OAuth is an authorization protocol enabling a third-party application to access resources, such as data and content, from another resource provider system on behalf of a user. An OAuth Developer is a specialist who has the technical capabilities to facilitate the secure transfer of data from one system to another. OAuth Developers work with clients who want to enable their users to transfer data from one application to another, as well as enable access to external resources with out having to provide credentials.

Essentially, OAuth Developers are responsible for ensuring that the proper security measures are in place for this data transfer, and interoperate various components in order to make it all happen. OAuth Developers require extensive knowledge in backend technologies and security protocols.

Here's some projects that our expert OAuth Developer made real:

  • Building secure single sign-on solutions (SSO)
  • Creating and configuring secure authentication between applications
  • Connecting web apps with external data sources, such as Office365
  • Developing mobile applications with cross platform functionality and secure integration
  • Developing visualizations for IOT systems using React, SGV and Elixir
  • Implementing OAuth 2.0 authentication protocols in different platforms, such as WP or Laravel
  • Integrating APIs with partner websites for secure authentication
  • Developing web apps with authentication protocols in .Net Core 6 and Angular

Our team of highly skilled OAuth developers have completed all kinds of projects related to ensuring the secure exchange of data between applications. If you are looking for a reliable way for your users go authenticate themselves on other systems securely, our developers can be trusted to deliver results on Freelancer.com. We invite you to post your own project now and hire an experienced OAuth Developer from our team!

    Next.js App With Live Data
    4 дні(-в) left

    I already have the finished Figma designs and now need the build in Next.js. The core of the job is to translate those screens into a production-ready application that includes secure user authentication, smooth API integration and true real-time data updates (think WebSocket or Server-Sent Events rather than timed polling). You’ll start by setting up a clean codebase, wiring up the auth flow (email/password plus social log-ins via OAuth), then hooking the front end to my existing REST endpoints. After that, we’ll layer on the live updates so a user sees changes instantly without refreshing the page. Deliverables • Complete repository reflecting the approved designs • Auth module fully tested and documented • Connected API calls with proper error handli...

    Automate LinkedIn Outreach Workflow
    3 дні(-в) left
    Верифіковано

    I already have n8n installed and running; what’s missing is the set-up of two marketing-automation workflows centred on LinkedIn. My account is connected and all copy, images and post dates are ready to go—I simply need the flows built, tested and documented. The first workflow should publish scheduled posts to my LinkedIn company page and personal profile. The second should handle personalised outreach: pulling prospect data from a Google Sheet (or similar), sending connection requests or follow-up messages, and logging the response status back to the sheet. Please use native n8n nodes wherever possible and keep any custom code lightweight and well-commented. Error handling, retries and a Slack (or email) alert when something fails are important so I can trust the automation...

    I’m building a new web application in C# and need a developer who can deliver a complete, production-ready authentication and login system. The core requirements are: • Traditional email + password registration and sign-in, with secure hashing, password reset, and account verification. • Social sign-in via Google and Facebook using OAuth2, seamlessly tied to the same user profile. • Two-factor authentication that can be activated per user, preferably through an authenticator app or fallback email code. I’m open to the exact stack, but an ASP.NET Core solution with Identity, external login providers, and JWT or cookie-based sessions would fit perfectly. Clean separation of concerns, clear naming, and defensive coding practices are expected. Deliverables 1...

    OpenClaw RBAC & Notifications Setup
    1 день left
    Верифіковано

    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

    Верифіковано

    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...
