    OpenClaw RBAC & Notifications Setup
    6 giorni left
    Verificato

    I’m consolidating a group of Web, mobile, and desktop apps that all authenticate through the OpenClaw stack, and I need one coherent Role-Based Access Control configuration to govern them. The goal is to define every permission once, apply it consistently across each application, and have automatic notifications fire whenever roles or privileges change. Here’s what I want to come out of this engagement: • A clean, documented RBAC schema in OpenClaw that maps roles to fine-grained permissions and can be consumed by every client app. • Integration code (middleware or service hooks) that makes each application respect the new role definitions. • A notification workflow—email and push first, with SMS kept in mind—that broadcasts events such as role ...

    I need an open, fully documented REST-style API that can sit between Ship ERP and our in-house Truck Management System, letting the two platforms talk to each other in real time. The core responsibilities of this new layer are: • Real-time status updates – the moment a shipment moves, both systems must reflect it. • Data synchronization – orders, loads, and reference data must stay consistent on both sides. • Rate engine – an endpoint that can accept lane details, weight, and accessorial flags, then return our calculated rate instantly. Key data points that the endpoints must expose or consume include tracking numbers, current shipment status, and system-generated rate calculations. Technical expectations – JSON over HTTPS; versioned endpoint...

    Fix Broken Backend Deployment for Live E-commerce Site URGENT — React + FastAPI/Node + MongoDB My e-commerce website is live but login, payment, and orders are broken because the backend was never deployed properly. Need an experienced full-stack developer to fix this in 1–2 days. Current Setup • Domain: (live) • Frontend: React (Create React App) — already deployed on Vercel • Backend: FastAPI / Node + MongoDB — NOT deployed (code is in GitHub) • Originally built on: Emergent AI, then exported to GitHub • Integrations: Razorpay, Google OAuth, SendGrid The Problem REACT_APP_BACKEND_URL in Vercel is pointing to the frontend domain itself instead of a real backend. So login, payments, and orders all fail. All API keys have already been ro...

    Secure Google Ads API Token
    5 giorni left
    Verificato

    My Google Ads account is not yet approved for API access, and I need a specialist who can take me from zero approval to a live developer token. The goal is simple: have Google grant my account the standard “Production” access so I can start making authenticated API calls for future campaign automation and reporting. Here’s the journey I expect us to cover: • Review my existing Google Ads setup (currently only basic ads manager access). • Advise on any prerequisite steps—manager account creation, billing verification, or policy tweaks—so the application stands the best chance of success. • Prepare and submit the API access application inside the Google Cloud Console & Ads UI, including the mandatory Use-Case explanation, app name, OAuth...

    We are looking for an experienced developer or development team to build a browser-based eBay management system similar to inkFrog. The system must connect to multiple eBay seller accounts/stores and allow us to manage listings, inventory, orders, SKUs, HTML templates and bulk listing edits from one dashboard. We currently use inkFrog and need a long-term replacement platform for our business operations. This is NOT a simple listing tool or scraper. We require a proper scalable business system with a clean UI and strong eBay API integration. We are looking for long-term development and future expansion, not just a one-off script. --- # Main Features Required ## 1. Multi eBay Store Connection * Connect multiple eBay seller accounts/stores * Secure OAuth login/token handling * Abilit...

    I run Workday as our HR backbone and already automate a number of processes with Workato recipes. The next step is to plug Adobe Learning Manager into that same flow so every employee record, enrollment and completion event moves cleanly between the two systems without manual effort. Here is what I need you to wire up: • Course enrollment sync • Completion status updates • User data management You should be comfortable working with Workato connectors, Workday Web Services, and the Adobe Learning Manager REST APIs, building reusable recipes, handling OAuth tokens, and mapping custom fields that don’t line up out-of-the-box. I’ll pass you access to our lower-environment tenants first; once the integration is stable, we’ll promote it together to produ...

Your work is considered complete when every workflow is running error-free in production, the custom n...
