PrintaRex Integration for WooCommerce

PrintaRex Integration for WooCommerce connects your store to the PrintaRex fulfillment network, providing accurate per-city, per-item shipping rates at checkout.

Key Features:

• Real-time rates – Shipping costs are calculated based on the customer’s exact city, not just country or state.
• Per-item pricing – Each product is priced individually based on its provider’s shipping zones.
• Easy setup – After entering the API URL, the plugin auto-configures by detecting your store’s PrintaRex connection.
• Mixed cart support – Non-PrintaRex items are silently ignored; they use your existing WooCommerce shipping zones.
• Fallback rate – If the PrintaRex API is temporarily unavailable, a configurable flat rate is used.
• Caching – Rates are cached for 5 minutes (configurable) to minimize API calls.

Supported Countries:

The plugin provides per-city zone rates for all countries in the PrintaRex network, including UAE and Egypt – even for countries where WooCommerce has no built-in state/province definitions.

External Services

This plugin connects to the PrintaRex API (configured via the API URL setting) to provide real-time shipping rates. Requests are made in the following scenarios:

• Plugin activation & admin auto-configuration — A GET request is sent to {api_url}/carrier-service/woocommerce/lookup with your site domain to retrieve your store connection ID. This runs on activation and is retried periodically from the WordPress admin if the connection ID is missing (with a 1-hour backoff between attempts). The WooCommerce consumer secret is configured in the shipping method settings and signs rate requests.
• Checkout rate calculation — A POST request is sent to {api_url}/carrier-service/woocommerce/{connectionId}/rates each time a customer enters their shipping address at checkout.

Data transmitted to PrintaRex:

• Your store’s domain (during activation lookup)
• Customer destination city and country code (during rate calculation)
• Cart item WooCommerce product/variation IDs and quantities
• Store currency code

No personal customer data (name, email, phone, payment details, IP address) is transmitted.
