Dynamic Datasource automatic refresh

Dear arvindsingh802 ,

thank you very much for your reply. I have now this code, however get a 404 error message as I don't know where to put the [Headers=[#"Content-Type"="application/xml"]] Part:

Xml.Tables(
        Web.Contents(
            "https://transparency.entsoe.eu/api",
            [
                RelativePath="",
                Query=
                [
                    securityToken="MYTOKEN",
                    documentType="A75",
                    processType="A16",
                    in_Domain=#"ENTSO-E-Zone-DE",
                    periodStart="202112312300",
periodEnd=Date.ToText(Date.AddDays(Date.From(DateTime.LocalNow()),-1),"yyyyMMdd")&"2300"      
                ]
            ]
        )
    )

Can you help me out?

Best regards

Manuel
