    My salon site, , runs on WordPress and needs a professional touch to tighten security and sharpen its search visibility.

    I need a small C# console application that signs in to a generic web service protected by oAuth 2.0, fetches the access token, and prints or returns it for downstream use. Everything has to run head-less: no Selenium, no hidden browser windows—just direct HTTP calls through HttpClient (or RestSharp if you prefer). Login method: username + password only. For my own Microsoft-based test account an MFA push may appear; I will approve that manually on the authenticator, so the program only needs to wait and continue once the provider finishes the flow. For the production account there is no MFA, so the same username/password path covers both scenarios. Key requirements • Pure console app targeting .NET 6 or later. • Uses the proper oAuth 2.0 flow to exchange credentials f...

    Hello, I have a landing page hosted on Cloudflare Pages. The domain and e-mail routing are already configured on Cloudflare, and the privacy policy and thank-you page are live. I need help setting up form submission e-mail notifications: • Admin notification with lead details • Customer confirmation e-mail (thank you + “we’ll contact you within 24 hours”) No backend server required — Cloudflare-native setup only (Pages Functions / Workers).

    Hi, ******Need someone ONLY AND ONLY from AUSTRALIA AND UK ONLY for my betfair apis development. I’m expanding an existing trading suite and now need clean, reliable access to Betfair’s Market Data API.

Scope of work – Connect to the Betfair Exchange API (non-interactive login is already in place on my side) – Retrieve real-time odds, price ladders and market status updates for Horse Racing, Football, Tennis and Cricket markets only – Structure the responses so they can be consumed by my Python back-end (JSON is fine) – Handle throttling limits and session renewal gracefully Deliverables 1.

    I need a small “agent kit” built for WordPress that drops straight into an existing theme and immediately connects to HubSpot and an API plugin. I want the agent kit to be capable of reading a document and comparing the information with our API Core goals • Add a front-end component (widget, shortcode, or block—whatever is leanest) that collects user info. • Authenticate securely with API and HubSpot and push each submission into the right portal, list, and workflow. • Keep everything WordPress-native—use hooks, actions, and settings pages rather than hard-coding Please outline your approach, any previous HubSpot API work, and an estimated turnaround. I’m ready to move as soon as the plan looks solid.

    I need a new subdomain created inside my Square space account so it points cleanly to , where all my online courses will live. has already supplied the precise CNAME and TXT records and I will pass those straight to you; they simply have to be entered without disturbing the rest of the zone file because other integrations are already running on the root domain. At the same time, I want my branded email address fully recognised by the CRM. That means adding or adjusting the accompanying MX, SPF, and DKIM records so outgoing messages authenticate and incoming replies land where they should. Deliverables • Subdomain resolves to the correct workspace over HTTPS and passes their custom-domain check. • Email records propagate, SPF/DKIM show “pass” in common tester...

    I need the latest release of Traccar GPS installed on a Linux server and left running with its default configuration—no custom server tweaks or device-specific rules for now. Once the service is up, I simply want to confirm that the web panel is reachable, the database is connected, and I can log in with the default admin account. Please take this on only if you have hands-on experience performing Traccar or similar GPS-tracking server installs on Linux. When you’re done, share the basic connection details and any quick commands I might need to start, stop, or check service status. That’s it—straightforward, clean, and ready for me to add devices later.

    Fix Opencart Waboxapp API
    1 小时 left
    已验证

    Our Opencart store has relied on the waboxapp API for about seven years to pipe WhatsApp conversations into our back-office. Everything ran smoothly until last week, when the integration simply stopped. The original error points to an “API key invalid or expired” problem. I already generated a fresh key inside waboxapp, copied it into the same place in our PHP code where the old one lived, and confirmed that the new key carries identical permissions. Despite this, no data is flowing and customers’ WhatsApp messages never reach the site. What I need from you: • Identify why the new key is being rejected (token mismatch, endpoint change, webhook signature, etc.). • Update or refactor the Opencart–PHP code so the waboxapp API handshake succeeds agai...
