我正在使用 OpenClaw 作为业务后台，希望把 TikTok 账号完整接入其中，以实现更高效的用户互动。核心目标是让系统能够直接对接 TikTok API，帮助我在后台就能： • 自动抓取并显示视频的实时点赞、评论数据 • 一键回复或点赞评论，提高互动频率 • 监控粉丝增长，并输出每日/每周统计报表 我最看重的是「用户互动」效果，因此在技术实现之外，也请为我预留拓展空间，方便后续通过发布有趣的视频内容来持续提升粉丝量。 交付需求： 1. 搭建与 TikTok API 的安全对接（OAuth 授权、权限管理）。 2. 在 OpenClaw 中新增模块或插件，前端界面可查看与操作点赞、评论。 3. 粉丝增长分析：提供折线图及关键指标导出（CSV/JSON）。 4. 完整部署文档与简明用户手册，确保我无需额外开发即可维护。 如果你熟悉 TikTok 开发者工具、Webhook 以及常见的 Node.js 或 Python 框架，并能保证接口稳定、数据合规，请与我联系并简要说明你的实现思路与相关经验。

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...

I run five different mailboxes inside Outlook Classic on Windows, and only the Gmail-based business address has suddenly stopped sending or receiving. Outlook shows no visible error code—it simply does nothing. I have already removed and re-added the profile, so the usual reset steps are done. Microsoft support admitted there is a known handshake problem between Outlook and Gmail; apparently there is a specific fix involving the OAuth / IMAP settings that I don’t have in hand. If you’ve dealt with this exact Gmail-to-Outlook connection failure before and can get the account fully syncing again—without disturbing my other four accounts—let’s do it. Success is straightforward: after your intervention I must be able to press Send/Receive and watch new...

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. The focus is speed and reliability: users should see market movements the instant they happen and be able to act just as fast. 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 a developer who can configure the official WhatsApp Business API so my team can handle real-time customer support through live chat. The goal is simple: when a visitor messages our business number, the conversation should flow straight into an agent-friendly dashboard (whether that’s a custom front end, a CRM module, or a reputable third-party chat workspace—I’m open to your recommendation). Core requirements • Register and verify the WhatsApp Business account, then activate the Cloud API or on-prem setup. • Create or connect a live-chat interface where multiple agents can pick up, transfer, and close conversations. • Implement webhook endpoints for message events, delivery receipts, and agent activity logs. • Add basic agent presence i...
