integrations.html
I have a set of microservices running on ECS which are deployed behind the API Gateway which forwards the client calls to the service endpoints.
I would like to use correlation (request) IDs in my services so that I can easier relate the events and everything that happens on the backend and the client requests.
Is there a possibility to configure AWS API Gateway to automatically add auto-generated (unique) correlation ID as a header of the request before it's forwarded to my backend services?
I need to make a secure HTTP callout from Salesforce (using Apex) to AWS Lambda and I build my first version using AWS API Gateway. I realized I can get a client certificate from API Gateway (.crt) but this looks like it is only for AWS backend and is not meant to be for the HTTP request sent to API Gateway. What are my alternatives to establish a secure connection from outside AWS (Salesforce) to a Lambda function?
So far I've found this, which is a disappointing dead-end for now.
Like the link you posted says, API Gateway does not currently support MTLS. Other options for you to add security to the calls at the moment are:
IAM permissions, and here.
API Gateway custom authorizers.
Cognito User Pools.
If you need a custom domain associated with the API Gateway:
Go to Route53 and add your domain (new Hosted Zone), if you haven't done it already.
On AWS Certificate Manager, import or request a certificat for the custom domain you intend to use in your API Gateway endpoints.
Open the API Gateway dashboard and go to "Custom Domain Names". Click "Create a custom domain name" and, in the option "ACM Certificate (region)", select the certificate you generated/imported in item 2 above.
That's it, now you should be able to trigger your Lambda functions using API Gateway from a secure connection (HTTPS). Please note that, if you do this, API Gateway will refuse connections over insecure HTTP protocol.
I am looking to build an API orchestration layer using API Gateway and Lambda.
For my basic use case I want to have a Python script in Lambda that will just relay the request received at the API Gateway from the client (mobile app in this case) and call an external HTTPS service as the backend.
My question is:
Our mobile client uses client certificates to talk to our HTTPS endpoint today.
How do I go about intercepting that client certificate in my new API Gateway + Lambda setup?
Responded here. Copying the answer below for StackOverflow audience-
===
Unfortunately, API Gateway does not support client certificate validation from clients to API Gateway at the moment. We do, however, support client side SSL certificates for authentication by the backends.
Depending on your use-case, you can use various other options in API Gateway to authenticate/authorize your calls from the mobile client; eg API Keys, Custom Authorizers etc. The request from API Gateway to Lambda should already be encrypted.
Hope that helps,
Ritisha.
