}Authorizations
Your business API key (live_key_...). Issued on approval; managed in Dashboard → Settings → Developer.
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.
Body
application/json
Card product code (drives currency + card type). Discover available products via GET /business/card/products.
Example:
"USD_VIRTUAL"
Card type. Every card is a wallet-enabled USD card, so this is optional — omit it, or send APPLE_PAY or GOOGLE_PAY to issue a wallet-enabled USD card the cardholder can add to Apple/Google Wallet. Numero routes to an issuer that supports it.
Available options:
USD, APPLE_PAY, GOOGLE_PAY, null Example:
"APPLE_PAY"
USD loaded onto the card at issue (debited from your USD card wallet).
Example:
5
Example:
"visa"
Friendly card name.
Example:
"Ads spend"
Example:
"NG"
Example:
"PASSPORT"
ID-document image URL — required by some issuers.
