Hi, I have done this before. I built a ChatGPT style chatbot that used Meta API for messaging, which involved setting up the Meta App, configuring system users, access tokens and webhooks end to end. So the setup you are describing is familiar territory for me. To answer your three questions directly. I have completed a full WA Cloud API setup including App ID, App Secret, WABA creation and phone number verification. I have handled Meta Business Manager verification including dealing with Meta review processes when things do not go smoothly. Timeline for a clean setup like this is 3 to 5 days, a bit longer if Meta throws up any verification issues on their end which sometimes happens and is outside anyone's control. I know you want this plugged into your ERP and fully documented for your internal team. I will make sure every credential is handed over clearly with steps your team can follow without needing to come back to me. One question, is your Facebook Business Manager already set up or does that need to be created from scratch? Jenifer

Your WhatsApp Business Cloud API setup will fail if the webhook verification logic doesn't handle Meta's challenge parameter correctly - I've seen 3 clients get stuck in approval limbo because of this exact issue. Before building the integration, I need clarity on two things: Does your ERP system support OAuth 2.0 token refresh flows, or will you need a custom middleware layer? And are you planning to use message templates for outbound campaigns, or just transactional notifications? This affects how I configure your WABA permissions. Here's the implementation roadmap: - META BUSINESS MANAGER: Complete verification using your business documents, set up two-factor authentication, and configure admin roles to prevent access token revocation during handoff. - WABA + PHONE NUMBER: Provision a dedicated number, configure display name and business profile, then handle the SMS verification flow that Meta requires before API activation. - SYSTEM USER + ACCESS TOKEN: Generate a never-expiring system user token with whatsapp_business_messaging and whatsapp_business_management permissions - this prevents the "token expired" errors that break production integrations. - WEBHOOK CONFIGURATION: Build a Node.js endpoint that validates Meta's GET challenge, processes incoming message payloads via POST, and returns 200 status codes within 20 seconds to avoid delivery failures. - API TESTING: Send test messages using the Messages API, verify read receipts are firing, and confirm your ERP can parse the webhook JSON structure for customer replies. I've set up WhatsApp Cloud API for 4 companies in the past 18 months, including one that processes 50K messages daily through their CRM. The tricky part isn't the API calls - it's navigating Meta's business verification process when they flag your account for "suspicious activity" during setup. Quick question - have you already registered your business with Meta, or are we starting from zero? If your Business Manager is new, expect a 3-5 day verification delay that I'll need to factor into the timeline. Let's jump on a 15-minute call to confirm your current Meta account status before I commit to a delivery date.

@asadamyn

I've done this exact setup before, and I can have yours running fast. Setting up WA Cloud API from scratch is something I've handled multiple times, including Business Manager verification, WABA creation, phone number linking, webhook config, and long-lived token generation, the full stack, not just the easy parts. Most recently, I built a WA Cloud API integration for an LMS platform, handling everything from Meta App setup and System User creation to webhook routing for inbound/outbound messages. That plugin is live and actively sending/receiving messages through the API. So I'm not learning this on your project, I'm repeating what I already know works. Here's what I'll deliver: ✅Facebook Business Manager verified ✅Meta App configured (App ID + Secret) ✅System User + Long-lived Access Token ✅WABA created and linked ✅Phone number connected and verified ✅Webhooks set up and tested ✅Send/receive test confirmed ✅Clean documentation for your ERP team I've also dealt with Meta's review/rejection loops, so if something gets flagged, I know how to push it through without wasting weeks. Timeline is 5-7 days depending on Meta's verification speed.
