Security & Controls

Every request signed. Every action logged.

Security here isn't a badge on a footer — it's enforced in code, on every single call.

HMAC-SHA256

Every API request and webhook signed with your merchant secret.

REPLAY PROTECTION

Mandatory Unix timestamp on every request.

2FA (TOTP)

Google Authenticator on the merchant portal.

IP WHITELISTING

Per-account restriction of API caller IPs.

SUB-ACCOUNT RBAC

Users with per-function permissions.

FULL AUDIT TRAIL

Login history and action log for every event.

RATE LIMITING

Per-destination frequency limits.

DUPLICATE SUPPRESSION

Blocks repeat transfers inside a time window.

BLACKLIST / WHITELIST

Block fraudulent accounts yourself, via API.

SLIP VERIFICATION

Checked against real bank records — not OCR.

Reliability

One rail is a single point of failure

Most gateways run one rail — when it goes down, your checkout goes down with it. WealthWave runs 27 live channels with automatic failover.

Single-rail gateway
order rail down ✕
Order fails. Customer leaves. Revenue lost.
WealthWave multi-rail
order ch. 12 ✕ ch. 07 ✓
Automatic retry across channels inside the same order — scored across 9 amount tiers. The customer never notices.

Money never goes missing

Three independent confirmation layers — even if your webhook endpoint is down, the payment still reaches you.

LAYER 1

Signed webhook

Delivered and retried until your server answers HTTP 200.

LAYER 2

Query API

Poll order status any time — PAID is always authoritative.

LAYER 3

Slip upload fallback

Customer submits the slip; we verify it against real bank transaction records.
