Methods available to datamart API

gbrueckl 

I ran the following method on datamart just to test if refreshes method is avaialble to datamart apiPath ( as it is availabale to dataset apiPath)

-- the following returns error on datamart
%%sql

WITH cte_workspaces AS (
    SELECT explode(pbi_api_udf('/groups', '${pbi_access_token}')) as workspace
)
, cteTwo as (
select workspace.name as workspace_name,workspace.id as workspace_id,workspace.apiPath as workspace_apiPath
from cte_workspaces
WHERE workspace.name = 'Production'
    )
, cteThree as (    
select * 
    ,dm.apiPath as apiPath
from cteTwo
LATERAL VIEW explode(pbi_api_udf(concat( workspace_apiPath, '/datamarts'), '${pbi_access_token}')) AS dm
)
select *
from cteThree
LATERAL VIEW explode(pbi_api_udf(concat( apiPath, '/refreshes'), '${pbi_access_token}')) AS refreshes



-- the following works perfectly on dataset (semantic model)
%%sql

WITH cte_workspaces AS (
    SELECT explode(pbi_api_udf('/groups', '${pbi_access_token}')) as workspace
)
, cteB as (
select 
    workspace.name as workspace_name
    ,workspace.id as workspace_id
    ,workspace.apiPath as workspace_apiPath   
    ,datasets.name as ds_name   
    ,datasets.apiPath as apiPath  
from cte_workspaces
LATERAL VIEW explode(pbi_api_udf(concat(workspace.apiPath, '/datasets'), '${pbi_access_token}')) datasetsTable AS datasets
WHERE workspace.name = 'Production'
    )
select * 
FROM cteB
LATERAL VIEW explode(pbi_api_udf(concat( apiPath, '/refreshes'), '${pbi_access_token}')) AS refreshes

But it returns {"error":"Not Found","status_code":"404"}

How am I to know, what methods are avaialble to the datamart apiPath? Does there exists a documentation that says what methods are available to what artifacts?
