I’ve reviewed your issue and this is my understanding: you’re integrating a WhatsApp Cloud API–based system into an existing ERP, and you’re consistently hitting a 401 OAuth error (code 190) where Meta cannot parse or accept the access token. Your business, phone number, and templates are already verified and approved, so the failure is likely related to token type, permission scope, system user mapping, or Business Manager configuration, not basic setup. I have hands-on, production experience debugging Meta Graph API and WhatsApp Cloud API integrations, specifically around OAuth flows, access token lifecycle issues, system user vs user token confusion, app–business linking, webhook validation, and message send/receive failures. I don’t just suggest retries—I trace why Meta rejects a request and where the configuration breaks. I can engage immediately, work contractually, and focus purely on identifying and resolving the root cause of the OAuth failure—no fluff, no reselling, no dependency. Best Regards, Deepak

I have hands-on experience integrating and troubleshooting WhatsApp Cloud API with ERP systems using PHP (PDO), MySQL, and webhooks. I’ve resolved OAuth 401 / error 190 issues involving invalid or misconfigured tokens, System User vs User tokens, permission scopes, and Business Manager mappings. I’ve worked on message send/receive flows, approved templates, webhook validation, and Graph API versioning issues. I focus on root-cause analysis, not trial-and-error, and clearly explain Meta-side restrictions (App Review, permissions, ownership). I work independently, prefer short, focused troubleshooting sessions, and am upfront if something isn’t possible under Meta policies.
