We read every message and usually reply within a few business days.
Help us help you
The API
Tell us the request you made and the response you got. Never send your API token: we will never ask for it.
Team boards
Include your board's public link. Keep invite links and personal edit links to yourself: anyone who has them can join or edit.
A data error
Send the page and what's wrong, plus a source if you have one. We check reports against the tz database and correct confirmed errors.
