Could not find it in the help? Write to us or book a call. A person at certo reads every message and answers it.
For anything: your passport, your company account, the API, or a request about your data. We answer from the same address.

- Try Ask the help center first: the button at the bottom right answers from these pages, with links to them.
- If certo showed you an error, open its Details, press Copy details and paste them into your e-mail. They tell us exactly what happened.
- Never send us a sign-in code or an API key. We never ask for either.
