Create API Mapping with Cloudformation and Api Gateway V1

Question

I have created an AWS Api Gateway (edge optimized) with CloudFormation. So far, everything works great. Now I´d like to make that API available under a custom domain, so I also added a custom domain resource to my CFN scripts. However, I do not see any possibility to also create an API mapping with CFN. If I create that manually, everything works fine, but I want do have it as part of the CFN scripts. I´ve seen in the documentation, that there is an ApiMapping available for Api Gateway v2 resources, but as per my understanding this does not work with edge optimized APIs. Can you help me here?

Kind regards

You need a BasePathMapping resource to map a custom domain to a "v1" REST api. — 404

The BasePathMapping indeed did the trick. That was not that obvious in my opinion, since the documentation nowhere states the purpose of that resource. Thank you.

May be worth noting that API Gateway V1 doesn't support the slash character (/) in base path mappings. To create a multi-level base path mapping (e.g. v0/users), we need to use API Gateway V2.
