Both of those should have separate static functions that you can call - if you want to retrieve the state of an existing resource there should be a pulumi static function to do so and return the result as an Output

To be more specific, there should be a function for that specific resource type. For instance, this is the function to get an existing AWS S3 Bucket

The above

getBucket

function will query AWS and get the current state of a bucket that may or may not already exist in your stack. While this

Bucket.Get

function here will instead not query AWS at all, and will retrieve the state of an existing Bucket resource that already exists in your stack directly from your pulumi state. So it depends what you want to do. Btw none of this functionality is specific to automation API, this is just pulumi program functionality.
