Build a production-ready browser automation tool for the Yodobashi online store that completes the entire checkout flow through a clean, fully documented API. The core objective is to reach the order-confirmation page—reliably and at speed—so downstream systems can act on the result in real time. Key workflow • Accept an item URL or product-code via my API, log in through a rotating proxy pool with one of many stored accounts, add the item to cart, apply any available coupons, and finish payment. • On success—or failure—immediately post a JSON payload to a specified Discord webhook so I can monitor every attempt. • Everything must run headless; Playwright or Puppeteer preferred for speed, but I’m open to other Chromium-based solutions if you can prove lower latency. Must-have features • Multi-account login automation routed through proxies • Automated purchase and payment confirmation • Discord webhook reporting (success / fail, order ID, used account) • Full API surface (start job, job status, cancel, logs) with token authentication • Optimised execution time; benchmark your solution and share metrics Acceptance criteria 1. Completing checkout on a test SKU under real-world load in ≤ 10 seconds average. 2. Handling at least 50 parallel checkouts without CAPTCHA blocks or proxy leaks. 3. API and codebase delivered with README, environment variables template, and sample cURL calls. 4. Error handling that categorises issues (out of stock, payment decline, proxy timeout, etc.) in webhook responses. When you reply, focus on relevant experience building high-speed e-commerce bots, dealing with anti-bot measures, and integrating webhooks or REST APIs. Links or brief descriptions of similar projects are enough—I’ll follow up for deeper details after review.

Hey, I will build your Yodobashi checkout bot — headless Playwright, multi-account login through rotating proxies, full API with token auth, and Discord webhook reporting for every attempt. For anti-detection, I will fingerprint-randomize each browser context and stagger request timing to avoid pattern-based blocks — critical for sustaining 50 parallel sessions without triggering CAPTCHAs. Questions: 1) Which payment method do the stored accounts use — credit card, or a Yodobashi-specific option? 2) Do you already have a proxy provider, or should I recommend one optimized for Japanese IP ranges? This bid is an initial estimate — I will confirm the final cost and timeline once we have walked through the complete requirements together. Looking forward to your response. Best regards, Kamran

Hi there, Yodobashi’s checkout flow, proxy routing, and webhook reporting need to stay stable under load, not just “work once.” I’ve spent the last 4 years solving exactly this type of problem: high-speed browser automation, multi-account login flows, and API-first bot orchestration. I’ve delivered a Playwright checkout system with queue control and retry telemetry, and built a Chromium-based purchase flow that reduced failure classifications from vague timeouts to clean, actionable states. The real risk here is anti-bot friction breaking at scale: proxy leaks, session reuse mistakes, and slow handoffs between cart, payment, and confirmation. I’ll build the flow headless with isolated sessions, token-authenticated job control, structured logging, and webhook posts for success, fail, and order IDs. I’ll also benchmark the critical path and keep the codebase documented so your downstream systems can react instantly. Best regards, John allen

Hi, as a Web Developer specializing in advanced browser automation and high-speed API architectures, I can build a production-ready checkout bot for Yodobashi using Playwright/Puppeteer. I will design a secure, token-authenticated REST API layer that accepts product parameters, routes headless browser instances through your rotating proxy pool, and handles concurrent multi-account checkouts within your 10-second threshold. The automation engine will integrate robust anti-fingerprinting measures to prevent CAPTCHA blocks, alongside an absolute error-handling matrix that categorizes declines or timeouts. Finally, the system will immediately dispatch clean JSON payloads to your Discord webhooks for real-time monitoring and include a fully documented configuration template. Quick question: Does the current Yodobashi checkout flow enforce intensive Javascript-based anti-bot layers (like Cloudflare/Akamai) at the final payment submission, or are we primarily optimizing for proxy concurrency and request latency? Let's build this system!

Hi there, I see you're looking to build a reliable browser automation tool for Yodobashi's checkout process. The goal is to create a seamless experience that can handle multiple accounts and proxies while providing real-time updates via a Discord webhook. I can help with that. With 4+ years of experience in developing high-speed e-commerce bots, I understand the challenges of navigating anti-bot measures and ensuring smooth transactions. My approach would involve using Playwright or Puppeteer for efficient automation, ensuring that we can complete the checkout flow within the required time frame while managing multiple parallel sessions without interruptions. I’ll ensure that the API is well-documented, making it easy for you to integrate and monitor. One question I have is about the types of products you'll be targeting. Are there specific categories or SKUs that you expect to focus on for testing the checkout process? Best regards, Arslan Shahid

Two numbers anchor this: ≤10s average checkout on a test SKU, and 50 parallel runs with no CAPTCHA blocks or proxy leaks. The hard part isn't the Yodobashi flow itself, it's keeping latency low while the proxy pool and account rotation stay invisible to anti-bot. Day one I'd ship a single working headless run (login through proxy, add to cart, coupon, pay, confirmation) so we benchmark real latency before scaling. How I'd build it: 1. Playwright headless workers behind a job queue, each pinned to a rotating proxy and a stored account, with browser-context reuse to cut cold-start time. 2. REST API with token auth: start job, status, cancel, logs. Every attempt posts JSON to your Discord webhook with success/fail, order ID, and account used. 3. Categorised error handling (out of stock, payment decline, proxy timeout) surfaced in both the API and the webhook payload. Closest proof: I built the API and webhook layer for an enterprise SaaS handling concurrent jobs with Stripe payment confirmation, so payment-state correctness under load is familiar ground. Done = test SKU reaches order-confirmation in ≤10s average, 50 parallel jobs clean, delivered with README, .env template, and sample cURL calls. At $162 / 7 days, I'd scope milestone one as the single-run benchmark. Do you want concurrency tuning targeting exactly 50, or headroom built in for more? Waqar
