Authorizations

X-Numero-Api-Key
string
header
required

Your business API key (live_key_...). Issued on approval; managed in Dashboard → Settings → Developer.

X-Numero-Signature
string
header
required

Base64(HMAC-SHA256(publicApiKey, input)) over the raw request body (POST) or canonicalized query string (signed GET). Also send X-Numero-Signature-Version: v2. Required on money-movement / state-changing endpoints (marked 🔒).

The HMAC key is your Public Key as raw UTF-8 bytes — a SECRET despite the name, and a different value from the X-Numero-Api-Key authentication header. Signing with the API key will never produce a valid signature.
