# Assign a tag to a contact

POST https://app.brightmove.com/ATS/api/v1/client-contacts/{guid}/tags
Content-Type: application/json

Assigns a tag (by name) to this client contact. If no tag with this exact name exists yet
for the company, one is created.

Assigning the same tag more than once has no additional effect.

The tag name is passed in the request body, not the URL path, since tag names may contain
characters (spaces, slashes) that don't survive path encoding cleanly.
