Hi, This WooCommerce integration needs to be reliable end to end, especially for checkout, shipping quotes, shipment creation, label generation, and pickup scheduling. I would focus on keeping the flow in sync and preventing duplicate orders or broken rates. My approach would be to validate the API flow first: sandbox testing, shipping quote calculation, shipment creation after payment, ZPL label retrieval, and NetPay gateway testing. I would keep the solution outside WooCommerce core, using clean plugin-level code with solid error handling, retries, and logging for easier troubleshooting. Reliable box/package selection logic would also be a priority since it directly affects live rates. Initial focus: - Review the current WooCommerce flow - Map Paquetexpress API endpoints - Build shipping rate logic - Add shipment and label generation - Test NetPay sandbox flow Could you confirm whether shipment creation should happen only after a successful paid order status, or also for specific manual admin statuses? I’m available to review this via Freelancer chat or video call between 11 AM–8 PM IST. Regards, Ghanu & Samir KESHAV INFOTECH

Hi, I reviewed the project and understand the main requirement: completing a stable WooCommerce integration for Paquetexpress shipping and NetPay payments. I can connect the Paquetexpress REST API for real-time checkout quotations using destination, package weight, dimensions, predefined box sizes, shipment creation, ZPL labels, and pickup scheduling. I’ll configure NetPay as the WooCommerce gateway, then test both integrations in sandbox while handling API errors, retries, duplicate shipment prevention, and logging without modifying WooCommerce core. I’ll keep the implementation clean, production-ready, and responsive throughout testing and delivery. Let’s discuss here now.

@gauravgargcs

Hello, I’ll build everything without touching WooCommerce core, using secure hooks/API integrations and a sandbox-first workflow before production deployment and end-to-end testing. With 10+ years of PHP, WooCommerce, REST API and payment/shipping integration experience, I can deliver a stable, maintainable solution with clear documentation. Let’s chat and review the available Paquetexpress/NetPay documentation and current WooCommerce setup. thank you Regards Gaurav Garg

@extreamcode

Hi ClientFirstName, I can see the hidden risk here: a checkout that looks simple on the surface, but must reliably choose the right box, rate, label, and shipment every time. I’ve built WooCommerce/PHP integrations like this before, and I can complete the Paquetexpress + NetPay flow with clean REST handling, sandbox testing, duplicate-shipment protection, logging, and production-safe code without touching WooCommerce core. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I’ll validate the shipping logic for destination, weight, and dimensions, then wire in shipment creation, ZPL label retrieval, pickup scheduling, and payment-triggered automation so the store stays stable under real orders. I can also review how box selection should behave for edge cases, so the integration feels seamless for both your team and customers. Could you share how you want box selection to behave when multiple package sizes fit the same cart? I can start by reviewing the sandbox flow and mapping the checkout/shipping sequence, then move into testing and hardening. Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

@webperfection123

Hi, Could you please provide access to the existing WooCommerce setup and the Paquetexpress documentation? I can help integrate the REST API with WooCommerce for real-time shipping quotations and automate shipment creation post-payment. With over 12+ years of experience in PHP and WooCommerce, I’ve successfully completed similar integrations, ensuring a seamless user experience. I’ll prioritize proper error handling, logging, and sandbox testing before going live. Additionally, I can set up NetPay as a payment gateway and create a stable solution without altering WooCommerce core files. Let’s ensure everything is well-configured for package sizes and scheduling too. Please see our portfolio on this link : https://www.freelancer.com/u/webperfection123 Looking forward to working together to finalize this integration! Best Regards, Priyanka

@raphaelokekeze

Hi, You need to connect the Paquetexpress REST API for live shipping rates and automated label generation, alongside your NetPay gateway configuration. I will start by reviewing your Postman collection against the active WooCommerce hooks to map out the payload structures for weight, dimensions, and box-packing logic. Writing clean WooCommerce integrations means hooking properly into the cart and checkout without ever touching core files. My plan is to build out the REST communication, set up transient caching for rate quotes to keep checkout fast, implement idempotency keys to prevent duplicate shipments, and write comprehensive error logging before moving to sandbox testing. My bid of $112 covers the complete end-to-end build, gateway setup, and rigorous sandbox testing for both APIs, delivered in 1 day. Send over your sandbox credentials and Postman collection so I can jump right into the API mapping.

@anirudhat

Two things will decide whether this integration is stable in production, and both are easy to get wrong. First, the checkout quote: WooCommerce calls `calculate_shipping()` repeatedly — on every address change and often several times per page load — so a live API call on each invocation makes checkout crawl and burns your quota. I'd build it as a proper `WC_Shipping_Method` with results cached against a hash of the package contents plus destination postal code, a short HTTP timeout, and a configured fallback rate if Paquetexpress is slow or down. That fallback matters more than it sounds: when a carrier API hangs, the shipping section renders empty and every customer is silently blocked from paying. Second, duplicate shipment prevention needs more than a flag check. If the guía request succeeds but the response is lost to a timeout, a naive retry creates a second shipment you get billed for. So every request carries our own reference, and before retrying I query by that reference to see whether the shipment already exists — combined with an atomic order-level lock so two concurrent triggers can't both proceed, and the tracking number written to the order the moment it's returned. Generation fires from a single guarded hook on payment confirmation, since gateway webhooks do fire twice. On the box logic: predefined package sizes make this a bin-packing problem, not a weight sum. I'd implement first-fit-decreasing packing with rotation, and quote on the greater of actual versus volumetric weight (L×W×H/5000), because quoting on real weight alone loses money on every bulky order. I'd also add an admin report flagging products missing weight or dimensions, plus sane defaults, since a single incomplete product otherwise breaks quoting sitewide. Everything ships as a standalone plugin — no core modifications — declared HPOS-compatible and using CRUD methods rather than direct post meta, since WooCommerce 8.2+ defaults to the new order tables and direct meta access silently fails there. ZPL labels get stored on the order rather than re-fetched, with a download action and bulk printing, and I'd add a PNG preview so staff can eyeball a label before printing. Logging goes through WC_Logger under its own source so it appears in WooCommerce → Status → Logs, with request and response bodies plus a correlation ID, and failures also written as order notes so your team sees them where they work. NetPay I'd verify end to end in sandbox including 3DS, confirming that shipment creation only ever triggers after a genuinely confirmed payment. One thing to confirm early: whether you need Carta Porte data handled on your side or Paquetexpress covers it, since that affects what we send at shipment creation. Send me the sandbox credentials and Postman collection — production keys you set yourself at go-live — and I can start immediately with the quoting method and packing logic.

@seefattechnologi

SURE---------------I will do it -------------WooCommerce shipping integrations like Paquetexpress require careful handling of package dimensions, live rates, shipment creation, labels, and duplicate prevention. I can complete the integration using PHP and REST APIs without modifying WooCommerce core. I will handle Paquetexpress rates, box selection, shipment creation, ZPL labels, pickup scheduling, NetPay, sandbox testing, retries, and logging. One important question: is the existing WooCommerce store already calculating package weight and dimensions correctly at checkout, or should that logic also be implemented? Please ping me to get started and get outstanding results. Thanks!!!

@SBITServices

Hi, I understand you already have the WooCommerce store running and need the Paquetexpress and NetPay integrations completed and made production-ready. I can handle the full Paquetexpress flow: real-time checkout rates based on destination, weight and dimensions, predefined package selection, shipment creation after successful payment, ZPL label retrieval, and pickup scheduling. I’ll also integrate and test NetPay, with proper error handling, retries, logging and duplicate-shipment protection. I have 10+ years of experience with WordPress, WooCommerce, PHP and REST API integrations. I’ll work with the provided sandbox credentials and documentation first, test the complete order-to-shipment flow, and then prepare it for production without modifying WooCommerce core. I can start immediately. Thank you Regards, Sai

The goal is to provide real-time shipping quotes at checkout, manage package selection, and automate the shipment process after payment. I would approach this by carefully implementing the API calls to ensure accurate data handling for weight, dimensions, and package sizes. My experience with WooCommerce and PHP will help me smoothly integrate the shipping and payment functionalities without altering the core framework. I’m well-versed in handling API errors and ensuring reliable processing, so your integration will be stable and user-friendly. Testing in the provided sandbox will ensure everything works seamlessly before going live. Best regards, Saba Ehsan

@WebTechDesignBG

Hello, I see you're looking to complete a WooCommerce integration with the Paquetexpress REST API. This involves setting up real-time shipping quotes, handling package sizes, generating shipments post-payment, and scheduling pickups, all while ensuring a smooth user experience. With 7+ years of experience in PHP, WooCommerce, and API integrations, I’m confident I can help you achieve a stable and production-ready solution. I’d begin by analyzing your current setup and then carefully implement the API integration, ensuring all functionalities like error handling and label generation are seamlessly integrated. You can check out my past work at https://pixoriq.com.

Best regards, Ivan Mandinski

@CANWS

Hi, I can complete this directly on your existing WooCommerce store without touching WooCommerce core. The important part here is making the full order flow reliable: NetPay payment → shipping quotation → Paquetexpress shipment → ZPL label → pickup scheduling, with proper error handling and no duplicate shipments. I’ll also handle the package/box selection logic, real-time checkout rates, API retries, logging and sandbox testing before production. I have strong experience with WooCommerce, PHP and REST API integrations, so I can work with the existing store and available Paquetexpress/NetPay documentation and credentials. The goal is a stable integration that works automatically once an order is paid. Ready to review the current setup and start. Thanks

@crtvecode

I see you're looking to integrate the Paquetexpress REST API with your WooCommerce store, which involves real-time shipping quotes and generating ZPL shipping labels. Those key challenges here include handling API errors, implementing retries, and preventing duplicate shipments, all while making sure no changes to the WooCommerce core. So, I can tackle this by first setting up the integration in a way that handles errors gracefully and logs activities for troubleshooting, I’ll make sure the shipping quotes are accurate based on your package dimensions and weights, and I'll configure the pickup scheduling and NetPay integration as specified. I can go ahead and have this ready for you to test first—only award the project once you’re happy with it, so there’s no risk on your end. My bid for this work is $62, and I’m ready to start immediately, whenever you are ready to move forward with it. Rajavel WooCommerce, PHP, REST API Specialist

Your Paquetexpress integration will fail in production if you don't handle rate-limiting on the shipping quote API during checkout spikes. Most developers miss this and customers see blank shipping options at peak traffic. Quick questions - are you handling webhook retries if NetPay sends duplicate payment confirmations? And what's your fallback if Paquetexpress label generation times out during order fulfillment? Here is the architectural approach: - PHP/WOOCOMMERCE: Build custom plugin that hooks into checkout without touching core, implements queue system for label generation to prevent timeout failures during high-volume order processing. - PAQUETEXPRESS REST API: Design retry logic with exponential backoff for shipping quotes, implement idempotency keys to prevent duplicate shipments if customer refreshes confirmation page. - NETPAY PAYMENT GATEWAY: Create webhook handler with signature verification, transaction logging table to catch duplicate IPNs and prevent double-charging edge cases. I've built similar carrier integrations for 2 logistics platforms that process 500+ daily shipments without dropping labels. Let's schedule a 20-minute call to review your sandbox API responses before I architect the error handling.
