Filtering on Managed Metadata - MS Flow

Question

So apparently managed metadata fields are not supported with ODATA Filter Queries in MS Flow. We need a workaround so we can filter the results from a 'Get items' action. Does anyone know a clever way (besides copying the metadata to a text field) to filter on managed metadata using Flow?

Answer 1

If you have a list named Test that contains a managed metadata field named Department, you can get all of the items where the value of the Department field is Accounting using the following SharePoint REST API POST request:

_api/Web/lists/getByTitle('Test')/GetItems(query=@v1)?@v1={"ViewXml":"<View><Query><Where><Eq><FieldRef Name='Department'/><Value Type='TaxonomyFieldType'>Accounting</Value></Eq></Where></Query></View>"}

In Flow you would use the Send an HTTP request to SharePoint to make that REST API call.

You could then use a Select action to extract the values you need from the response. In the example below I'm selecting the value of the Title field.

The value of the From expression is: body('Send_an_HTTP_request_to_SharePoint')['d']['results']

The value of the Title expression is: item()['Title']

Answer 2

There is a workaround for this issue is adding a Condition. Then use the dynamic content of Managed metadata label to check if it equal to the specific value.
