I have already linked our platform to the Meta WhatsApp Business Cloud API and everything tests green—except for one critical step: during doctor onboarding the verification code never reaches the handset. We rely on WhatsApp verification (not SMS or voice) and, although the request appears to succeed, no code shows up and no explicit error is returned. I have tried several phone numbers and the problem is consistent, so the root cause is somewhere in the integration or Business Manager configuration rather than with a specific device or carrier. What I need from you: • Audit the current Cloud API setup, webhook configuration, phone-number status and two-step verification settings inside Meta Business Manager. • Trace the outbound request/response cycle, confirm the message is created, and identify why the template or OTP is not delivered. • Apply any required fixes—whether that means adjusting message templates, updating phone number quality status, modifying the call to /messages, or handling rate-limit or policy issues—so the code arrives promptly every time. Acceptance is simple: when I onboard a doctor, at least three different test numbers must receive the WhatsApp verification code within seconds, with visible delivery receipts in the Meta dashboard and no manual intervention required. If you are fluent in the Meta WhatsApp Cloud API and have solved similar OTP delivery problems before, let’s get this wrapped up quickly.

Doctor onboarding needs to be instant, so having the WhatsApp verification codes fail despite a green light from the API is incredibly frustrating. It sounds like your request is hitting the Meta Cloud API successfully, but the message is likely getting dropped due to a template category mismatch or a phone number quality rating issue in your Business Manager. I can jump in to audit your webhook logs and trace the outbound request cycle to see exactly where the disconnect happens. I've dealt with these silent failures before. They usually stem from two-step verification conflicts or simple policy flags that don't trigger a standard error response. We previously built an ordering bot that managed high-volume automated confirmations, so I’m familiar with keeping delivery rates high: https://www.freelancer.com/portfolio-items/11349482-whatsapp-product-ordering-bot I'll help you get those three test numbers verified so your dashboard shows clear delivery receipts. Want a 2-min screen recording of how I'd build high-deliverability OTP workflows? Just say the word. ~ Rajesh

I can help with this, I will audit your Cloud API setup, webhook config, phone-number status, and message template — then trace the full request/response cycle to pinpoint where delivery breaks. A common culprit here: the OTP template may be stuck in a non-approved state or miscategorized as marketing instead of authentication, which silently drops messages without returning an error. Questions: 1) Is the template category set to "authentication" in your Business Manager? 2) Are webhooks receiving any delivery status callbacks at all? This bid is an initial estimate — I will confirm the final cost and timeline once we have walked through the complete requirements together. Looking forward to discussing further. Best regards, Kamran

Hi I can audit and fix your WhatsApp Cloud API OTP delivery issue from the Meta Business Manager side down to the /messages request cycle. The main technical problem here is that the API request may return successfully while the OTP message is still blocked by template approval, phone number quality, webhook event handling, two-step verification, namespace/config mismatch, or policy/rate-limit restrictions. I have experience working with Meta WhatsApp Business Cloud API, webhook debugging, template messaging, delivery receipts, access tokens, phone number status checks, and onboarding verification flows. I will review the connected WABA, phone number setup, webhook subscriptions, template category/language, OTP payload structure, and Meta dashboard delivery logs to isolate the exact failure point. Once the root cause is confirmed, I will adjust the integration or Business Manager configuration so the verification code is generated, sent, tracked, and delivered properly through WhatsApp. I will also validate the full outbound request/response path and confirm that message IDs, delivery receipts, and dashboard events are consistent. The final result will be a reliable doctor onboarding flow where multiple test numbers receive the WhatsApp verification code without manual intervention. Thanks, Hercules

Hello, I understand you already have the Meta WhatsApp Business Cloud API connected and passing basic tests, but the OTP verification message is failing during doctor onboarding despite successful API responses. The issue likely sits within template configuration, webhook handling, phone-number quality status, verification settings, or message delivery policies inside Meta Business Manager rather than the handset itself. I can systematically audit the full delivery flow to isolate the exact failure point and restore reliable WhatsApp OTP delivery. I will review the Cloud API configuration, webhook events, access permissions, phone-number status, template approval state, and outbound /messages requests to confirm whether messages are accepted, queued, or silently blocked. I’ll trace delivery receipts, inspect API payloads and error logs, apply fixes to template usage or authentication flows, and validate that OTPs are consistently delivered across multiple test numbers with proper delivery confirmation inside the Meta dashboard. I’m ready to begin immediately and can troubleshoot the integration end-to-end until onboarding works reliably without manual intervention. The final result will be a stable WhatsApp verification workflow with fast OTP delivery, verified webhook events, and a documented fix process for future maintenance. Thanks, Asif

Hi, I can help troubleshoot and fix the WhatsApp Business Cloud API OTP delivery issue so your doctor onboarding flow works reliably. I have strong experience with API integrations, webhook debugging, PHP backend flows, and WhatsApp Cloud API setup. I can audit your Meta Business Manager configuration, phone number status, webhook events, message templates, two-step verification settings, and outbound request payloads to identify why the request succeeds but the verification code is not delivered. My approach will be to trace the full request and response cycle, confirm whether the message is being created, check delivery receipts and error callbacks, validate template approval and language settings, and review rate limits, quality status, and policy restrictions. Once the issue is isolated, I will apply the required fixes in the API call, template setup, webhook handling, or Business Manager configuration. I will test with at least three numbers and confirm that codes are received quickly with visible delivery receipts in the Meta dashboard. I would be grateful for the opportunity to resolve this issue and will gladly accept any feedback you may have. Best, Justin

I can help with this, We will audit your Cloud API setup, trace the OTP request cycle, and fix delivery so codes land on every handset. The most common cause here: the message template is not approved as an "authentication" category, or the OTP parameter is not mapped correctly in the /messages call. We will verify template status, phone number quality rating, and webhook callback parsing first. A couple of quick things to confirm: 1) Is your OTP template registered under the "authentication" category in Meta Business Manager? 2) Are you sending via a custom backend or a third-party platform? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Send me a message and we can go over the details.

Hi there, I see you're dealing with an OTP delivery issue on the Meta WhatsApp Business Cloud API. Getting that working smoothly is crucial for user engagement. With around 10 years of experience in PHP and API integrations, I can help identify the bottleneck and implement a solution. It's important to ensure that your messaging system is reliable and efficient, as this directly impacts user experience. I’ve tackled similar challenges before, including a regional booking platform for a tutoring company, an internal CRM for a property agency, and a React Native field-reporting app. Let’s get this fixed so you can focus on your core functionalities. Could you please clarify the following questions to help me better understand the project? Q1: What specific error messages or issues are you experiencing with the OTP delivery? Q2: Are there any additional features or requirements you want to implement alongside fixing the OTP issue? Q3: Have you already tested the API integration with other messaging platforms, and what were the results?
