**Describe the bug** server.workbooks.add_tags() treats spaces in the tag as a delimiter creating multiple tags **Versions** Tableau Server: 2025.1.10 Python version: 3.12.4 TSC version : 0.38 **To Reproduce** workbook_id ="abc123" workbook= server.workbooks.get_by_id(workbook_id) tag1 = "tagOne" tag2 = "tag One" server.workbooks.add_tags(workbook, tag1) #adds single tag "tagOne" server.workbooks.add_tags(workbook, tag2) #adds 2 tags "tag" and "One" **Results** Spaces in a tag creates multiple tags using add_tags(). Spaces are allowed in tags directly in the UI so this creates incorrect tags. ie. "Yearly Sales" will be "Yearly" and "Sales" instead of a single tag. **NOTE:** Be careful not to post user names, passwords, auth tokens or any other private or sensitive information.
