My existing project already calls the WhatsApp Cloud API, yet the integration fails somewhere between authentication, message flow, and error handling. I need the entire connection reviewed, debugged, and brought to a point where messages consistently travel both ways without unexpected errors. You’ll start by analysing the current configuration in Meta-developer settings, the webhook setup, and the code that hits the Graph endpoints. Once the root cause is clear, update the code, regenerate any access tokens if necessary, and document the exact steps so I can reproduce the setup on a fresh environment. Deliverables • Corrected, working integration that reliably sends and receives messages through the WhatsApp Cloud API • Clean, commented code or patch notes highlighting every change made • A short, step-by-step guide that covers environment variables, webhook verification, token refresh, and basic testing through Postman or curl When the final test message appears in my WhatsApp inbox and outbound messages show up in the Meta dashboard without errors, the job is done.

Hey, I can deploy your Node.js app on Hostinger Business hosting and fully debug the WhatsApp Cloud API integration. With 5+ years of experience in Node.js, API integrations, webhooks, and server setups, I’ll review Meta settings, fix authentication/message flow issues, and ensure reliable two-way messaging. I’ll also provide clean documentation for reproduction. Final price will be discussed after review. Best regards, Ishu

hi, I can fully review and debug your WhatsApp Cloud API integration, covering Meta developer settings, webhook verification, authentication, and message flow. I’ll identify the exact point of failure, fix token or permission issues if needed, and ensure messages are reliably sent and received through the Graph API. You’ll receive clean, commented code (or patch notes) plus a clear step-by-step guide covering environment variables, webhook setup, token handling, and testing with Postman or curl. My goal is to leave you with a stable integration that you can easily reproduce on a fresh environment.

I can review and stabilize your existing WhatsApp Cloud API integration so that authentication, webhooks, and message flow work reliably in both directions. I’ll start by auditing your Meta developer configuration, webhook verification, access tokens, and the code calling the Graph API. Once the failure point is identified, I’ll apply targeted fixes, regenerate tokens if needed, and verify the full send/receive flow end-to-end. All changes will be documented, and I’ll provide a concise step-by-step guide so you can reproduce the setup on a fresh environment without guesswork.

Hi there, I understand the frustration of having a WhatsApp integration that "almost" works but fails in production. Authentication issues and Webhook inconsistencies are common when the Graph API handshake or token lifecycles aren't perfectly aligned. My Approach to Fix Your Integration: Meta Configuration Audit: I will verify your App Dashboard settings, ensuring the Webhook is correctly subscribed to messages and the Permanent System User Token is properly generated. Code & Logic Review: I’ll debug your Graph endpoint calls and payload structures to ensure they meet the latest API version requirements. Bidirectional Flow: I will fix the Webhook listener to handle incoming messages/statuses and ensure error handling is robust enough to log specific Meta error codes. Documentation: I will provide the step-by-step guide you requested, including the Postman collection for your environment. Deliverables: A fully stable, bi-directional messaging system. Cleaned-up code with clear comments on the fixes. The "Fresh Environment" setup guide (Tokens, Webhooks, Env Vars). I have extensive experience working with Meta’s Graph API and Node.js/Python/PHP integrations. I can start by reviewing your current setup today. Would you like me to take a look at your current error logs to identify the root cause immediately? Best regards, Christian Laurian.

Hello there, This kind of issue is rarely about a single bug. When WhatsApp Cloud API breaks, somewhere in between it’s almost always a mismatch between Meta app configuration, webhook verification, and how tokens or Graph endpoints are being used in the code. I can audit your current Meta app configuration, webhook subscription, and Graph API usage, then trace message flow end to end. I’ll correct authentication, permissions, webhook verification logic, and payload handling so messages move consistently in both directions. You’ll get a fully working WhatsApp Cloud API flow, clean and commented changes, and a clear setup guide you can rely on. Looking forward to connecting and fixing this cleanly. Best Regards, Nikunj

I approach WhatsApp Cloud API issues with an engineering mindset, not guesswork. As a systems engineer and backend-oriented full stack developer, I specialize in diagnosing integrations where authentication, webhooks, message flow, and error handling intersect. My first step would be to map the full message lifecycle: Meta developer configuration, webhook verification, token validity, API request/response handling, and final message delivery. From there, I isolate the failure point, correct the configuration or code, regenerate tokens if required, and stabilize both inbound and outbound messaging so behavior is consistent and predictable. What differentiates me is experience working on production-grade integrations where clarity and reliability matter. I don’t just “make it work”; I deliver clean, commented code and clear documentation that explains every change, including webhook validation, token refresh steps, and testing with Postman or curl. This ensures you’re not dependent on me later to maintain or extend the setup. With a strong background in Node.js, JavaScript, API debugging, and structured troubleshooting, I bring both technical depth and clear communication. If you want a WhatsApp Cloud integration that is robust, well-documented, and future-proof, I’m ready to start immediately.
