CryptoProcessing by CoinsPaid

  • Name: CryptoProcessing by CoinsPaid
  • URL: https://docs.cryptoprocessing.com/
  • Category: merchant crypto-payments control plane / exchange-and-settlement infrastructure / compliance-heavy invoice-deposit-withdrawal backend
  • Summary: CryptoProcessing by CoinsPaid is a merchant-payments control plane. The interesting part is not the invoice page; it is the operator backend around deposits, exchange, withdrawals, callbacks, user roles, balance limits, and compliance collection. Read it as merchant plumbing with settlement and policy knobs, not as a simple crypto checkout button.
  • What it does:
    • Lets merchants create hosted crypto invoices for B2B or B2C customers, returning a payment URL that the merchant can pass through to the payer
    • Supports reusable customer deposit addresses via /v2/addresses/take, with optional automatic conversion into a target currency for merchant balances
    • Supports outbound crypto withdrawals, including withdrawal-with-exchange flows where funds stored in fiat balances can be converted on the fly into the payout asset
    • Exposes asynchronous callback-driven workflows for deposits, invoices, exchanges, and withdrawals, including retry logic and signed webhook verification
    • Uses HMAC-SHA512 request signing with X-Processing-Key and X-Processing-Signature for both API authentication and callback validation
    • Offers merchant-operating features beyond raw API endpoints, including user roles, withdrawal limits, cold-address controls, mass payouts, fiat-balance top-ups/withdrawals, and plugin integrations for common commerce platforms
    • Bakes in regulated data-collection and compliance steps in the invoice flow, with docs explicitly noting MiCA-related payer-data prompts for natural persons and legal entities
  • Key claims:
    • The docs homepage says CryptoProcessing is a crypto payment gateway that lets businesses accept 20+ popular cryptocurrencies, exchange crypto into traditional currencies, and withdraw to bank accounts
    • The invoice docs describe three invoice modes, including timed and pre-selected-currency variants, and say hosted invoice flows collect customer identity details in line with MiCA requirements
    • The deposit docs show that CryptoProcessing generates long-lived customer deposit addresses, supports optional automatic conversion on receipt, and differentiates between invoices and deposits as distinct merchant workflows
    • The withdrawal docs describe a “withdrawal with exchange” pattern where merchant fiat balances are converted into crypto before funds are sent to the user’s wallet, indicating the platform is a settlement backend rather than a receive-only gateway
    • The callback docs say CryptoProcessing can instantly confirm some deposits internally before onchain confirmation, retries failed callback deliveries up to 12 times on a defined schedule, and expects merchants to de-duplicate callbacks by transaction ID
    • The authentication docs specify exact-body HMAC-SHA512 signing and caution that even field-order or whitespace drift can break request validation, which is a notable operational detail for integrators
    • The docs index also exposes plugin integrations for WordPress, Magento, Joomla, OpenCart, PrestaShop, and Drupal, reinforcing that the product is meant to sit directly in merchant operations rather than only serve custom fintech teams
  • Whitepaper: No canonical standalone CryptoProcessing by CoinsPaid whitepaper or litepaper surfaced in this pass. The official docs corpus was the clearest current source of truth, while the main marketing site returned a Cloudflare block during retrieval; see ../whitepapers/cryptoprocessing-primary-sources-2026-05-03.md.
