Is it possible to use AWS API without Authentication Token

Question

I try to use AWS lambda. I don't want to use any authentication - it is a simple test function. I receive

{
    "message": "Missing Authentication Token"
}

Is it possible to use AWS API without Authentication Token?

Thanks in advance.

Yes, it's possible. You can configure if you want to use Authorization, Request Validator or API key for each resource you created.

Also make sure you invoke the right URL and path of your API, because I had the same issue when I tried to trigger an undeclared path.
