Coinsnap

  • Name: Coinsnap
  • URL: https://www.coinsnap.io/
  • Category: bitcoin merchant-payments control plane / hosted checkout and webhook infrastructure / plugin-and-POS integration stack
  • Tags: bitcoin-ecosystem
  • Summary: Coinsnap is hosted Bitcoin merchant plumbing: invoice creation, hosted checkout, webhook-confirmed settlement, persistent pay links, POS and wallet surfaces, and a broad plugin footprint. Useful merchant glue, not a payments anchor.
  • What it does:
    • Lets merchants create hosted Bitcoin invoices through an API and redirect customers to a Coinsnap checkout page with QR rendering and realtime status
    • Supports both Lightning invoices and on-chain Bitcoin addresses through the same invoice flow
    • Uses signed webhook events such as Settled, Processing, Expired, and Invalid for server-side payment confirmation and reconciliation
    • Offers persistent pay links that can survive multiple underlying Bitcoin invoice expirations and fit email, PDF, ERP, and account-area billing flows
    • Provides a self-custodial Coinsnap Wallet mobile app with integrated POS support for in-person Bitcoin acceptance
    • Maintains official plugins for many ecommerce, CMS, donation, and form systems, plus examples for custom Node.js and PHP integrations
  • Key claims:
    • The homepage says merchants can receive funds directly into their own Bitcoin wallet or bank account, describes Coinsnap as a self-custody Bitcoin provider, and emphasizes Lightning plus on-chain support for online, website, and on-site payments
    • The developer docs frame the product as an end-to-end Bitcoin and Lightning integration where the merchant creates an invoice, shows a QR code through hosted checkout, and confirms settlement via webhooks rather than browser redirects
    • The quickstart response model includes both lightningInvoice and onchainAddress, which is a strong sign that Coinsnap is normalizing multiple Bitcoin payment rails behind one merchant API
    • The webhook docs explicitly say only the webhook is reliable, require HMAC verification via X-Coinsnap-Sig, and document operational states such as Processing, Settled, Expired, Underpaid, Overpaid, and PaidAfterExpiration
    • The pay-links docs distinguish between a long-lived merchant-facing pay link and short-lived generated Bitcoin invoices, which makes the product useful for async invoicing and B2B payment collection rather than only cart checkout
    • The plugins docs and GitHub organization show an unusually broad first-party plugin footprint across WooCommerce, Shopify-by-request, Shopware, Magento, PrestaShop, OpenCart, Wix, Drupal, pretix, donation tools, paywall flows, and more
    • The public GitHub organization tagline calls Coinsnap a Lightning payment provider and its repo list centers on storefront/CMS integrations plus a coinsnap-core package, which supports viewing it as infrastructure rather than only a merchant app
  • Whitepaper: No canonical standalone Coinsnap whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site, developer docs, webhook/payment-link docs, and the public GitHub organization; see ../whitepapers/coinsnap-primary-sources-2026-05-02.md.

Internal linkages

Control surface

  • Power sits in hosted invoice issuance, webhook truth, plugin coverage, pay-link behavior, wallet and payout defaults, and how much merchant workflow Coinsnap keeps inside its own dashboard.

  • The interesting part is the packaged checkout and integration surface. The rest is ordinary processor middleware.
