The 24-hour customer service window breaks most n8n WhatsApp flows in production. Templates test fine, then get rejected at runtime because the session had already expired while the automation was queuing. That's usually the first thing to check when someone reports intermittent send failures. My approach: map which flows are stalling and why before changing anything. Webhook misconfiguration, template format issues, and expired sessions cover most cases. Fix those first, then build or extend whatever automation you need. What you'd get in 3 days: - Diagnosis on any currently broken flows - Fix and validate (webhook verification, template approvals, auth handling) - One new n8n flow built to your spec if needed - Handoff notes on the configuration settings that aren't obvious 11,000 INR, single milestone, released on delivery. Is this Cloud API direct or routed through a BSP? And which flows are currently giving you trouble?

I start by auditing your current M-eta Developer + Whats-App Business setup end-to-end (Business Manager, WABA, app configuration, tokens, permissions, and webhook flow). Then I isolate the exact break point in the API chain whether it’s authentication (access token), Graph API permissions, webhook validation, or message template restrictions. After diagnosis, I rebuild a stable Whats-App Cloud API integration using proper architecture: secure token handling (system/user tokens with refresh strategy), webhook event processing, and clean API routing for n8n or your backend. I ensure the full flow is tested end-to-end (send → receive → delivery → logs). Once stable, I optimize for production use: template approvals, rate limits, retry handling, and compliance with M-eta policies. I also document everything so your team can manage tokens, campaigns, and debugging without dependency issues. For ongoing support, I stay available for API issues, webhook debugging, campaign failures, and Meta-related updates. I’ve worked on Graph API integrations, webhook systems, and automation pipelines with Whats-App style messaging flows. Best Regards, Usama H

Hello, I can see the real pain here isn’t just WhatsApp API setup , it’s the hidden chain between Meta access, token stability, webhook reliability, and n8n campaign flow. That’s exactly the kind of integration problem I solve. I’ve worked on API Integration and debugging flows where authentication, Graph API permissions, webhooks, and delivery checks all have to align cleanly. For your WhatsApp Business API and Meta setup, I’d first isolate the platform issue, verify the token and permissions path, then connect the event flow so your campaigns run end-to-end with fewer moving parts. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I can also help structure this for reliable ongoing Technical Support through n8n so future updates are easier to manage. Can you share whether the current blocker is token generation, webhook verification, or message delivery in n8n? Best regards, Asad

I noticed you already have a WhatsApp Business number in India and want campaigns to run directly through n8n instead of relying on Interakt long term. I can audit your Meta Developer app, WABA setup, permissions, access tokens, Graph API calls, webhooks, template status, and then connect/test the full n8n sending flow end-to-end. I recently set up an n8n workflow processing 5k+ submissions/day with rule-based routing and Slack alerts, so token handling, webhooks, and production automation are familiar territory for me. One key question: is your Meta Business Manager already verified and linked to the Indian WhatsApp number, or is the blocker happening before WABA/API access is approved? If you share current error screenshots and Meta app/WABA status, I can start with a quick diagnostic call and then open the first milestone for setup and troubleshooting.

I reviewed your project details, and it's clear you want robust, independent ecosystems. Avoiding expensive third-party wrappers like interakt by routing your campaigns natively through n8n is a smart, cost effective, long term strategy. i see that your immediate hurdle is with the Meta devolper platform setup. specially around access tokens, permissions, and connectivity.

Hello, I'm currently working on two automation and communication platforms where WhatsApp API integrations, webhook handling, campaign workflows, CRM connectivity, and automated messaging are core parts of the system. One project has already been delivered, and another is actively in development, so I'm very familiar with the challenges around Meta Business Manager, Cloud API setup, token management, and delivery troubleshooting. I'm new on Freelancer, but I have 6+ years of experience in API integrations, automation platforms, CRM systems, web applications, and workflow automation. Your requirement is exactly the type of work I handle regularly. I can help diagnose Meta Developer Platform issues, configure WhatsApp Cloud API, validate access tokens, set up Graph API connections, configure webhooks, troubleshoot messaging failures, and ensure your n8n workflows operate reliably end-to-end. I can also assist with template approvals, compliance guidance, campaign best practices, and future integrations. My preference is to first review the current setup, identify the bottlenecks, and resolve the production issues before discussing long-term support. I'd be happy to connect and review your existing Meta and WhatsApp configuration. Regards, Sugam

Hi, I can help with this as a focused WhatsApp Business Cloud API / Meta Developer troubleshooting milestone. My first step would be to review the current Meta app, WhatsApp Business Account connection, access-token setup, Graph API permissions, webhook configuration and the n8n flow that should send approved WhatsApp messages. The goal is to identify the exact blocker, validate one compliant end-to-end test message, and document the working setup plus any remaining Meta approval steps. I only work with official WhatsApp Business Platform APIs, approved templates, compliant opt-in messaging and authorized business access. I do not build scraping, spam, fake engagement, unauthorized account actions or workflows that store production credentials in project files. For this first milestone I can diagnose and resolve the initial setup issue, then quote any ongoing support as a separate small milestone once the blocker is clear. Questions before starting: 1. Is the WhatsApp Business Account already connected to the Meta app? 2. Are you using WhatsApp Cloud API directly or Interakt temporarily? 3. What exact error appears in n8n or Graph API? 4. Do you already have approved templates and opt-in test contacts?
