power query Velocloud orchestrator REST APIs

[Syndicate_Admin]

Hi All,

Would appreciate some help here if possible as i'm very new to power BI.

Trying to write a query to pull data from the VMware Velocloud orchestrator, which uses REST API's.

The documentation is here: https://developer.vmware.com/apis/1532/

The main thing it uses is POST instead of GET, and requires an authorization key and a few parameters.
I've checked a few of the forum posts here which got me to the following query:

let
Json = Json.FromValue({params={enterpriseProxyId=0}}),
Source = Json.Document(Web.Contents("https://XXX.velocloud.net/portal/rest/enterpriseProxy/getEnterpriseProxyEnterprises", [Headers=[ContentType="application/json", Authorization="Token XXX"]]))
in
Source

Getting a "(404): Not Found" error. 
Anyone able to check the above query and advise where i'm going wrong?

I know the Token and params are correct as i can poll this data successfully using postman and with my python scripts, but just can't do the same in power bi.

Thanks in advanced!

for a POST you need to provide a content payload (can be an empty string)
