Zuuppa Processing — Documentation

Accept Solana payments without touching a private key. Zuuppa Processing gives every order its own deposit address, detects the payment on-chain, sweeps the funds to your wallet, handles refunds automatically, and notifies your backend — all over a small HTTP API.

It works for native SOL and any SPL token (including Token-2022).

You never run a server, hold a seed, or touch Solana RPC. You sign up, set your sweep destination, grab an API key, and make HTTP calls.

How it works in 30 seconds

1. Your backend  ──POST /intents──▶  Zuuppa Processing   → returns a deposit address
2. Your frontend shows that address (+ QR) to the payer
3. Payer sends SOL / USDC / etc. to the address
4. We detect it and sweep it to YOUR wallet (minus an optional platform fee)
5. Your backend is notified (webhook) or polls  GET /status  → "swept", exact amounts

Everything on-chain — key custody, detection, sweeping, refunds — is handled for you. You only ever call the HTTP API with your API key.

Get set up

1. Getting started — create your account, set your sweep destination and webhook, and get an API key. Start here.
2. Concepts — payment intents, assets, base units, the settlement lifecycle, and statuses. Read before integrating.
3. API reference — every endpoint, field, and error.
4. Integration guide — a step-by-step checkout flow with example code.
5. Webhooks — get pushed events instead of polling.

The two ways to talk to us

• Dashboard (this website): sign in, configure your account, manage API keys, and watch payments. Sign-in is passwordless — we email or text you a code.
• Payments API: your backend calls it with an API key (Authorization: Bearer sk_live_...). This is what powers checkout.
