I checked that the DOMO Governance or Stats connectors don't have the tag data of datasets or dataflows.
In the DOMO API documentation, I couldn't find any endpoints or even a way to filter by a specific tag.
Is there another API? I'm looking at https://developer.domo.com/docs/dataset-api-reference/dataset#List%20DataSets
I'm not sure the API has kept up with that added feature yet but it is definitely something they should add. Maybe add it to the idea suggestion area for a future improvement.
Or you could upvote my idea:

And you are looking for the tag on the dataset, not the tags for the specific fields on the dataset.
Let me do some digging around. I'm not aware of any off the top of my head though.
