Secure Dispatch

A structured webhook is dispatched to your server, marked with cryptographic secure signatures.

Cryptographically signed requests.

Secret API credentials remain hidden on your local servers. Individual checkout requests are authorized through dynamic HMAC-SHA256 values combined with nonces.

const signature = hash_hmac(
  'sha256',
  rawPayload + timestamp + nonce,
  secretKey
);

HMAC Request Validation Secures the integrity of API streams, preventing frontend manipulation of prices or recipient wallets.

Nonce Replay Safeguard Strict request logging processes discard repeated nonce payloads to defeat malicious retry attempts.

Callback Security Audits Merchant sites check header signatures to automatically mark standard entries verified without manual review.

Directory Indexing Shields Pre-configured deployment scripts bundle structured configurations to prevent unauthorized access.
