Where should I add my custom resolver CloudFormation config?

I’m following the steps here https://aws-amplify.github.io/docs/cli/graphql#add-a-custom-resolver-that-targets-an-aws-lambda-function but in the steps that says: Add the function as an AppSync data source in the stack’s Resources block.. Ok, but, and the template? which one? amplify\backend\api\myapi\stacks\CustomResources.json or should I add a new one in _amplify\backend\api\myapi\stacks_? Obviously, it is not in the Lambda’s template because of the parameters S3DeploymentBucket and S3DeploymentRootKey are not injected/passed to the Lambda’s template, right?

I think the documentation is not clear about the process and should be updated accordingly.

I agree that the docs for adding a custom resolver should include a link to https://aws-amplify.github.io/docs/cli-toolchain/graphql#api-category-project-structure . In fact, I really wish I had read about the API Category Project Structure a long time ago. Until I read that section, I had no understanding of what amplify push was actually doing or how it worked. I think it would be a good idea to make that article much more prominent than it is now. You have to go really deep in the docs past a lot of advanced topics to find it right now, but it really should be one of the first things you read when learning about Amplify.

@zjullion You should be able to reference the ApiId directly from the stacks paramters. Here is an example:

The parameter definition that you can add to your template:

Example usage of the parameter:
