    My n8n instance drives customer outreach through Twilio for both WhatsApp and SMS. After I recently updated message templates, rotated API credentials, and rearranged several workflow steps, everything went sideways: WhatsApp messages never leave the workflow, and SMS reaches clients without the subscription code variable that should be injected. I need the current workflows reviewed end-to-end, the root causes isolated, and the issues fully resolved. A solid grasp of Twilio’s Messaging/Conversations APIs (WhatsApp & SMS) and hands-on n8n debugging is essential, along with clear communication so I understand exactly what went wrong and how to prevent a repeat. Deliverables • Repair the existing n8n workflows so both WhatsApp and SMS messages are sent successfully, wi...

    I need an extra pair of senior-level eyes to help our customers finish wiring their PHP 5 or Laravel 7 apps into our REST API. Your role is purely advisory: jump on short calls or chats, review snippets, and explain why a request fails or what header is missing.

    I’m working with an API where the data used to be exchanged as JSON, so I already know the structure of the payload. Recently, however, the same endpoint started returning data as application/octet-stream instead. What I need help with is understanding how to correctly handle this change: how to inspect what the request body is actually sending, and how the response should be interpreted or decoded so the system continues to work properly. All required data is already available on my side. The main challenge is figuring out how the octet-stream format is constructed and how to send and receive it in the way the API expects, instead of plain JSON. I’m looking for a small, clear solution (Node.js or Python is fine) that can capture the exact request (URL, headers, body), read ...

    I’ve mapped out a process to apply to roles on LinkedIn, Indeed, and Glassdoor automatically and now need a polished n8n workflow that ties it all together. You’ll receive my CV, cover-letter templates, and the messaging formats I already use. Your task is to translate that into a clean, modular n8n setup that can: • pull each opportunity from a sheet or form, • generate the appropriate documents from my templates, • submit the application through the portal’s API or form endpoint, and • notify me once the application lands. Standard fields are fine; no elaborate custom objects are necessary—just a rock-solid flow that I can tweak later without digging into code. Please make the nodes readable, add brief inline notes where the logic isn&...

    I will hand over raw video files along with a folder of still photos and need them shaped into polished content for three destinations: YouTube, Instagram Reels, and TikTok. The visual tone I’m after is professional and clean—think crisp color correction, smooth cuts, tasteful lower-thirds, and on-brand typography rather than flashy effects. Here’s what the finished work should cover: • One medium-length 16:9 edit (roughly 3–8 minutes) tailored for YouTube, complete with intro, outro, royalty-free background music, and balanced audio. • A set of short-form vertical clips (15–90 seconds each) optimized for Instagram Reels and TikTok, including burned-in captions where dialogue is key and quick hook openers to keep viewers watching. • Separate e...

    I need a small, reliable service that connects to Binance’s public endpoints (REST or WebSocket) and streams live market data and prices for every trading pair I specify. Each tick, order-book snapshot, or aggregated trade you pull should be pushed out in clean, well-structured JSON that I can drop straight into my existing analytics pipeline. Core expectations • Real-time feed: latency kept to a minimum, with automatic reconnection and graceful handling of API rate limits. • Flexible symbol list: I should be able to add or remove pairs without touching the code. • Output: pure JSON—either batched to a file, posted to an HTTP endpoint, or inserted into a queue (your call, as long as it’s documented). • Runtime: a lightweight script or containe...

    I already have a fully built n8n workflow that ties TextMagic SMS, OpenAI-generated replies, Supabase lead records, and Base44 reporting together, but it is not running end-to-end without hiccups. The most troublesome section is the TextMagic layer—messages sometimes refuse to send or arrive, and that single failure blocks every downstream action. Here is what I need from you: • Import the JSON I provide into your n8n instance and trace every failing node, starting with TextMagic. • Repair the messaging logic so outbound and inbound SMS flow consistently, then verify that the OpenAI code nodes still parse and format JSON correctly. • Confirm that Supabase updates fire only once per lead and that Base44 receives clean, real-time data. • Keep my existing arc...

    I need a seasoned Moodle core architect to trace and resolve a series of functionality bugs that are affecting day-to-day use on my live site. The symptoms range from features silently failing to occasional fatal errors when certain activities are saved, so this is not a simple plugin tweak—I’m looking for deep, core-level diagnostics and clean, maintainable patches. Your task is to identify the root causes in core code, implement fixes, and confirm that every affected workflow runs smoothly again without introducing regressions elsewhere. You may have to step through the plugin architecture, examine the database schema, and validate calls to Moodle’s web-service APIs to be sure the problem is fully solved. Deliverables • A concise report outlining the source of ...
