Project Overview I am looking for an experienced WhatsApp Cloud API / Meta Business API developer to set up WhatsApp Cloud API from start to finish and integrate it with our existing OnTime Cabs cab-booking website. This is a complete implementation project. I need someone who can handle Meta setup → WhatsApp API → templates → webhook → backend integration → website integration → testing → production deployment → documentation and handover. WhatsApp API Setup Freelancer must handle the complete Meta setup, including: Meta Business Portfolio configuration WhatsApp Business Account WhatsApp Business phone number Meta Developer App WhatsApp Cloud API API authentication Webhook Webhook verification Message templates Template variables Production configuration All accounts/assets must remain under OnTime Cabs ownership. The freelancer should receive appropriate access to perform the work. Webhook Requirements Configure and test webhook for relevant WhatsApp events including: Sent Delivered Read Failed Incoming events where applicable Webhook events should be logged and connected with the website/backend. Website Integration WhatsApp integration must happen through our secure backend. Do NOT expose: Access tokens API secrets Database credentials Webhook secrets in frontend JavaScript or publicly accessible code. Database / Logging WhatsApp messages should be properly logged. We need to be able to track: Booking ID Customer Mobile number Message type Template name WhatsApp message ID Sent status Delivered status Read status Failed status Error information Timestamp Important Requirements Duplicate Protection If the same booking event is triggered twice, the customer should not receive duplicate messages accidentally. Error Handling If WhatsApp fails: The booking itself should NOT fail. Example: Booking created successfully ↓ WhatsApp API temporarily fails ↓ Booking remains confirmed ↓ Error is logged ↓ Admin can see the WhatsApp failure Testing Freelancer must perform complete end-to-end testing. Testing should include: Normal booking Payment confirmation Driver assignment Booking modification Booking cancellation Trip reminder Trip completion Review request Invalid WhatsApp number WhatsApp/API failure Duplicate message prevention Webhook testing Multiple booking testing Production test A final test report with screenshots/logs should be provided. Handover Requirements This is VERY important. At completion, I need complete handover of: Source code Database changes API configuration documentation Webhook documentation WhatsApp template list Template variable mapping Meta/WhatsApp configuration details Deployment instructions Testing report Troubleshooting guide Architecture diagram Required environment variables/configuration Account/access checklist The system must not depend permanently on the freelancer. Another developer should be able to maintain the integration using the documentation. Account Ownership All important accounts must remain owned by OnTime Cabs. The freelancer must NOT create the production WhatsApp/Meta assets under their personal ownership. On completion, all necessary access/configuration must be handed over to OnTime Cabs. Preferred Freelancer Skills Please apply only if you have actual experience with: WhatsApp Cloud API Meta Graph API Meta Business Manager WhatsApp Business Platform Webhooks REST APIs PHP/Node.js/Python or our existing backend technology MySQL Payment gateway integration Website backend integration Production deployment API debugging Experience with cab/taxi booking systems is a plus.

Project Type Fixed Price Project I am looking for someone who can take responsibility for the complete implementation rather than only completing one part of the integration. Please provide your best fixed price and realistic completion timeline. Important Please do not apply if you have only basic WhatsApp Business App experience. I specifically need experience with Meta WhatsApp Cloud API and website/backend integration. The project will be considered complete only after successful testing in production and complete technical handover.

Hi, I understand you need a robust WhatsApp Cloud API setup and seamless integration with your OnTime Cabs website, ensuring bookings are confirmed and customers are notified without disruption. My approach focuses on a secure, reliable, and maintainable solution. My process involves three main stages: first, configuring your Meta Business Portfolio and WhatsApp Business Account, including API authentication and message templates, ensuring all assets remain under your ownership. Second, I will implement a secure webhook on your backend to capture relevant events, log all messages with detailed tracking information, and prevent duplicate notifications. Third, I will integrate this into your website, rigorously testing all booking scenarios and failure modes, including API outages and duplicate triggers, before a full production deployment and handover. I will prioritize preventing duplicate messages and ensuring API failures do not halt your booking process, with detailed logging and a comprehensive handover package including documentation, source code, and deployment guides. This will enable your team to manage the integration independently. My experience includes integrating WhatsApp Cloud API with booking systems, specifically focusing on secure backend implementation and comprehensive error handling. Regards, Muhammad Azeem

Hi there, to ensure ride updates trigger within 5 seconds, I will utilize a Node.js microservice for low-latency webhook processing to prevent any backend bottlenecks. I will integrate the WhatsApp Cloud API for OTPs, status updates, and the chat widget while syncing real-time data with your LAMP backend. I have handled similar ride-hailing flows before and will ensure your Meta number approval and templates are configured correctly. Is your Meta Business account already verified for number approval? I can start by auditing your current API setup today to map out the sync logic. Talk soon, Saeed.

Hi, I can set up WhatsApp Cloud API end to end for OnTime Cabs, configure Meta Business, templates, and webhook, then integrate it through your secure backend with full logging and handover. All assets stay under your ownership. I can start today. For duplicate protection, I will key each send by booking ID and event type so retries never resend, and log failures without breaking the booking. Questions: 1) Is your backend PHP, Node, or Python? 2) Which templates should I draft first? Looking forward to discussing further. Regards, Shayan.

Hi, I have carefully reviewed your WhatsApp Cloud API integration requirements and can implement the complete WhatsApp communication flow into your existing cab-booking website. I can handle: * WhatsApp Cloud API configuration on Meta * Business number, templates, webhooks and access tokens * Booking confirmation notifications * Driver/ride status updates * OTP verification via WhatsApp * Secure webhook and API endpoints * Customer-support live-agent handover * WhatsApp chat integration * “Book through WhatsApp” workflow * Synchronization between WhatsApp conversations and your existing booking engine * Integration with your current booking form * Error handling, logging and API security * Git-based source code delivery * Deployment and token/template management documentation I would keep the existing booking system intact and connect WhatsApp through a clean API/webhook layer so booking data remains synchronized between the website, WhatsApp and your dashboard. For the webhook architecture, I can use your existing LAMP/PHP stack or a lightweight Node.js/Python service where it provides a cleaner and more reliable event-processing flow. I will also test the complete journey from booking → WhatsApp notification → ride status updates → OTP → support handover and document the final setup. **Estimated delivery:** 4–6 days **Availability:** Immediate Best Regards, **Ubaid Alam** Full Stack Developer | API Integration | WhatsApp Automation

Your requirement goes beyond basic WhatsApp notifications—you need WhatsApp Cloud API tightly connected to the existing cab-booking lifecycle, including booking confirmations, live ride events, OTP, agent takeover, and a complete “Book through WhatsApp” flow that syncs with your existing engine. I’d implement this with a secure WhatsApp Cloud API integration layer, keeping your LAMP application intact and using a small Node.js/Python service only where it improves webhook processing and reliability. Webhooks would handle delivery/status events, while authenticated backend endpoints trigger approved templates based on booking and ride-state changes. The WhatsApp booking flow would validate user input, create/update the existing booking record, and return status without creating a parallel booking system. Milestones: Meta Business/Cloud API + templates + webhook configuration Secure notification and OTP endpoints Live chat + agent handover WhatsApp booking flow + booking-engine synchronization End-to-end testing, deployment and documentation I’d target 2–3 weeks, depending on Meta approval/template turnaround. Two points I’d confirm first: which WhatsApp Business number do you plan to connect, and does your existing booking system expose APIs for creating/updating rides?

Hi, I'm Md Shahid Ansari, a full‑stack developer and AI engineer with 2+ years building end‑to‑end integrations. I have implemented WhatsApp Cloud API for a ride‑hailing app (booking notifications, driver assignment, payment confirmation) and for an e‑commerce platform (order status, review requests). I will use Node.js with FastAPI/Python for the webhook layer, store logs in MongoDB, and keep all tokens in environment variables on the server. I will set up Meta Business Manager, create the WhatsApp Business Account, configure the app, verify webhooks and upload approved templates, then link them to your existing backend. Idempotent keys based on booking ID will stop duplicate sends, and try‑catch with retry queues will log failures without affecting the booking flow. I estimate 1-2 days for implementation, testing and documentation. I'll includes source code, DB changes, full docs, architecture diagram and 3‑day support.
