After Quickstart, every component here should correspond to something you touched. This page freezes the vocabulary—browser, your backend, Unseen gateway, Solana—used in later sections (Environments, Lifecycle, SDK pages).

​
Components

LayerRole
Browser (@unseen_fi/ui)Checkout modal, wallet deeplinks/QR, verification polling. May call your backend to create sessions or the public verify endpoint when given paymentToken.
Your backendHolds the API key; creates/cancels/lists payments; fulfills orders; verifies webhooks. Uses @unseen_fi/sdk.
Unseen APIPayment sessions, merchant profile, verify endpoints, webhook delivery.
SolanaOn-chain settlement; verify checks transaction state.

​
Security boundaries

  • Never expose usk_live_* in client bundles. Use createPaymentSession from the UI to hit your own API.
  • Webhook bodies must be verified with HMAC before trusting payment.confirmed-style events (@unseen_fi/sdk → unseen.webhooks.verify).

​
UI package API paths

The UI uses your provider baseUrl and appends paths such as:
  • POST /api/v1/payments (when creating from the browser with apiKey)
  • POST /api/v1/payments/:id/verify (merchant verify, Bearer)
  • POST /api/public/payments/:id/verify (checkout verify, x-unseen-payment-token)
