Type Alias AuthToken

JWT for the Upload API Authorization: Bearer <token> scheme. Accepts a plain token or a resolver function; the resolver is called before every request, so long-running uploads (e.g. multipart) can supply a fresh token mid-flight.

This client never stores a token between calls. Rather than fetching one per request, pass the bound getToken of an AuthTokenCache from @uploadcare/signed-uploads/client, which holds the token and replaces it shortly before it expires:

const tokens = new AuthTokenCache({ fetchToken })
uploadFile(file, { publicKey, authToken: tokens.getToken })
Copy

Mint tokens on your server with generateAuthToken from @uploadcare/signed-uploads — it needs the project secret key.

Takes precedence over legacy secureSignature / secureExpire: when both are provided, only the Authorization header is sent.
