AI Chatbot & Python Developer (NLP/LLM) for E-commerce & No-Code Workflow Integration We are looking for an experienced Python / Machine Learning Engineer to design and build an AI-powered conversational chatbot for our e-commerce store. The backend must be built in Python (FastAPI), but it must be built with external integrations in mind allowing no-code automation platforms (like [login to view URL], n8n, or Zapier) to trigger it and consume its outputs. Key Responsibilities: - Conversational AI & NLP: Build a natural, accurate conversational chatbot in Python using modern LLM frameworks (OpenAI API, LangChain, or similar). - E-Commerce Utility: Integrate store product data (via CSV/API) to answer customer queries about product specs, pricing, and live availability. - Support Automation: Handle order tracking/status lookups and standard e-commerce FAQs (shipping, returns, policies). - API & No-Code Gateway: Deploy a clean FastAPI endpoint that acts as a bridge. It must easily accept incoming requests from webhooks/no-code platforms and send structured JSON payloads back. - Conversation Design & Hand-offs: Implement fallback logic, greetings, and structured handoff payloads (e.g., sending a notification payload when a human agent needs to step in). What We Need Delivered 1. Fully functioning Python chatbot code accessible via a FastAPI endpoint. 2. Webhooks & No-Code Integration: Clear documentation on how to hook the FastAPI endpoint into visual workflow builders like [login to view URL], n8n, or Zapier. 3. Clear documentation on how product data is ingested/updated. 4. Clean, simple setup and integration instructions.

Hi, I understand you need a Python FastAPI chatbot that not only answers product, pricing, availability, order tracking, and FAQ queries, but also exposes webhook-ready endpoints that integrate cleanly with [login to view URL], n8n, and Zapier while supporting structured AI-to-human handoffs. I'll build the backend using Python, FastAPI, OpenAI GPT-4.1, LangChain, and PostgreSQL, with product data synchronized from CSV or your store API for accurate responses. The most critical part is designing a stable API layer for no-code platforms, so I'll implement structured JSON request/response models, webhook authentication, conversation state management, and handoff payloads that [login to view URL], n8n, or Zapier can consume without custom coding. Prompt engineering will be optimized for reliable product retrieval, order status lookups, and fallback handling. The solution will be modular, Docker-ready, and easy to extend as your store grows. As final deliverables you will receive a fully functional Python chatbot exposed through FastAPI. - Webhook-ready API documentation for [login to view URL], n8n, and Zapier integrations. - Product data ingestion and update documentation. - Clean setup, deployment, and integration guide. - Well-documented source code with configurable prompts and API settings. One thing I'd like to confirm before we start: which e-commerce platform powers your store, and is order tracking available through an existing API? Regards, Imran.

Hi, I see the main challenge is building a Python-based AI chatbot with FastAPI that’s modular enough for no-code integrations, not just another standalone bot. I once built a similar chatbot for a retail client using FastAPI and LangChain, where we had to structure the API responses to work smoothly with Zapier—turned out the first version needed some tweaks around payload validation. I’d approach this using FastAPI for the backend because it keeps the API clean and scalable while avoiding monolithic designs. The biggest improvement will come from pre-defining strict input/output schemas for the no-code platforms. I always test each integration step separately before connecting everything, so you can review changes easily. The goal isn’t just the chatbot itself, but a system that’s easier to maintain and can scale with your store’s product catalog. If we’re aligned, I can start right now. Thanks, Denis.

Hello, Most chatbot builds like this quietly fail for one reason. The team pours all its energy into the LLM and the clever replies, then wires the store data in at the end as an afterthought, and the bot starts confidently giving customers wrong prices and stock. I build it the other way around. I start with the data grounding and the API contract, so every answer about specs, pricing, and availability comes from your real product feed and not a guess. The FastAPI endpoint is designed as a clean bridge from day one, accepting webhook calls from Make, n8n, or Zapier and returning structured JSON your workflows can act on, including a clear handoff payload when a human needs to step in. Order lookups and the shipping and returns FAQs sit on the same predictable contract. Once that core is solid, a natural next step is a light logging layer so you can see what customers actually ask and keep sharpening the answers over time. You get working code plus plain setup and integration docs so anyone on your side can maintain it. I can start right now. Regards

An e-commerce chatbot works best when it understands the store data, not just answers generic questions. The key is connecting product information, customer queries, and automation workflows into one reliable system. I can help build an AI-powered chatbot backend with API-based architecture, product data integration, customer support flows, and webhook-ready endpoints for tools like n8n, Make, or Zapier. I have experience building e-commerce platforms, custom APIs, automation workflows, and full-stack applications. I can structure the solution so product data updates, fallback handling, and future integrations remain easy to manage. A good starting point would be understanding your current store setup: are products and orders available through an API, or should the chatbot initially work from CSV/product exports? I can review your workflow and suggest the best implementation approach. Best Ahtesham

Hi! This is something we can definitely build. Before I size it properly, one thing I need to understand: what's the e-commerce platform — Shopify, WooCommerce, something custom? That changes how we pull product and order data, and whether we're hitting a native API or ingesting CSVs. On the stack, FastAPI as the backbone makes total sense, and we'd wire it to an LLM (likely Claude or OpenAI depending on your preference) with the product catalog fed in as context. The webhook layer for Make/n8n/Zapier is straightforward — structured JSON in, structured JSON out, with a clean handoff payload when a human needs to take over. One honest note on the budget: depending on how live the inventory sync needs to be and how many edge cases the conversation flow has to handle, the lower end of the range might be tight. Worth a quick chat on scope before committing. Looking forward to hearing more about the setup. Gustavo & the DoTheCode team

Hi, what caught my attention is that you're designing the chatbot as an API-first service that can plug into no-code platforms. Keeping the AI layer separate from the integration layer will make the system much easier to maintain and extend. I have experience building AI-powered backend services with Python, FastAPI, REST APIs, OpenAI integrations, and automation workflows. I can build a modular chatbot that ingests product data, handles customer support and order tracking, exposes webhook-friendly endpoints, and integrates cleanly with platforms like n8n, Make, or Zapier using structured JSON responses. Could you share which e-commerce platform or backend the chatbot will integrate with (Shopify, WooCommerce, a custom API, or something else)?

Hi – Nemanja here from Serbia, to help build an AI chatbot that can actually support your e-commerce workflow instead of only answering basic questions. An AI shopping assistant only works if product data, customer conversations, and automation flows stay connected with reliable responses and structured outputs. I noticed you mentioned FastAPI, n8n/Make/Zapier integration, product CSV/API data, and human handoff payloads – that usually means the chatbot needs a proper backend layer, so I'd design it with clear APIs and scalable conversation logic. I would build the Python FastAPI chatbot with LLM integration, product knowledge handling, webhook support, and documentation for future workflow extensions. I've built automation systems, APIs, and AI-powered applications using Python-based architectures. Quick question: is your product data currently stored in a specific e-commerce platform, CSV files, or another system? Looking forward to hearing from you.

I've built FastAPI-based LLM integrations handling structured product data and no-code triggers before, so this is straightforward. I'll scaffold the FastAPI endpoint first, wire in LangChain for the chat logic with OpenAI's API, then expose a schema-validated JSON interface for Make/n8n/Zapier. For the e-commerce side, I'll parse CSV/API product feeds into a SQLite/Postgres cache with incremental sync to avoid stale data. The conversational layer will include fallback handlers, order status lookup via Shopify/Magento API, and a handoff payload structure for human escalation. I'll containerize it with Docker and include a minimal setup README. I can start immediately. Thanks, Andrii.

The webhook boundary is what I'd pin down first: FastAPI should expose one fixed JSON request/response contract that n8n, Make or Zapier can call without guessing what fields the chatbot expects back. For product, pricing and order-status answers, I'd keep store data ingestion separate from chat handling, so you can refresh catalog/order data without redeploying the bot logic. I'd build the FastAPI service with OpenAI/LangChain, structured responses, source-aware retrieval over product and pricing data, and a direct order-status lookup path for known customers or order IDs. I would also add clear fallback responses for missing SKUs, stale prices, unclear orders and webhook payload errors, since those are the cases that usually create support noise after launch. M1: API contract, FastAPI skeleton, auth/config, sample webhook request and response, $210.54, 2d. M2: Store data ingestion, product/pricing retrieval, order-status lookup flow, $213.73, 2d. M3: Chatbot response tuning, n8n import-ready workflow, no-code hookup docs and handover, $213.73, 2d. You'd have something n8n can trigger on day one, plus docs for Make/Zapier using the same payload shape. One thing I need to confirm before I price the ingestion path too tightly: is your store data coming from Shopify/WooCommerce APIs, exported CSVs, or an existing database?
