Gateway IDs when no gateway is set up

[jjgray-sl]

I'm trying to use the Update Datasource endpoint of the Power BI REST API to update a datasource's credentials. The call requires the gateway ID of the datasource. 

I don't have any gateways set up. I'm connecting to Snowflake via the native Power BI connector which does not require use of a gateway. Is this endpoint able to update a datasource that is not part of a gateway? If so, what ID should be using?

Thanks @lbendlin for the link. The endpoint you've shared seems to be deprecated, but it's replacements Datasets - Update Datasources and Datasets - Update Datasources In Group commands would be able to update datasets.

However I've created the datasets using the Power BI XMLA endpoint. This makes the datasets incompatible with those endpoints. The Gateways - Update Datasource endpoint does not have this limitation, so I've been trying to use that. 

I've been able to find the hidden gateway ID by reading metadata from a dataset object when getting all datasets. Ideally there'd be a nicer way to find it though

You may be in the wrong aisle of the API library. Try here
