How to pass dynamic parameter to the JSON as a data source

[Anonymous]

Hi,

I'm accessing the REST API URL as a direct query data source through the CData Power BI Connector for REST but the current URL has a hard coded value but how could I pass parameter dynamically in the power bi.

I have created 2 columns in the schema (JSON) which can be used as a parameter- pease see the below

<input name="effectiveDate" required="true"/>
<input name="prodId" required="true"/>

and change the URL to http://hotsname/sources/DimSales?rs:effectiveDate=[_input.effectiveDate]&rs:prodId=[_input.prodId]&rs:pageSize=10000&rs:pageNumber=1" 

And also created Parameters in the Power BI with the same names (effectiveDate, ProdId) but got the below error.

Any suggestion would be much appriciated,

Thanks

Hi @Anonymous 

Do you create query parameter in Edit queries?

If so, when using parameter in URL, you could refer to the similar threads below:

@v-juanli-msft , Thanks for your inputs, 

With the Power BI Service URL query string parameters will filter the report, but they will not change report parameter values, i.e. it will not re-execute the data source with the values passed in the URL.

Plese see the below an overview of my target.

I'm using the Datasource : REST API i.e http://ABC/datasources/Products?rs:Date=2020-01-02 and its running fine and getting data as i am passing all parameters dynamically but It is not pulling the data by changing the URL parameter once I Published the Report to Power BI Service .

I'm not sure whether, this can be achieved as of my knowledge Power BI Query string parameters are for filtering the data and it will not re execute the datasource to get new data.

I found that, Currently it is not possible to pass the query level parameters from the Power BI Service either Embedded URL or Report URL.
