Google Datastudio Connector

I want to create a google data studio connector which needs to visualise json data we are generating from our app. An example of the returned json is added as a file and the chart output image is also added as a file. The api call to get the json has defined parameters (the dimension to be retrieved, the metric, the time period, and the return type: https://apicall/api/metrics/dateHistogramMetric?bucketField=country_name.raw&size=2500&site=thesite&apiKey=the-api-key&startTime=1637708400000&endTime=1669330799000&timezone=%2B01%3A00&typeName=session&termFilters=&interval=1w&include=unknown These parameters need to be configurable. Upon choosing you, we will work together to work out any details.
