https://company_subdomain.talkpush.com/api/talkpush_services/company/labels
Creates a new label for the company. The label becomes available in the UI immediately and can be assigned to candidates via PATCH /campaign_invitations/{id}.
Duplicate prevention: If a label with the same name already exists, the API returns 409 Conflict. This is enforced both before saving and after, so a concurrent create with the same name still maps cleanly to 409 (never a 422 validation error).
Name rules: Names are trimmed of surrounding whitespace. Names containing ,, # or ? are rejected with 422.
Missing, invalid, or inactive API key.
Internal server error; the response may include an exception message.
