Multiple Calls When Consuming Rest APIs

[powerbi1]

I have a Web Data Source that is using REST calls to pull data and everytime the datasource is refreshed (both from power bi desktop and scheduled refresh on a worksapce) it makes multiple GET API calls on the web server even though i only doing the resfhesh once.

The source that i am usign on the query looks like the below:

Source = Xml.Tables(Web.Contents("https://api_url"))

The above although executed only once it creates at least 2 calls, have seen some rare instances that is 3 calls.

I alslo tried consuming the API using JSON and it seems that using the below produces only one call to the API

Source = Json.Document(Web.Contents("https://api_url"))

I am inclined to switch all my API calls to use JSON.

Does anyone know what the problem may be? Is there a bug with the Xml.Tables() call? Am i missing something?

Thank you!
