I want to use first API response in another Query without call it second time

[ViralGajjar2904]

I am creating new session in below query which name is Create_Session.

let

    BaseURL = BaseURLPara,

    body = "{""sessionId"":null}",

    Source = Json.Document(Web.Contents(BaseURL,

[

RelativePath = "/testAPI/session/create_session",

Content = Text.ToBinary(body),

        Headers = [#"Content-Type" = "application/json"]

    ])),

    newSessionID = Source[data][newSessionID]

in

    newSessionID

This created SessionId I want to pass in below new Query but when I refresh all then /testAPI/session/create_session call two times in backend.I do not want to call /testAPI/session/create_session in below query because I already pass Sessionid using variable (Createsession) then why /testAPI/session/create_session call in below Query?

let

    BaseURL=BaseURLPara,

    Createsession=Create_Session,

    body="{""sessionId"": """ & Createsession & """,

    ""isSearch"": false,

    ""keyword"": """",

    ""exploreType"": 2}",

    Source=Json.Document(Web.Contents(BaseURL,

[

RelativePath="/testAPI/explorer/location_hierarchy",

Content=Text.ToBinary(body),

                Headers=[#"Content-Type"="application/json"]

        ])),

    #"Converted to Table" = Record.ToTable(Source),

    Value = #"Converted to Table"{1}[Value],

    #"Converted to Table1" = Record.ToTable(Value),

    Value1 = #"Converted to Table1"{0}[Value],

    #"Parsed JSON" = Json.Document(Value1),

    #"Converted to Table2" = Record.ToTable(#"Parsed JSON"),

    #"Expanded Value" = Table.ExpandListColumn(#"Converted to Table2", "Value"),

    #"Expanded Value1" = Table.ExpandRecordColumn(#"Expanded Value", "Value", {"EntID", "EntityName", "Name", "Description", "Type", "Icon", "Room"}, {"EntID", "EntityName", "Name.1", "Description", "Type", "Icon", "Room"}),

    #"Expanded Room" = Table.ExpandListColumn(#"Expanded Value1", "Room"),

    #"Expanded Room1" = Table.ExpandRecordColumn(#"Expanded Room", "Room", {"EntID", "EntityName", "Name", "Description", "Type", "Icon", "Floor"}, {"EntID.1", "EntityName.1", "Name.2", "Description.1", "Type.1", "Icon.1", "Floor"}),

    #"Expanded Floor" = Table.ExpandListColumn(#"Expanded Room1", "Floor"),

    #"Expanded Floor1" = Table.ExpandRecordColumn(#"Expanded Floor", "Floor", {"EntID", "EntityName", "Name", "Description", "Type", "Icon", "HasChildren"}, {"EntID.2", "EntityName.2", "Name.3", "Description.2", "Type.2", "Icon.2", "HasChildren"}),

    #"Renamed Columns1" = Table.RenameColumns(#"Expanded Floor1",{{"EntID", "Parent ID"}, {"Name.1", "Site Name"}, {"Type", "Room Type"}, {"Name.2", "Room Name"}, {"Name.3", "Floor Name"}}),

    #"Removed Columns" = Table.RemoveColumns(#"Renamed Columns1",{"Description", "Icon", "Description.1", "Icon.1", "Description.2", "Icon.2"})

in

    #"Removed Columns"

So what is alternate solution?

Hi @ViralGajjar2904 ,

-- Power Query is not suitable for write back, as it will by default execute queries multiple times: The first execution is to retrieve metadata in order to create a query execution plan. After that it will execute the execution plan.
There is no way you can suppress that.
