I have a live WordPress site tied to my WHMCS installation and need two very specific improvements. First, I want true single-sign-on: users should be prompted to log in with their Google account (OAuth 2.0 / OpenID Connect). If that succeeds, they land inside WordPress already authenticated in WHMCS. If Google is unavailable or the user declines, the system must fall back gracefully to the regular WordPress login screen and still pass the session through to WHMCS. Second, the Domain Checker must sit seamlessly inside WordPress while continuing to pull availability data from WHMCS—no separate WHMCS page. Styling should inherit my current theme automatically so it looks native. I only need these two features; no extra modules or cosmetic tweaks. Once you finish, give me the upd...
NEED TO BE DONE IN LESS THAN 24 HOURS MAKE SURE U DM ME IF UR INTRESTED AND WHAT U BID IS WHAT U GET Work is Done ON ----------------- Objective Recover a competitive API hold path (if still possible) and improve hold performance under heavy competition. Current behavior is mainly: WS + ChartRender fallback Hold-only mode (no auto-checkout) Multi-holder distributed accumulation Primary problem: API hold path is effectively unavailable on target events, so fallback path loses races. What Works Now Event detail fetch works (event_id, event_key, workspace, pricing, limits). Session restore + token bridge works. Seat discovery/polling works. ChartRender selectObjects executes very fast (few ms). Hold-only flow is strict (no checkout automation). What Fails Now API hold endpoints appear dead...
I’m calling the /challenge/v1/continue endpoint with a POST request, sending a JSON payload and passing my API key in the headers, yet the server keeps replying with HTTP 403. I’d like you to pinpoint why the call is being rejected, adjust the headers or signing process as needed, and hand back a fully working example so I can reproduce the success on my end. You’re free to use Postman, curl, or any other HTTP client while troubleshooting; just make sure the solution works consistently once my key is swapped in. Deliverables 1. A tested request sample (curl command or Postman collection) that returns a non-403 response. 2. A concise explanation of the authentication or header changes required so I can apply the fix to other endpoints. # Roblox

I’d like you to build a full-stack n8n workflow that turns my LED-TV showroom content into AI-generated promos and publishes them automatically on a tight schedule. Here’s the flow I’m picturing: text prompts or simple spreadsheet entries drop into n8n, the scenario calls OpenAI/Claude/Gemini to script a short product-promotion video, passes the script to my preferred video-creation tool, saves the rendered clip plus a matching product image to Google Drive, then posts everything on the right channels without me lifting a finger. Platforms that must go live: • YouTube Shorts • Instagram Reels • Facebook Key details you’ll cover – Clean install and configuration of n8n on my VPS (or a managed option you recommend) – Secur...
I am looking for a quote to develop an automated trading bot for Polymarket via the CLOB API (Polygon network) specializing in Cricket and Baseball markets. The core requirement is a real-time execution engine that monitors market prices (winning probabilities) via WebSockets for low latency. The bot must implement a specific logic: Automatic Entry when a team’s ‘Yes’ token price reaches $0.90 (90%) and a Hard Stop-Loss that triggers an immediate sell order if the price drops to $0.70 (70%). The system must include secure local management of private keys (via .env), robust error handling for API timeouts or connection drops, and a simple configuration file to set position sizes and target market IDs. Please provide a quote including estimated development time, hosting rec...
I need a lightweight Image CAPTCHA added to my existing sign-in form so that every user interaction is verified before the request reaches the server. The challenge should present a set of simple object images (think cats vs. dogs, cars vs. bikes—no cluttered scenes) and require the user to pick the correct item in order to continue. Here’s what matters most: • Accuracy and speed: the CAPTCHA has to load quickly and flag bots reliably without delaying real visitors. • Clean, accessible code: please write modular, well-commented PHP/JavaScript (or a similarly common stack) so I can tweak imagery or thresholds later. • Server-side validation: after the browser picks up the user’s choice, I want a secure back-end check to prevent spoofing. • Sea...
I’m rolling out Gemini across the enterprise with a clear, first-phase objective: streamline our Project site data and financial data flow by linking Gemini directly to the Google Sheets models that many teams still rely on for daily reporting. The end-state I’m after is a single, trusted data layer that Gemini can expose to analytics and downstream applications in near-real time, removing the manual exports and copy-paste steps that slow us down today. This engagement is focused on: • Configuring Gemini so it can ingest, transform, and publish our Google Sheets financial datasets with full schema mapping and refresh scheduling. • Setting up secure authentication and any required service accounts, making sure permissioning follows least-privilege principles. ...
I need a single Excel workbook that lets me broadcast personalised WhatsApp Business messages straight from the sheet. Core flow is simple: • I drop or paste a contact list into a dedicated sheet (structure: phone number, name, any merge fields you feel are useful). • I type one master message that can pull those merge fields so every recipient gets a tailored text. For this first release we will stick to text-only messages; later on I may ask you to extend it to images or documents, so please keep the code modular. • When I hit “Send”, your VBA (or Office Script) routine should call the official WhatsApp Business API, handle authentication, queue the messages and confirm each send. Stability is key. The workbook must trap API errors, surface clear status m...

I need our KarbonHQ workspace streaming continuously into Snowflake so that Claude can run live analytical prompts on up-to-the-second data. The pipeline must pull every element KarbonHQ’s API exposes—customer information, all task and project objects, plus the full communication history—and land it in Snowflake in a query-ready schema. Once the data is in Snowflake, Claude has to “see” it immediately. Whether you choose Snowpipe, Kafka, Fivetran, or a custom Python microservice is up to you, as long as latency stays low enough to feel real-time from the user’s perspective. Deliverables • Automated connection to KarbonHQ that captures customer records, task & project data, and communication threads the moment they change • Snowflake t...
I already have the AI-driven multi-restaurant ordering system – running, but it still feels like a collection of parts rather than a seamless marketplace. I want to take it to full production status on a single Hostinger VPS, with every critical workflow automated and polished for real-world customers and vendors. Here is what I need done: • Stripe Connect integration end-to-end so payouts flow automatically the moment an order is completed. Restaurants, drivers, and the platform each receive their share without manual intervention, and disputed or failed payments are handled gracefully. • Automated logistics: when an order is placed the nearest available driver should be assigned, the customer and restaurant see real-time driver location, and ETAs update continuousl...
I already hold an active Meta developer account, but I need another set of expert hands to turn that account into working, refreshable access tokens for both Facebook and Instagram Threads at the same time. The goal is simple: by the end of the engagement I want you to run a quick test postman call and confirm that I can create, read, and update content on both platforms with a stable, long-lived token. Read-write scope is essential; nothing less will do. What I expect from you • Configure the existing Meta app so that the required permissions for Facebook Pages and Instagram Threads publishing are approved or in review where necessary. • Generate short-lived tokens, exchange them for long-lived ones, and document the refresh workflow so I can repeat it without you later....

I’m running a project on Hostinger’s Horizon platform and every API call is currently failing with a “data retrieval error.” The issue isn’t limited to a single route—every endpoint I test returns the same response. All requests are authenticated with an API key, so it’s not OAuth or a basic-auth problem. Here’s what I need: • Diagnose why the Horizon API refuses to return data when an API-key header is supplied. • Implement and test a clean fix—whether that’s correcting headers, adjusting CORS, rewriting routes, or updating server-side settings—until each endpoint delivers the expected JSON response. • Provide a concise report of the root cause and the steps you took so I can reproduce or roll back if n...

I’m building a multi-tenant, cloud-hosted network management platform that lets each of my customers create their own account, register devices by MAC address and manage everything from a single web interface. Core device scope • Routers, switches and access points must be discoverable and enrollable without manual intervention once the customer submits the MAC. Essential features for customers • Live and historical uptime / downtime, traffic statistics and error logs presented in clear dashboards. • Remote network-settings changes plus bandwidth-monitoring tools surfaced through an intuitive GUI. • A captive portal module so hotels and similar venues can issue guest Wi-Fi credentials on the fly; voucher or self-registration flows are both acceptable a...

I already have several boards running on , but the automations and integrations that should tie everything together are still patchy. My main objective is simple: I want a fully working system that I can trust every day without babysitting it. Right now the critical pieces are: • Automations that move items between boards, trigger status changes, and keep data flowing in real-time • Two-way links with Google Calendar and Calendly so dates stay perfectly in sync • Webhook–based connections to a few custom services What I need from you 1. Audit the current setup, map out every automation and integration, and identify where things are failing or overlapping. 2. Rebuild or fine-tune the automations so they fire reliably and in the correct order. 3. Config...

I already have a vehicle-service request flow running in Lovable that stores every submission in Supabase, including the image uploads. What I now need is the automation layer that hands the data to Make (Integromat) and then fires off a structured WhatsApp message. Here’s the exact flow I want you to build while connected to my machine via AnyDesk: • On form submission Lovable should trigger a webhook to Make. • Make must ingest every field plus the public URLs of the uploaded images. • A WhatsApp template I’ve prepared is then populated with the customer name, phone number, repair / service description and either image links or the images themselves. • When the send attempt returns, write the status straight back to Supabase: “sent” on ...

I want an Excel workbook that connects to the (public access) and continuously pulls the Nifty 50 option-chain data I specify: the at-the-money strike, plus five strikes out-of-the-money and five strikes in-the-money. For each of those eleven strikes the sheet must capture three fields—Open Interest, Change in Open Interest, and Volume Strike Price—and refresh them automatically every three minutes. Inside the file I need a time-stamped line graph that updates in real time, plotting the same three metrics so I can watch how they evolve through the session without touching the sheet. A single click to start or stop the refresh loop is fine; otherwise the process should run silently in the background. Please build with whichever approach inside Excel you prefer—VBA, Powe...

I need a SIP trunk sourced from the United States that comes with at least one DID number, delivers rock-solid reliability, and offers self-service access on par with Twilio (API, online dashboard, real-time monitoring, etc.). The trunk will carry both local and international traffic, so consistent call quality and proven carrier routes are non-negotiable. My existing setup runs through a PBX system. Your job is to help me choose or broker the right carrier, secure the numbers, and complete the technical cut-over so calls flow seamlessly through the PBX without service disruption. Key expectations • 100 % uptime or SLA that truly rivals Twilio • Full documentation of trunk credentials, SIP endpoints, and API details • End-to-end testing—originating and termin...
I need a clean, production-ready Python script that plugs into the Dhan API and its WebSocket feed to automate a single intraday play on the current-week NIFTY PE that is three strikes in-the-money (ATM-3). The strike must be picked using the ATM-3 premium itself rather than the spot or futures price. Logic • ema + time based logic • Stop-loss 10 % and target 20 % must be attached instantly. and time based universal exit • If another position exists in the account the strategy simply ignores it and proceeds with its own rules—no forced square-off or alerting. Implementation notes The solution has to rely on Python 3.x, leverage Dhan’s REST endpoints for order placement, and keep WebSocket streaming alive for real-time pricing and stop-loss/target manag...

I’m ready to put real capital behind an already-profitable, fully automated trading bot. The market isn’t important to me—crypto, stocks, forex, or a cross-asset strategy are all welcome—as long as the live results are positive and repeatable.
