From 18,174 reviews, clients rate our OAuth Developers 4.9 out of 5 stars.I want a clean, mobile-friendly web application that combines a lightweight CRM with a secure authentication layer. Two user roles—Admin and regular User—should be able to sign in through OAuth and then see only the functions relevant to them. Core CRM needs: • Contact management that lets me create, edit, tag, and search contacts quickly. • Lead tracking that shows status, notes, and simple progress metrics. Beyond those essentials, the interface must remain fully responsive on phones, tablets, and desktops. The backend should be structured so future modules (analytics, reporting, etc.) can slot in without a rewrite, and I expect clear separation between frontend UI and API services. Deliverables • Source code with README covering setup, environment...

I need a clean, production-ready Shopify OAuth flow wired into my existing web application so that store owners can click “Connect with Shopify”, authorize, and be dropped straight back into the app without friction. Once the token is stored, the app must automatically pull every product in the merchant’s catalog—no category filtering, every single item—via the Shopify Admin API and keep it in sync on an ongoing basis. The sync needs to include: • Price data for each variant • Full product descriptions • All images (with their positions and alt text) • Real-time inventory levels A webhook or other event-driven approach is preferred so updates appear quickly rather than relying solely on scheduled polling, but I’m open to ...
I run OpenClaw as the hub for our internal workflows and now want it talking seamlessly with the wider Google ecosystem and a few other business apps. The immediate goal is to establish secure, reliable connections so OpenClaw can pull and push data, kick off automated processes, and surface real-time alerts without anyone having to copy-and-paste or bounce between tabs. Google services are first on the list—Drive, Sheets, and Calendar are all in scope—followed by others. I’m open to your recommendations on sequencing and best-practice architecture, but the end result should let us:
I’m ready to roll out a fully web-based ordering experience for my restaurant. Diners will scan a QR code that lives on their individual table, land on a mobile-friendly website, browse the menu, and send their order straight to the kitchen—no native apps, downloads, or kiosks required. Core requirements • A unique, auto-generated QR code for every table so orders are always tagged to the correct location. • The site must run smoothly in any modern mobile browser (iOS or Android) as well as on desktop for back-office use. Essential features to build in: 1. Track table occupancy in real time so staff can see which tables are open, waiting for food, or ready to pay. 2. Seamless payment integration (card wallets, Apple Pay / Google Pay, or Stripe-style checko...
I want a web platform that lets Murder Mystery 2 players stake their Roblox items in real-time games—coin flip, jackpot and an upgrader—modelled as closely as possible on the look, feel and flow of bloxybet.com. Coin Flip • Any number of coin-flip rooms can run in parallel. Players should be able to open a room, set the wager, share the link and wait for an opponent, or instantly join an open room. The interface needs the same fast, casino-style experience Bloxybet offers, with live status updates through WebSockets or a similar solution. Jackpot & Upgrader Both games must mirror Bloxybet’s mechanics: tier-based jackpot pools that roll on a timer, and an upgrader where players select an item, choose a percentage chance and see an animation revealing suc...
I already have a pre-approved promotional template and a list of phone numbers sitting in Google Sheets. What I need is a clean Google Apps Script (or small set of scripts) that connects to WhatsApp Cloud API, authenticates with my Meta token, and fires that single template message to every number in the sheet. Scope of work • Authorise the script with WhatsApp Cloud API, store the access token securely, and handle refresh logic. • Build a simple menu item or button inside the Sheet so I can trigger the send on demand. • Read numbers from a designated column, batch the calls to respect WhatsApp rate limits, and log success / failure back into the sheet in real time. • Provide clear setup instructions so I can reuse or copy the script to other sheets later. Accep...
Saya ingin meluncurkan sebuah aplikasi media sosial yang bisa menjadi sumber pemasukan tetap bagi saya. Fokus utama aplikasi ini adalah fitur berbagi foto dan video yang mudah serta menarik, sehingga pengguna betah berlama-lama dan aktif berkontribusi. Pendaftaran pengguna akan dilakukan melalui akun media sosial lain—khususnya Facebook atau Google—agar proses onboarding singkat dan tanpa hambatan. Dengan demikian, saya berharap basis pengguna bisa tumbuh cepat tanpa perlu mereka membuat akun baru dari nol. Yang saya butuhkan: • Pengembangan aplikasi inti (Android atau cross-platform) dengan komponen feed foto/video, unggah, like, dan komentar. • Integrasi login menggunakan OAuth Facebook dan Google. • Fondasi monetisasi dasar—misalnya penempatan ikla...
