Serverless Stack

is there a guide on how to set up custom domains without using route53, or is this not supported?

here's an example: <https://docs.serverless-stack.com/constructs/v1/Api#using-externally-hosted-domain>

The thing that's tricky is your ApiG needs to serve a valid certificate, you should just be able to do `new Certificate` and aws will email you to confirm ownership of the domain

that example imports an already existing cert (if you created it in the ui)

```      cdk: {
        certificate: new Certificate(props.stack, "cert", {
          domainName: dns.domain,
        }),
      },```

and that doesn't always create a new certificate for each deployment?

ah, or, I guess it doesn't really matter if it's always a new cert, as long as it's valid?

it won't create a new cert every deployment, remember with the way cloudformation works it only makes changes if your stack definition changes in a meaningful way

just like doing `new StaticSite` won't create a new one every deployment

<@U02JTBH4883> where is ur domain hosted? We will add an example for the domain registrar.

<@U01MV4U2EV9> I tried it like this, but get the error message `A valid certificate is required when "isExternalDomain" is set to "true".`
```         customDomain:
            scope.stage === "prod" ? {
               isExternalDomain: true,
               domainName: "<http://api.mydomain.com|api.mydomain.com>",
               cdk: {
                  certificate: new Certificate(this, "apicert", {
                     domainName: "<http://api.mydomain.com|api.mydomain.com>",
                  }),
               },
            } : undefined, ```
