Connecting a domain
You can connect your own domain to access the API gateway. You can connect multiple domains to a single API gateway. In this case, the domain is identified by the Host header.
Warning
This must be a third-level domain or higher (for example, www.example.com). This has to do with how CNAME records are processed on DNS hosting. Learn more in RFC 1912, Section 2.4.
To connect a domain to an API gateway:
-
Host a CNAME record with your DNS provider or on your own DNS server:
<domain> IN CNAME <API gateway service domain>How to find your API gateway service domain- Go to the management console.

Issued, create a domain. In the Certificate field, select the certificate that you created in Step 3.1.
