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.

A partir das avaliações de 18,736, os clientes avaliam nosso OAuth Developers 4.9 de 5 estrelas.I need a cross-platform mobile application, fully integrated with our Salesforce org, that lets me see where my field agents are at any moment and capture their activity in real time. The app must run smoothly on both iOS and Android and authenticate with Salesforce (OAuth) so users log in with their existing credentials. Core workflow • Agents open the app, allow GPS, and their live location streams to Salesforce. • A single Map view plots every active agent, auto-refreshing as positions change. • When agents arrive at or leave a site, they tap Check-in or Check-out; these actions create (or update) a custom object record tied to the account, case, or work order we specify. • Managers can pull quick, on-device reports and analytics that summarise time on sit...

I need a full-featured website for our competitive online hockey league that ties seamlessly into the platforms our players already use. All users must authenticate through Discord OAuth, then verify themselves by linking an Xbox Live or Playstation Network account. Once inside, the site will surface real-time player, team, and league statistics that I will supply through an external data source (populated Google Sheet spreadsheet cells from third-party API); your job is to pull, cache when sensible, and display that data in an attractive, responsive front end. Two permission-based back-office areas complete the build: Team Management Portal This area is visible only to authorised team staff and must include: • Roster management (add, release, or trade players) • Player p...
I am expanding my in-house ERP and need a clean, well-documented API for several custom modules that sit alongside our existing inventory, HR, and accounting areas. The current system already exposes sandbox and production endpoints with separate keys, so your work must plug neatly into that dual-environment pattern. Core requirement: the new endpoints must handle user authentication using an API Key strategy. If you want to architect them so we can add OAuth2 or JWT later, that future-proofing is welcome, but for now the live build must rely only on API Keys. You will create the APIs and test the endpoints, then hand over concise documentation that shows other developers exactly how to hit sandbox versus production, obtain or rotate keys, and handle typical error responses. Deliverable...
My team needs a robust, bi-directional link between Wrike and Encodify up and running within the next 4 to 6 weeks. The integration must keep workspaces perfectly in step by handling: • Data synchronisation of tasks, projects, comments, notes and user profiles • Automated task creation / status updates so neither platform becomes a manual bottleneck • Near real-time updates in both systems, triggered by webhooks or an equivalent event-based approach Wrike should push every relevant change to Encodify and vice-versa, with conflict-handling logic to prevent overwrites. A clean audit trail on both sides is essential so we can see exactly when and where items were updated. Deliverables 1. Source-controlled integration code (Wrike & Encodify APIs, REST/OAuth...
We are looking for an experienced developer to complete two focused updates on an existing live web application. The platform is already deployed and functioning, so the work must be done carefully without modifying unrelated modules or core system logic. 1. Google OAuth Integration • Implement Google OAuth login for the application. • If a user logs in with Google and the email does not exist in the system, automatically create a new user account. • Integrate the OAuth flow with the current authentication system so users are redirected back to the existing frontend route after successful login. • Ensure compatibility with the current backend authentication flow and JWT/session handling. 2. UI Update – Replace SVG Icons with Emojis • Replace all SVG icons...
I have an Angular front-end that now needs secure Single Sign-On through Auth0. The only identity provider I want wired up at this stage is Google, and I only need to pull the user’s basic profile information once authentication succeeds. Here is what I’m expecting from you: • Configure Auth0 and my Angular project so a user can click “Sign in with Google,” be redirected to Google, grant consent, and land back in the app already authenticated. • Expose the returned ID token and profile object inside an Angular service so the rest of the app can subscribe to authentication state. • Add a simple route guard that blocks protected routes when the user is not logged in. • Include a clean logout flow that clears the session both locally and in ...
I need a fully functional real-time stock-trading application that runs on both iOS and Android.

What must be in the first release: • Live stock prices and interactive charts streamed with sub-second latency • Instant buy/sell order execution wired to a reputable brokerage API • Secure user account management for sign-up, KYC, portfolio view, and transaction history You’ll design the UI, build the mobile front-end, integrate real-time data feeds, and set up any supporting back-end needed for authentication, push notifications, and data caching. Clean, well-documented code in a Git repo is required for hand-off to my in-house team. Ex...
I need an expert at Aircall API to connect Aircall account to Google Sheets and keeps everything in sync without manual intervention. The script should: • Log every inbound and outbound call (number, agent, tags, duration, recording link, notes, etc.) to a dedicated sheet the moment the event is fired. • Stream real-time call status updates—ringing, in progress, ended—into a live dashboard so supervisors can monitor activity as it happens. • Generate automated daily and weekly reports that aggregate key KPIs and drop them into pre-formatted report tabs • Leverage Aircall’s SMS endpoints so I can send and receive texts directly from the spreadsheet interface, with each thread neatly appended to the relevant contact row. • Expose the cleaned...
