Recently I had the need to create a Lambda function with PowerShell 7. The function is to synchronize data between two REST APIs. It’s fairly simple, but does need to use a custom made module. I spent quite bit time to find out how to deploy PowerShell Lambdas with custom modules. Thought might write a guide to help people want to do the same. My script is fairly simple, it gets a list of users from one API and then convert it to a XML format object and export into the target API.
