    n8n IMAP PDF Forwarder

    Verified

    I need a straightforward n8n workflow that connects to my custom-hosted IMAP mailbox, polls the INBOX once every 24 hours, and processes only the messages that arrived since the last run. Here is exactly what the workflow must do: • Authenticate to the IMAP account (non-Gmail, custom server) and fetch only unseen emails. • Inspect each message for file attachments and determine whether at least one genuine PDF file is present. Ignore logos, signature images, embedded graphics, or any attachment that is not a PDF. • When one or more PDFs are detected, forward the email to a fixed destination address in plain-text format, preserving: – the original subject line – the email body converted to plain text – every PDF attachment found (if there...

    I’m launching a medium-scale online store that serves customers exclusively within my city. The site will sell physical goods only, so the buying journey must feel fast and friction-free from browsing to doorstep delivery. Core functionality I need you to put in place for this MVP: secure user registration/login, full product catalogue and cart flow, a checkout that accepts credit/debit cards, popular digital wallets, UPI, and a fallback Cash-on-Delivery option, plus separate dashboards for Administrators, Vendors, and Customers. I’m flexible on the tech stack—Laravel, Django, or a modern JavaScript framework such as React with Node/Mongo are all fine so long as the code is clean, well-documented, and scalable for future city-wide growth (think flash-sale traffic sp...

    I need a Telegram-based bot that monitors Instamart in near real time—ideally every few minutes—and pushes concise alerts straight to my chat. The bot must: • Check stock availability for selected SKUs • Catch any price drops or temporary discounts • Send a clean, human-readable message each time one of those events occurs I should be able to add or remove item URLs or product IDs through a simple command or configuration file, and adjust the polling interval without touching the code. If Instamart changes layout or endpoints, I expect graceful error handling instead of silent failure. Technically I’m happy with Python, Node, or Go as long as the solution uses the official Telegram Bot API and runs headless on a small VPS. Scraping or unofficial In...

    I’m looking for a skilled Shopify developer who can join me on a full-time basis to drive new projects from concept to launch. The priority is building customer-facing Shopify apps—features that live in the storefront, improve the shopper’s experience, and ultimately lift conversion. Theme tweaks and drag-and-drop edits are not what this role is about; you’ll be writing clean, production-ready code every day. You should feel at home with Liquid, Shopify’s REST & GraphQL APIs, and a modern JavaScript stack (React, Polaris, Node). If you have experience publishing to the Shopify App Store, I’d love to hear how you handled authentication, billing, and the review process. When you apply, focus on your relevant experience: the apps you’ve built, t...

    I want to launch an online storefront dedicated to pots of every size and style, and it needs to feel just as smooth on a phone as it does on a laptop. A responsive design is therefore non-negotiable. React, Vue, Angular, Svelte—use whatever modern front-end framework you trust, as long as the final result adapts perfectly to both desktop and mobile screens. The core of the job is to build: — A clean product catalogue where I can add, edit, or archive items, each with multiple photos, descriptions, prices, and stock counts. — Intuitive navigation and search so visitors find the right pot quickly. — A password-protected admin area for day-to-day store management. — A lightweight back-end (Node.js with Express, Django, Laravel, or similar) and database of your ...

    I maintain a fork of LibreTaxi (Telegram bot – GitHub repo here: ) and now need a new core feature: automatic fare calculation. Here is what I’m after: If you’ve built Telegram bots before or have touched LibreTaxi, that’s an advantage, but solid JavaScript/TypeScript skills and clear commit history are what really matter.

    I run a steel-trading company and want to weave ChatGPT into every customer-facing and decision-making point of the business. The goal is to have one cohesive solution that handles customer inquiries and support, sparks qualified sales leads, and continuously scans market data to deliver clear price-trend insights—essentially covering all of the above functions mentioned. Here is what I have in mind: • A responsive chat widget (web & mobile) that fields customer questions, checks stock/price data we supply, and routes complex issues to my team. • An automated lead-generation workflow that captures prospect intent from chat or web forms, scores the lead, and pushes it into our CRM. • A market-analysis module that pulls public steel indices or our proprietary ...

    I am looking for a developer to build a lightweight web-based security scanning tool that can analyze websites and detect a few common security issues. The goal of this project is to create a simple tool where a user can enter a website URL and receive a report highlighting potential security weaknesses. The application does not need to be extremely advanced. The focus is on a clean interface and detecting a few important vulnerabilities. Main Features The tool should allow the user to: • Enter a website URL to scan • Check if important HTTP security headers are present (Content-Security-Policy, X-Frame-Options, HSTS, etc.) • Detect if the site is running on HTTPS or HTTP • Identify missing security headers • Detect exposed directories such as /admin, /login, ...

    I’m building a web app on Replit and deploying it on Railway. Clerk’s components already render on the site and the user can submit their credentials, but after the redirect the page never reaches the dashboard—it just sits on the loading screen and repeats the sign-in loop. There’s no visible error message in the browser; the session simply never finalises. What I need • Review my current Clerk configuration (frontend and backend keys, JWT settings, callback URLs, environment variables). • Check the Replit dev environment versus the Railway production build for any mismatched origins or missing secrets. • Correct any routing or middleware that might be blocking the session token from persisting. • Confirm that, once fixed, a successful ...
