Disable Health Check AWS Beanstalk

I've got a node.js server deployed on beanstalk w/ an application loadbalancer. The node.js server has has a URL like the following:

app.get('/data/:id.json', async function (req, res) {
     // do stuff with an API key URL
})

This API key that I'm using here with a 3rd party service (infura, but that's not important), kept getting called approx. 2k times an hour, and I kept trying to figure out why.

I have come to the conclusion that this may be a health check by AWS. Is there a way to disable this so I can prevent my API key from essentially being abused and charging me?

thanks

Depending of the nature of the health checks, but for the many projects, is just a route = url/path like /healthcheck that returns 200.

Keep in mind that the health check is not a functional test, it's just to know the application is alive and responds.

If you want to have a full checking, you can have a custom route ( checking a records in db...) but with a delay in checking not every 5 sec but I don't recommand it at all.

So my suggestion to you, add another route, path like /healthcheck, and return a json response with 200 code like server is ok. For this path do not put any security filter ( like token or api key checking...) and configure it in your beanstalk env.

You may want to change the health check type to EC2 instead of ELB. ELB verifies the specified port is returning 2xx code, while EC2 watches for instance availability only.
