WhatsApp Business API Troubleshooting

@somendersingh96

Hello, I can help troubleshoot and fix your WhatsApp Business API setup quickly. Since your previous app under the same Business Manager was working correctly, this is most likely related to: Phone number / app linkage Missing webhook or callback configuration Messaging permissions or access token scope Business verification/payment configuration changes Template approval or messaging capability restrictions Cloud API configuration mismatch Rate limit or quality status issue I can: Fully review the current Meta/WhatsApp configuration Identify the exact root cause preventing message delivery Fix the issue and validate message sending end-to-end Document both the problem and the applied fixes clearly Verify long-term stability and proper API configuration I’ve worked with WhatsApp Cloud API, Meta Business Manager, webhook integrations, authentication flows, and messaging automation systems, so I should be able to diagnose this efficiently. From your description, I also believe this is likely a small configuration issue rather than a major rebuild. Please share: Current setup details Error responses/logs (if available) Whether you are using Cloud API or On-Prem API How messages are being triggered (API call/Postman/backend app) I can start immediately and provide a reasonable fixed-cost estimate after a quick review.

Hello, This looks like a configuration/API-state issue rather than a full rebuild, and I’ve handled similar WhatsApp Business API troubleshooting cases before. Since your previous app was already successfully sending authentication messages, the issue is likely related to one of these: • Payment/billing status sync • Phone number registration state • Token/permission mismatch • WABA linkage issue • Messaging tier/template restriction • Webhook or app configuration conflict • Meta app review/session state issue What I will do: • Review the complete WhatsApp Business API setup • Check Meta Business Manager, WABA, app permissions & phone configuration • Trace API responses and message delivery logs • Identify the exact failure point • Fix the issue and verify live message delivery • Document root cause + fixes clearly for future reference Deliverables: ✔ Working WhatsApp message delivery ✔ Full troubleshooting report ✔ Configuration/fix documentation ✔ Recommendations to avoid future failures I can start immediately and usually these types of issues are resolved quickly once the API logs and business configuration are reviewed properly. Estimated Time: A few hours depending on access and issue source. Cost: Reasonable and negotiable after initial inspection. Looking forward to helping you get the API fully operational again.

Hello, I’m Priya, with 7+ years of experience working with API integrations, Meta developer platforms, WhatsApp Business API setups, and troubleshooting production messaging workflows. From your description, this sounds less like a full configuration failure and more like a permission, token, payment status, or messaging capability issue within the second app configuration. Since the original app is still functioning, the underlying business verification and number setup are likely correct, which means the problem can probably be isolated and resolved fairly quickly. I can step in, review the complete setup, identify exactly where the message flow is breaking, document the root cause clearly, implement the fix, and provide proper notes so you understand what changed and why. I am comfortable working through Meta Business settings, app permissions, webhook configuration, access tokens, template approval states, payment settings, and API level diagnostics to pinpoint issues without disrupting the existing working application. My focus is always on structured troubleshooting rather than guessing. I prefer identifying the exact conflict, resolving it cleanly, and ensuring the setup remains stable moving forward. I would suggest we connect in chat so I can review the current configuration details, error responses and give you a realistic timeline and estimate after a quick technical assessment. Thanks and regards Priya

Rahul here, a full-stack developer with 10+ years of experience configuring and troubleshooting WhatsApp Business API setups on Meta's platform. Having a second app set up identically to a working one but silently failing to send messages is one of the most frustrating API issues to sit with, especially when everything looks correct on the surface. It is usually a missed phone number registration step, a payment method flag, or a sandbox versus live environment mismatch that is invisible until you know exactly where to look. I will come in, identify the exact issue, fix it, and document both the problem and the solution clearly so you have a full record of what went wrong and how it was resolved for future reference. Let's connect.

Hello, I have experience troubleshooting WhatsApp Business API and Meta app configurations including messaging failures token permission issues webhook problems template approval issues and payment or billing related restrictions. Since the previous app worked and the new one appears configured similarly this is likely a configuration or account level issue that can be isolated fairly quickly through systematic testing of API permissions phone number status business verification billing setup templates and message logs. I can review the full setup identify the exact failure point document the issue clearly apply the required fixes and provide a concise report of both the problem and the resolution steps for future reference. This does not sound like a major rebuild and I should be able to diagnose it quickly once I have access to the Meta and WhatsApp configuration details. Ready to discuss access timeline and estimated effort.
