1. Generate and retain a private random buyer bearer capability, or sign in with a wallet.
2. Create a quote with variant_id, quantity, a delivery address and a unique Idempotency-Key.
3. Review subtotal, shipping, tax, total and expires_at. Restrict purchases to the buyer's authorized budget.
4. Card checkout returns a hosted payment URL for a human. For autonomous x402 payment, request provider=x402, inspect the 402 challenge, sign its exact USDC amount on Base and retry with Payment-Signature.
5. Poll the same order. An unknown outcome is not a failed payment. Never switch payment methods or create another order to recover a pending payment.

Wallet login is optional, uses an expiring single-use SIWE challenge, and does not authorize payment. EOA sign-in only. Wallet sessions last eight hours. Keep tokens and delivery details private. Guest orders stay with their original buyer capability.

Printify production requires the merchant's manual approval. Paid, submitted, in production and shipped are distinct states. Do not tell a buyer an order shipped until the order reports fulfillment. Shipping is limited to the contiguous United States.
