Hello.

I’m looking for advice on how-to solve following problem:  
I’m building multiple APIs on AWS using AWS Lambda and API Gateway. Client wants a custom domain under which all of these standalone APIs are to be mapped. There is a guide to this here:

> **[How to deploy multiple micro-services under one API domain with Serverless](https://www.serverless.com/blog/api-gateway-multiple-services/)**
>
> Learn how to use the same domain name for multiple Serverless services with API Gateway base path mappings.

But my case differs here. My APIs and Lambdas are deployed under different account than the Route53 resources are. Client can provide me with IAM role with which I could do the actions needed to be done in/on Route53 with serverless-domain-manager but I have no idea how to do this with serverless and/or serverless-domain-manger. How to set this up? I could use some tips on what I should do if serverless is not up to the task and need to set this up manually.

Thank you for your help in advance.
