Currently only GET requests are supported as data source. A 3rd party systems use POST request to provide data.
POST API needs to implemented in Power Bi. As most of the governament systems (I am part of using it) are old and use XML and SQL connection. I performed XML POST API request from server and could update through Power Bi Desktop version, but as soon as i published it and put auto update, it refused. I and others like me feel this problem needs to be addressed.
