Exporting Metrics - Error when following example revenue API call

Hello,

I am trying to use Postman to make an API call to get the revenue generated by a specific campaign. Per this doc, I am making a GET request to the following endpoint: 

https://a.klaviyo.com/api/v1/metric/PLACEDORDERMETRIC/export

In my Klaviyo account, I have navigated to a URL that looks like this:

https://www.klaviyo.com/metric/KDbUXb/feed/placed-order#dimension=$attributed_message&value=YeniMY

So in the endpoint URL I have replaced PLACEDORDERMETRIC with KDbUXb

For params I am following the exact suggestion of the doc:

api_key=API_KEY (I have replaced API_KEY with my API key)

unit=’week’

measurement=’value’

where='[["$attributed_message","=",'YeniMY']]'

But it seems I am getting two errors, here is the response:

{
    "status": 400,
    "message": "* unit\n  * Select a valid choice. 'week' is not one of the available choices.\n* __all__\n  * Invalid where clause."
}

Any ideas what I am doing wrong?

Thanks,
Zach
