Authentication

Create a key under API keys. Keys start with ft_live_. We store only a hash. If you lose the secret, revoke it and create another. You can keep 10 active keys.

Header

Authorization: Bearer ft_live_your_key

A missing, revoked, or unknown key returns 401. A key on a Free or Pro account returns 403. Upgrade that account to Plus, or create the key from a Plus account.

The upload_headers on a signed upload are only for putting the file into storage. They are not a substitute for your API key.
