What are the limitations and disadvantages of creating an api gateway using yaml?

[karimfayed]

I'm currently a beginner when it comes to using AWS CDK. I want to create an API Gateway using a YAML file and import it using CDK.

From my limited understanding, I have to write or declare lambda inside the YAML file and this will require me to overwrite the ID given by AWS to the lambda. So I would like to ask the following:

Are there any other limitations or disadvantages to this scenario?

Is it a good idea to proceed with this method or should I just create the apis using normal CDK?

If it is ok to go with this method, can you share a resource or a guide on how to do so?
