Overview

Official miaPOS payment gateway for WooCommerce, distributed as open source on GitHub: finergy-tech/mia-pay-gateway-for-woocommerce. The plugin implements the E-comm API protocol end-to-end — merchants install, paste credentials, accept instant payments alongside existing methods.

Install

  1. Grab the latest release from the GitHub releases page (or clone the repo).
  2. WordPress admin → Plugins → Add New → Upload Plugin → choose the .zip.
  3. Activate. The gateway appears under WooCommerce → Settings → Payments.

Configure

  1. Open the plugin settings page.
  2. Paste your merchantId, secretKey, terminalId (issued by miaPOS during onboarding).
  3. Set ecommBaseUrl — https://ecomm-test.miapos.md for sandbox, https://ecomm.miapos.md for production.
  4. Choose language (en, ro, ru) and paymentType (qr or rtp).
  5. Save and run a test transaction.

Callbacks

The plugin handles all callback verification automatically. miaPOS POSTs the signed result to the merchant-side callback URL; the plugin verifies the RSA signature using the public key from /ecomm/api/v1/public-key and updates the order status. Full algorithm in the Signature Verification Guide.
