Account and API Security

Configure the access controls available for your account and verify signed requests and callbacks in your integration.

Credential Protection

Provider credentials are encrypted in storage. Merchant API requests use credentials and HMAC signatures; keep your signing secrets on your server.

Authentication & Signatures

Merchant API calls verify HMAC-SHA256 signatures and timestamp freshness. Two-factor authentication protects admin access.

Access Controls

Configure API and panel IP allowlists and assign merchant employee permissions. Audit logs record administrative actions.

Account Setup and Fees

Payment fees, limits and enabled flows depend on your approved merchant configuration. Review these before accepting live payments.
