power bi Web custom connector and incremented refresh


I have a power bi desktop custom connector, that use Web.content(url) call to get data from a server

the data is huge, and one of the column is datetime filed (updated_at).

the url can contains Filter option, and I can ask the server to "get only data with updated_at after X and before Y"

I'v created a query with this connector (Get Data -> Connector -> Load)


I wish to use incremented refresh mechanism to get only recent updated_at data on each day

I read about incremented refresh and didn't understand (how to / if I can) use RangeStart and RangeEnd parameters in my connector - so it can sent to the server only this time range


and by using this mechanism (how / if) it collect the data in power bi, and not overwrite the same query over and over again

please help

Thanks for the relpy, but this not answering on how am I using those parameters in the connector code

how a parameter "RangeStart" in the connector relate to the parameter "RangeStart" in the Parameter Manement in power bi?

Hi @LiranRom ,

If you want to configure incremental refresh, there are two requirements:

1. the datasource has datetime type field

2. the datasource support query folding

For how to create RangeStart and RangeEnd parameters, please refer: Configure incremental refresh and real-time data for Power BI datasets - Power BI | Microsoft Learn

For more details, you can read related document: Incremental refresh for datasets and real-time data in Power BI - Power BI | Microsoft Learn , Query folding guidance in Power BI Desktop - Power BI | Microsoft Learn , Query folding - Power Query | Microsoft Learn
