Hello, I see you’re facing specific challenges with the Meta WhatsApp API integration in your Node.js backend and React SaaS dashboard. I have extensive experience with API integrations and have successfully tackled similar issues in the past. To resolve the embedded signup flow, I will debug the "Login with Facebook" process to ensure customer onboarding flows correctly without manual intervention. Additionally, I will examine your Meta App setup, rectify configuration issues, and ensure webhooks are functional and logging correctly. I suggest implementing thorough testing to validate the signup process thoroughly before launch. Last year, I helped a client fix similar webhook issues where we aligned app configurations, resulting in a seamless integration. I can complete this task in about 7 days. Best regards, Khurshid Ahmed

Your embedded signup flow and webhook configuration issues are classic Meta API setup problems. I'll debug the Facebook login stall, fix your app permissions and system user tokens, then rebuild the webhook endpoint to properly capture and log events. Should be straightforward once I assess your current Meta app configuration. I built a similar integration challenge with my Telegram operations bot that handles real-time API callbacks and automated system monitoring. Also created social media automation that manages OAuth flows and API token refreshes across multiple platforms. You can see more of my API integration work at ffulb.com. Available to start immediately. If you can share your Meta app credentials and current Node.js codebase, I can take a quick look at the setup and get this fixed within a few days.

Hello, I understand the critical need to stabilize your Meta WhatsApp Business API integration to ensure a smooth launch for your Node.js backend and React SaaS dashboard. I will focus my efforts first on repairing the embedded signup flow, ensuring the "Login with Facebook" process completes seamlessly without manual steps, allowing customers to onboard their WABA numbers effortlessly. Next, I will review and correct your Meta App configuration, including System User settings and access tokens, to secure proper authorization. I will then build a stable, HTTPS Express webhook endpoint to reliably receive and log every subscribed event, with visibility in the React admin panel as specified. Deliverables will include a working embedded signup with template messaging, clean app configuration stored securely with comprehensive docs, a robust webhook endpoint with 200 OK callbacks, and clear handoff scripts for ease of local testing and demo. I'm ready to dive into the Git repo and Meta sandbox once we agree, ensuring your integration is production-ready swiftly and solidly. Could you share if there are any existing logs or error messages from the failed "Login with Facebook" flow or webhook callbacks that could help diagnose the issues faster? Best regards,

@gmpaliwal21

Hi, I can fix this integration end-to-end. I’ve worked extensively with backend systems, API integrations, and webhook-based architectures, so handling Meta’s WhatsApp API flow including OAuth, app configuration, and event subscriptions is something I’m comfortable with. Based on your description, the issue seems to be a combination of an incomplete embedded signup flow, incorrect Meta app setup, and webhook misconfiguration. I can resolve the OAuth flow so onboarding works smoothly, correct the app configuration including system user and access tokens, and ensure your webhook endpoint is properly verified, receives events, and logs them reliably. I’ll also make sure the first template message is sent successfully and provide a clean environment setup along with brief documentation and testing steps. I can get this working within a few hours once I have access to the codebase and Meta developer setup. Let me know if you’d like me to get started. – Gaurav

Hi ❤️Timeline: 1–3 days||budget:20USD❤️ Meta + WhatsApp APIs… always “fun” until they work.I’ve handled these exact issues—broken embedded signup flows and silent webhooks. I’ll fix the Facebook login onboarding so users can complete WABA signup end-to-end, then clean up your Meta App setup (tokens, system user, scopes) and get the webhook reliably receiving + logging events with proper 200 responses. You’ll have a fully working flow: signup → number added → first template message sent → events visible in your dashboard. I know a 2.6⭐ review might look scary—I’ll be honest, my first project had a misunderstanding (1⭐). I learned fast, and my next projects earned 3 ✔️5⭐✔️ reviews—you can check my profile. Let’s make Meta behave

@peterj514

Hi there, I understand the pain points are blocking your launch: a stalled embedded signup and a webhook that never delivers callbacks. I’ve spent the last 4 years solving exactly this type of Meta WhatsApp API integration issues for SaaS dashboards, and I’m confident I can deliver a solid, production-ready fix. What I’ll do: (1) Repair and harden the embedded signup flow so customers can onboard their WABA numbers without manual steps, including end-to-end testing of the Login with Facebook sequence and a reliable first-template send from your interface. (2) Reconcile the Meta App configuration: correct App ID, System User, long-lived tokens, and required scopes (whatsapp_business_management & whatsapp_business_messaging). (3) Build a robust Express webhook that subscribes to the events you need, validates and logs them, and responds 200 OK to Meta; wire logs to your React admin panel. (4) Ship clean Git-committed configuration to your vault (.env / secrets manager) with updated docs describing each step. (5) Provide a concise hand-off: commands to spin up a feature branch locally, plus a Postman collection or curl scripts to demonstrate success. Deliverables: - Working embedded signup that adds a customer’s number and sends the first template message from the interface. - Clean Meta App configuration committed to your vault with updated docs. - Stable HTTPS webhook endpoint (Express) that captures sample events and returns 200 OK, with visible logging in the React admin

You’re facing onboarding and webhook issues with the Meta WhatsApp Business API that are blocking your SaaS launch. I can fix the embedded “Login with Facebook” flow so customers can add their WABA numbers seamlessly and trigger the first template message automatically. Simultaneously, I’ll configure your Meta App correctly—updating App ID, System User, long-lived tokens, and required scopes—while building a reliable Express webhook endpoint that logs all subscribed events and responds 200 OK to Meta. Deliverables include a fully working embedded signup, stable webhook endpoint visible in the React dashboard, clean Meta App configuration with documentation, and a short hand-off guide with commands and Postman/curl scripts to demo success. I have experience working with Node.js, Express, React, MongoDB, and Meta APIs, and can start immediately once Git access and the sandbox are provided.

@Rana254

You’ll receive a fully functional embedded signup, a stable HTTPS webhook, and updated documentation. Best Regards, Muhammad A.
