I run DAWGLOGZ out of Chicago and need an expert who already speaks Amazon Selling Partner API fluently. Your job is to connect directly to our Seller Central account, read every Buyer-Seller Message, recognise which charity option (A–E) the customer selected, and log that choice alongside the matching order in a small database you set up. Each month the system must also pull Sales Tax and Order data with the Reports API, crunch the numbers, and output exact donation totals per charity. As soon as a choice is detected, the buyer should automatically receive a Donation Confirmation reply through the Messaging API—nothing else, just that one acknowledgement. I prefer a lightweight desktop dashboard so I can view real-time charity counts, individual orders, and month-to-date totals without opening a browser. Whether you build it with Electron, Qt, or another framework is up to you as long as it installs cleanly on Windows and shows the data in a clear, filterable interface. Core deliverables: • SP-API authentication via LWA/OAuth and role setup • Message parsing, charity code detection, order-matching logic • Database schema and persistence layer • Monthly donation calculation using Reports API pulls • Automated Donation Confirmation reply workflow • Desktop dashboard with live metrics and basic export to CSV Acceptance will be based on: 1. End-to-end test in my live Seller Central account (sandbox first, then production) 2. Accurate logging and donation totals across at least one full day of orders 3. Successful delivery of the Donation Confirmation message within 15 minutes of receipt 4. Smooth desktop installer and clear README Because our data is sensitive, I can only work with someone physically located in Chicago, Illinois for occasional in-person sessions. If you have verifiable SP-API projects under your belt and can start soon, let’s talk.

Hi, I’ve built automation around Amazon SP-API messaging and reporting workflows with reliable order matching. You need a Windows desktop app that authenticates to SP-API, parses Buyer-Seller messages to detect charity A-E, logs choices to a small database, and sends a single Donation Confirmation reply via the Messaging API within 15 minutes. I deliver end-to-end SP-API tests in sandbox then production with accurate daily totals and clean installers.

Hi — Elias here from Miami. I understand you’re seeking an expert to navigate the complexities of the Amazon Selling Partner API for DAWGLOGZ. The goal seems to be automating processes to streamline operations and improve efficiency. What usually matters most here is ensuring the integration is robust and scalable. A common issue in systems like this is managing API limits while maintaining performance. The tricky part is ensuring data flows seamlessly while handling potential errors gracefully. My approach would involve a structured architecture that emphasizes stability and maintainability. I'd focus on clear API integration patterns, efficient database interactions, and a user-friendly desktop application interface using Qt. Proper error handling and logging will be key to future-proofing the system. I've developed similar automation solutions and integrated various APIs, giving me insight into potential pitfalls and best practices for reliability. A few questions to better understand the scope: Q1 – What specific functionalities do you want to automate with the SP-API? Q2 – Are there existing systems or databases that need to be integrated? Q3 – What are your expectations regarding scaling and future feature expansions? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hi, I reviewed the project and understand that DAWGLOGZ needs a desktop system connecting to Amazon SP-API to read Buyer-Seller Messages, identify charity choices, and match them with orders. I’ll implement LWA/OAuth authentication, message parsing, charity code detection, order matching, database persistence, Reports API calculations, and the Donation Confirmation workflow through the Messaging API. The lightweight dashboard will show live charity counts, orders, month-to-date totals, filtering, and CSV export, with sandbox-to-production testing and a Windows installer. I’ll keep the application secure, responsive, clearly documented, and easy to manage through a clean README and reliable delivery within the required timing. Let’s discuss here now.

Hello!, This is James from Hollywood... I read your Amazon SP-API Desktop Automation post carefully, and the main pain point is not just “connecting to Amazon” but building a desktop tool that stays stable, handles auth correctly, survives API edge cases, and gives your team a workflow that’s actually usable every day. That’s where I can help. My approach: 1) map the exact DAWGLOGZ workflow and required SP-API endpoints 2) design the desktop flow for login, token refresh, requests, logs, and retries 3) build the backend layer with solid error handling, AWS integration, and database storage 4) test it against real scenarios so it’s reliable, not just a demo I’ve built automation and data tools where the details mattered: pagination, rate limits, auth refresh, sync failures, audit logs, and keeping the UI simple for non-technical users. I’m very comfortable with Python, PHP, Qt, AWS, API integration, and database design, so I can keep both the engineering and usability side strong. Relevant work: - inventory sync desktop tool for a regional e-commerce brand - order management dashboard for a 3PL workflow - supplier automation app for a consumer goods seller Quick questions: 1) Which SP-API actions do you need first: orders, inventory, shipments, reports, or all? 2) Should the app be Windows-only, or cross-platform with Qt? 3) Do you already have AWS and Amazon developer credentials set up? If you want, I can outline the fastest path to a first working version and the

Hi, I’d build this around Amazon SP-API with a clear separation between message ingestion, charity-code detection, order matching, donation calculations, and the desktop dashboard. The workflow would authenticate through LWA/OAuth, capture Buyer-Seller Messages, identify selections A–E, match them to the correct order, persist the result, and trigger exactly one Donation Confirmation response. For the reporting side, I’d schedule the Reports API pulls for sales tax and order data, calculate month-to-date totals per charity, and expose those figures through a filterable desktop interface with CSV export. I’d also include retry/error handling, audit-friendly records, and sandbox-to-production testing before live acceptance. The Chicago-only in-person requirement is the one constraint I’d need to confirm before proceeding. Best, Ivane

The hard part here isn’t pulling SP‑API data - it’s keeping Buyer‑Seller Messages, charity codes and order records perfectly aligned in real time. SP‑API often delivers messages and order updates on slightly different schedules, so the matching logic has to be deterministic even when Amazon’s payloads arrive out of order. The 15‑minute confirmation window also means the message‑parsing loop can’t rely on slow polling or fragile heuristics. I’ve built similar SP‑API automations where the key was treating each message as an event: parse the charity code, resolve the order via the Orders or Reports API, then write a single atomic record to the local database. My approach would be to start by defining the schema for orders, messages and charity selections, then build a small ingestion layer that normalizes SP‑API responses before anything touches the dashboard. For the desktop app, I’d keep it lightweight — a local process that reads from the database, streams live counts, and triggers the confirmation reply workflow as soon as a match is logged. One thing I’d watch closely is Reports API throttling. Monthly tax pulls can be slow, so the donation‑calculation step should run asynchronously and store snapshots to avoid blocking the dashboard. A few quick questions: – Should the dashboard store historical months or only current totals? – Are you already set up with SP‑API roles and LWA credentials, or should I handle the initial configuration?

I’ve worked hands-on with Amazon’s Selling Partner API before, including automating message parsing and order data extraction for a similar e-commerce client. For your project, I’ll start by setting up secure LWA/OAuth authentication and carefully linking each Buyer-Seller Message to orders while identifying the charity codes you use. I’ll design a simple database that logs everything cleanly and ensures smooth monthly pulls of sales tax and order data from the Reports API. To meet your timeline and reliability needs, I suggest a quick sandbox test of the messaging workflow including the Donation Confirmation reply within 15 minutes, then move to live Seller Central. For the dashboard, Electron is a good lightweight choice that can show real-time stats while filtering by charity or date and exporting data as CSV. Do you have any preferred charity code formats or keywords I should watch for in the messages? Also, should the donation totals be shown in exact dollar amounts or percentages from the sales tax data? I’m close enough to Chicago for in-person sessions and can start setting up the integration immediately. Let me know how you’d like to proceed.

I’m young, a fast learner, available 24/7, and can accommodate the required Chicago in-person sessions. Get the demo first before you pay. Two quick questions: Do buyers select A–E from a fixed message template or free-text replies? Also, should donation totals be calculated from item subtotal only, or include/exclude tax, shipping, and refunds? Let’s chat and discuss these answers so I can start properly. Kind regards, Haroon Z

I can build DAWGLOGZ’s SP-API desktop automation from sandbox through production, with careful handling of sensitive Seller Central data. The solution will use Amazon Web Services and PHP to implement secure LWA/OAuth authentication, role configuration, Buyer-Seller Message retrieval, charity-code recognition, and reliable order matching. I’ll design the Software Architecture around a maintainable persistence layer so every selection, order, response status, and audit event is traceable. Using the Reports API, the system will calculate monthly sales-tax and order-based donation totals for charities A-E. The Messaging API workflow will send only the required Donation Confirmation reply, with retry and status handling designed to meet the 15-minute delivery target. I’ll also deliver a lightweight Windows desktop dashboard with real-time counts, order-level filtering, month-to-date totals, CSV export, a clean installer, and a clear README. Testing will proceed in the sandbox before a controlled live-account validation across a full day of orders. I’m ready to begin with the SP-API role/access review and a focused end-to-end implementation plan.
