I've configured my API gateway to work with mTLS authentication and it’s working fine.
Now, I need to add a new API gateway with API Key authentication on the same custom domain but can’t find a way to do it.
Is there any way to define the authentication method for a specific API gateway under the same domain?
Mutual TLS (mTLS) is configured at the custom domain level in API Gateway. This means that when mTLS is enabled for a custom domain, it applies to all APIs under that domain.
If you want to use API Key authentication for a specific API, you need to use a different custom domain.
