Dynamic values in paramater

[jitpbi]

Hi,

I am using the below paramters to pass in the URL to get the data from a web source which based on the start date and end date:

the below is from Advance Editor:

let
Source = Json.Document(Web.Contents("http://175.20.9.16:41000/PS/v1/ABC/Device/Meter?start_time=" & DeviceSD & "&end_time=" & DeviceED))

in

Source

I can successfully get the data for these paramaters (hard coded date), Now my requirement is to make these current values dynamic. The current value for the parameters "DeviceED" should be current datetime (like now()) and "DeviceSD" should be 3 days back datetime (like now()-3) rather than passing a hard coded datetime values.

Please suggest how to achieve this.

StartDate

EndDate

Hi @jitpbi,

Perhaps you can try to split your url string and add optional parameters 'relative path' and 'query' to confirm if they works on power bi service side:

let
	url="http://175.20.9.16:41000/",
	Source = Web.Contents(url,
				[
					RelativePath="PS/v1/ABC/Device/Meter",
					Query =
					[
						start_time =
						DateTimeZone.ToText(DateTimeZone.From(Date.AddDays (DateTimeZone.UtcNow(),-3)),"yyyy-MM-ddThh:mm:ssZ"),
						end_time =
						DateTimeZone.ToText(DateTimeZone.UtcNow(),"yyyy-MM-ddThh:mm:ssZ")
					]
				]),
	Result=Json.Document(Source)
in
	Result

Using The RelativePath And Query Options With Web.Contents() In Power Query And Power BI M Code
