requestMessage, type: Object
customHeaders, type: Dictionary<String, List<String>>
Documentation for posting rows can be found here:
as far as i know the requestMessage is the object used for the data you want to add.
the way i did this was took a newtonsoft JSON object and deserialized it to an object: (data being my JSON object)
object dataObj = Newtonsoft.Json.JsonConvert.DeserializeObject<Object>(data.ToString());
as for the customHeaders as far as i know its for adding to the header of the http request that the api will create. i think it can be used to add scope, roles and others configurations but I'm not 100% sure because the documentation is still very much lacking. Also note that its only optional.
For the Power BI embedded REST API, how do I add rows to a table?
AFAIK, there's no REST API to add rows for Power BI Embedded, you can submit your idea at Power BI Ideas and vote it up.
