Common across all partners¶

Every Via One partner integration follows the same security + idempotency standards:

Authentication: JWT (HS256, 1-hour) from POST /api/dislogin or POST /api/distributor/login
Idempotency: Idempotency-Key HTTP header OR dist_transid body field — required to prevent duplicate processing
Webhooks: HMAC-SHA256 signed (X-ViaOne-Signature: sha256=<hex>)
Rate limiting: per-distributor based on JWT customer_id claim

Partners signing up should expect to receive:

Customer ID and secret_key (for /dislogin)
API key (for x-api-key auth, optional)
Webhook signing secret (if subscribing to events)
IP whitelist setup (optional, on by default for production tier)
Initial wallet balances (USD, optionally MXN if professional tier)
