As an experienced developer with a diverse range of skills and a proven track record of successfully delivering projects, I believe I am the right person to fix your WhatsApp Firebase webhook deployment. My proficiency in backend technologies such as PHP (Laravel, CI, CakePHP, Yii) are well-suited for handling the nuances of Firebase Functions and Facebook Graph API. Furthermore, my knowledge in frontend technologies like CSS and JavaScript enable me to understand any UI aspects that may be relevant to the problem at hand. I understand the urgency of getting your business phone number live and ensuring smooth message flow. My experience in dealing with issues similar to yours - such as debugging validation handshake errors, troubleshooting URL and token mismatches, and ensuring events fire precisely - makes me confident about resolving these problems promptly. Having worked extensively with APIs and SSL certificates (which could encounter quirks during deployment), I bring a comprehensive understanding of their integration challenges. Thanks....

Hello, After reading your requirements, I understand you have a WhatsApp Business Cloud API setup on Firebase that works in test mode but fails in production due to a Facebook webhook validation issue. Because the challenge handshake is not completing, the business number cannot go live and messages are bouncing. The key need is to identify and fix the webhook URL, verify token, or Facebook app configuration, then deploy the full flow to production. I’m a developer with 5+ years of experience working with Firebase Functions, Facebook Graph API, webhook verification, SSL setup, and production deployments. In similar projects, I’ve resolved webhook validation failures, corrected App Secret Proof issues, verified real-time callbacks, and successfully moved WhatsApp integrations from test to live environments. I will diagnose the validation fault, correct any configuration mismatches, confirm that message and status events are firing in Firebase logs, and push the system live so the WhatsApp business number can send and receive messages reliably. I’d be happy to share relevant work samples in a private chat and help get this resolved quickly. Best regards, Nikita Gupta

@oleksandrf3

I NEVER USE AI FOR BIDDING! You need a pro to resolve Facebook webhook validation for your WhatsApp-on-Firebase setup, fix callback and token issues, confirm event flows, and deploy live. Sounds like just what I handle—solving production webhooks and going end-to-end with Firebase and Facebook for real-time message systems. Looking forward to discussing more details. My experience: Backend: Firebase Functions, Node.js, Express APIs: Facebook Graph API, WhatsApp Business Cloud Auth: App Secret Proof, token verification Deployment: SSL certs, webhooks, real-time event handling

@adisonw

How do you do? Thank you for the clear breakdown—this is a classic WhatsApp Cloud API production-handoff issue, and I understand exactly where things usually fail during webhook verification. I’m an experienced IT developer with hands-on work in Firebase Functions, Facebook Graph API, WhatsApp Business Cloud API, webhook validation flows, and production SSL constraints. Based on your description, the issue is almost certainly related to webhook URL registration, token echo logic, environment mismatch, or HTTPS handling during Facebook’s validation callback. I can step in quickly to: Inspect Firebase Functions (HTTP triggers) and confirm the webhook endpoint is publicly reachable and HTTPS-compliant Verify webhook configuration inside the Facebook Developer Console (URL, verify token, subscribed events) Fix challenge token echo logic so Facebook validation passes immediately Validate App Secret Proof usage and Graph API permissions Confirm real-time events (messages, delivery receipts, status updates) are firing and logged in Firebase Push the full setup to production so the WhatsApp number can send/receive messages reliably I’m comfortable working directly in live Firebase and Facebook app settings and can diagnose this efficiently without guesswork. Once complete, you’ll have a verified webhook, visible event logs, and a fully operational WhatsApp Business number in production. I can start as soon as access is granted and aim to resolve this quickly. Adison W

Hey! This is a classic WhatsApp Cloud API production cutover issue, and the symptoms you described point directly to webhook verification and environment mismatches. We’re a team of 62 professionals with over 9 years of experience working hands-on with Firebase Functions, Facebook Graph API, WhatsApp Business Cloud API, and production webhook deployments. Here’s how we can help: * Audit and fix Facebook webhook verification (URL registration, verify token, challenge echo) * Inspect Firebase Functions (HTTPS trigger, region, headers, SSL, cold starts) * Correct Facebook App + WhatsApp settings (Live mode, permissions, App Secret Proof) * Validate real-time events firing: inbound messages, delivery receipts, status updates * Push the full flow to production so the business number can send/receive messages reliably Quick questions to move fast: are you using Firebase Functions v1 or v2? Is the webhook a single endpoint or split by event type? And is the Facebook app already in Live mode with required permissions approved? Once aligned, this should be straightforward to get over the line quickly.

Dear Hiring Manager, I am ready to help get your WhatsApp-on-Firebase project live. With hands-on experience in Firebase Functions, Facebook Graph API, App Secret Proof, and SSL configuration, I can diagnose and resolve webhook validation issues quickly. My approach will include: • Reviewing and correcting the webhook URL and validation token in the Facebook Developer Console. • Debugging the Firebase Functions callback to ensure the challenge token is echoed correctly. • Testing message, status, and delivery event flows to confirm real-time updates are firing. • Deploying the fully functional system to production so your WhatsApp Business number can send and receive messages reliably. I will provide full verification and logs to demonstrate that the webhook is stable and the number operates as expected in a live environment. Kind regards,

@ahmaddar2970

Hi there, I’ve reviewed your WhatsApp-on-Firebase deployment and I’m confident I can fix the production webhook validation, verify the Facebook App settings, and enable live messaging with real-time Firebase logs. My approach: - Reproduce the verify-token flow, confirm the webhook URL in Facebook Developer Console, and ensure correct token echo and App Secret Proof handling. - Validate the SSL certificate chain and any proxy layers, then fix any URL/token mismatches causing the handshake failure. - Instrument Firebase Functions with end-to-end logs for validation, messages, status updates, and delivery receipts, plus a smoke test plan. - Deliver a smooth production deployment with a minimal downtime window and a concise post-deploy validation checklist. Questions: 1) What is the exact production webhook URL registered in Facebook, and have you seen any SSL warnings in logs? 2) Should we implement verifier token rotation, or keep the existing token? 3) Are there any proxies/CDN layers or middleware that could affect the webhook path? 4) What is your preferred production switch window, and which env vars need rotation? What is your top priority for this deployment: immediate webhook validation, stable production messaging, or full observability in Firebase? Best regards,
