​
Prerequisites

  • Plugin installed and activated
  • Settlement wallet configured in Merchant Admin
  • WooCommerce connection key from Dashboard → Integrations → WooCommerce

​
Steps

  1. Open WooCommerce → Settings → Payments → Meum Crypto Payments
  2. Paste the connection key from Merchant Admin
  3. Click Connect
  4. On success, the plugin stores:
    • Dedicated API key
    • Webhook secret
    • Integration ID
  5. Enable the gateway checkbox
  6. Save settings

​
Advanced settings

  • Platform API URL: default https://api.meum.io. Change only when Meum support provides a different base URL for your environment.
On Growth and Business plans, configure whether the platform fee is paid by the merchant or customer under Dashboard → Stores → [Store] → Settings → Checkout. See Checkout fees.

​
Shop currency

WooCommerce sends the store shop currency on each invoice. That currency must be allowed in Meum merchant invoice fiat settings. Otherwise checkout fails with CURRENCY_NOT_ALLOWED (HTTP 403). Fix: allow the shop currency in Merchant Admin, or change WooCommerce → Settings → General → Currency to a currency Meum already allows. See Common API errors.

​
Expected result

Gateway shows “Connected” status. Checkout displays “Pay with Crypto”.
