how to structure complex Web.Content Query parameters

Hi all

I'm trying to format my API call from this:

Source = Json.Document(Web.Contents("https://portal.example.com/api/v1/search/domains?query=example.com&relationships[]=account&relationships[]=account.partner"

to use RelativePath and Query parameters:

    Source = Json.Document(
        Web.Contents(
            BaseURL,
                [
                    RelativePath = Entity,
                    Query = [
                                query = Domain,
                                relationships = ???????
                            ],
                    Headers = [
                                Authorization = APIKey
                            ]
            ]
        )
    ),

The issue I'm having is that I don't know how to structure the "relationships[]=" part into the proper format. The format that the call returns (when using the first format shown above) is this:

        }
    }
]

The reason I'm trying to convert it is that I'm making this a part of a dataflow, but it won't save if I use the first format, as it says it's a dynamic query. 

Would appreciate any help on this.
