Create or Update (PUT)

Use PUT /v1/tags instead of POST to perform an upsert. If a tag with the same fullyQualifiedName already exists, it will be updated; otherwise, a new tag is created. The request body is the same as POST.

curl -X PUT "{base_url}/api/v1/tags" \
  -H "Authorization: Bearer {access_token}" \
  -H "Content-Type: application/json" \
  -d '{ ... same body as POST ... }'

PUT will not return a 409 conflict error if the entity already exists — it will update the existing entity instead.

Error Handling

`401`	`UNAUTHORIZED`	Invalid or missing authentication token
`403`	`FORBIDDEN`	User lacks permission to create tags
