Meta Expert for WhatsApp API

@HamzaBnoui

The setup itself is usually straightforward; the part that saves time later is generating the right permanent credentials and documenting the workflow so future numbers can be onboarded the same way. I’d start by completing the Meta Business Manager onboarding, verifying the connection with live send/receive tests, then provide a concise walkthrough covering template creation and API testing in Postman. If you later want automation, the same API foundation can be extended cleanly. I’ve also built a WhatsApp-focused admin dashboard concept as part of my API integration work. Are you planning to use the Meta Cloud API directly, or do you already have a BSP/provider in place?

The two spots this onboarding usually stalls: getting a truly permanent access token (most people generate a temporary 24-hour token from the Graph API Explorer and then wonder why it dies overnight — the permanent one requires creating a System User inside Business Manager, assigning it to the WhatsApp Business Account with full permissions, and generating the token from there), and getting the number bumped into a real messaging tier for marketing broadcasts (needs verified business + approved display name + one or more approved template categories before Meta stops throttling you to 250 conversations/day). I'm a full-stack dev with 9+ years, comfortable with Meta Graph API, WhatsApp Business Cloud API endpoints, and the Business Manager permissions maze. Have wired up WhatsApp API integrations before — from onboarding through template approval, webhook setup for inbound messages, and broadcast sending via Postman or a Node/Python script. What I'll deliver: complete API onboarding inside Business Manager, phone number ID + WABA ID + permanent system user token, display name registration if needed, verified "Connected" status, one sample message template submitted for approval, test message sent and received against your number, and a short PDF walkthrough covering how to add future numbers, submit templates via API, and send broadcasts via Postman collection I'll include.

Is this WhatsApp connected through the Cloud API already or still on the old on-premise setup? That changes whether I need to just verify webhooks and templates or migrate the number over first. Either way I can get it live today, this is a same-day job. Numbers here are a starting point based on the post, we'll lock final scope once I know your setup. Let me know and I'll get started.

Hello! I'll get your WhatsApp Business number fully connected to the Meta API with proper authentication, endpoint configuration, and reliable message delivery. I've handled API Integration projects that required connecting business communication platforms to Meta services, including configuring webhooks for real-time message handling and ensuring secure OAuth flows. My work in Server to Server Facebook API Integration has taught me how to navigate Meta's developer console, manage app permissions, and troubleshoot connection issues between business accounts and their APIs. I also bring Project Management experience to coordinate the technical setup with your business requirements and timeline. Here's how I'll get you there: - Verify your WhatsApp Business account credentials and configure the Meta app with proper permissions and webhook endpoints - Implement authentication flows and test message sending/receiving with error handling and retry logic - Document the integration setup and provide testing results to confirm full connectivity Are you currently seeing specific error messages during the connection process, or is this a fresh setup from the developer console? I'm ready to start immediately and can provide updates through Freelancer messages as we progress through each connection step. Best regards, Jordan Rafael G.

Hi, I see you need your WhatsApp Business number connected to the official Meta API for marketing broadcasts. Your Meta Business account is already verified and the number is active — so the remaining work is API onboarding, credential generation, and a walkthrough. My Approach: 1. Complete WhatsApp Business API onboarding inside Meta Business Manager (phone number registration, display name approval). 2. Generate permanent access token, phone number ID, and WhatsApp Business ID via Graph API. 3. Verify "Connected" status and confirm messaging limits for marketing tier. 4. Send and receive a test message to validate the setup end-to-end. 5. Deliver a concise PDF walkthrough covering template upload and broadcast sending via Postman. I've worked with the Facebook Graph API and Meta Business Manager for WhatsApp Business onboarding. Token management and 2FA setup are straightforward once the Business Manager is verified. I can start immediately and wrap up within 24-48 hours, depending on Meta's phone number registration approval time. Do you already have the WhatsApp Business Manager app created in your Meta account, or should I guide you through that first step? Best,

@vertechsolutions

Hello, I will complete your WhatsApp Business API onboarding in Meta Business Manager so your number shows as Connected with correct messaging limits and a permanent access token. I have spent the last 4 years solving exactly this type of problem. I'll authenticate with two-factor verification, retrieve the phone number ID and WhatsApp Business ID via the Facebook Graph API, generate a long-lived token, verify messaging limits, and test send/receive using Postman. I'll include a concise PDF walkthrough for uploading message templates and sending broadcasts, explaining how to structure templates for your Digital Marketing flows; the notes will be suitable for Business Consulting review, and I will run a Project Management checklist to ensure handover and repeatability. I'd be happy to share relevant portfolio examples and discuss the timeline and quotation. Best regards, syed ribal www.freelancer.com/u/vertechsolutions

I’d complete the Meta WhatsApp Business Platform onboarding, verify the existing business/phone configuration, and leave you with working API credentials and a repeatable setup process for future numbers. I’d first audit the current Meta Business Manager and WhatsApp Business Account configuration, then complete the required API setup, phone-number registration, permissions, webhook/test configuration, and credential generation. I’d verify sending and receiving through the Graph API/Postman and document template creation and API usage. The main risks are Meta permission/verification requirements and restrictions around permanent tokens or messaging limits. I’d use Meta’s current supported authentication flow and identify any account-level limitation rather than trying to bypass it. Is the number currently connected to the WhatsApp Business app or another API provider? Do you already have a Meta app created in Developers? Which CRM or sending platform, if any, will consume the API?

Hello, I can help connect your existing WhatsApp Business number to the official WhatsApp Business API through Meta Business Manager and ensure the setup is fully operational for scalable marketing and customer messaging. I am happy to offer a free consultation to review your current Meta Business configuration and confirm the number’s status before we begin. I reviewed the brief carefully, including API onboarding, generation of the Phone Number ID and WhatsApp Business Account ID, permanent access token setup, messaging-limit verification, test message validation, and the need for a simple handover guide covering message templates and API testing through Postman or a similar tool. My approach would be to complete the Cloud API configuration inside Meta Business Manager, connect and verify the existing number, configure secure token management, test both inbound and outbound messaging flows, confirm the account shows as properly connected, and provide a concise walkthrough showing how to create approved templates and send future broadcasts through the API. Looking forward to working with you and bringing your vision to life. Kind regards Andile

The bid amount and timeline above are rough placeholders , we'll sharpen both once we've had a quick look at your current setup together. Sounds like you're just a few steps away from being live. You've already done the hard part: the Meta Business account is verified and the WhatsApp number is active. What's left is finishing the API onboarding inside Business Manager, locking in a permanent system token, and making sure your number's messaging tier is set correctly for marketing-scale broadcasts. Once that's done, you'll be able to fire off template campaigns through the API or Postman without hitting walls. Here's how we'd approach this: - API onboarding: Walk through the full Meta Business Manager setup to get the phone number ID, WhatsApp Business Account ID, and a permanent (non-expiring) access token generated and secured. - Messaging limits: Verify the number is at the right tier for outbound marketing and flag anything that could throttle your campaigns early. - Token and credential handoff: Document the exact credentials you'll need, with notes on how to rotate the token safely if you ever need to. - Walkthrough: Record a short screenshare or put together a clean PDF covering template uploads, broadcast sends, and how to repeat the whole onboarding process for future numbers. - Test sign-off: Send and receive a live test message using the new credentials so you can confirm everything's working before we close out. After a short scope chat we'll put together a written proposal covering deliverables, timeline and a firm price.

Hi, WhatsApp Business API onboarding is a common bottleneck for marketing campaigns — the good news is that with your Meta Business account already verified and the number active, the hardest part is already done.

@obademio1

I will complete the WhatsApp Business API setup in Meta Business Manager and verify the connection from end to end. The goal is to have your existing number fully connected, generate the required credentials, and confirm that you can send and receive messages successfully. I will first review your Meta Business account, WhatsApp Business setup, and current API configuration. Then I'll complete the onboarding, configure the phone number ID, WhatsApp Business ID, permanent access token, verify messaging status and limits, and test the complete messaging flow. Before delivery, I'll provide a short walkthrough showing how to create message templates and send requests using the API or Postman. The main challenges are usually related to access permissions, token configuration, or business verification settings. I'll verify each step before testing so the setup is complete and ready for production use. I have worked with Meta Business Manager, the WhatsApp Business API, Graph API, access tokens, and API-based messaging integrations. Questions: 1. Are you using the Cloud API or an on-premise WhatsApp Business API setup? 2. Do you already have a Meta developer app created for this number? 3. Will the permanent access token be used directly, or through your own application or automation platform?

@enricos0

I noticed you're looking for someone to complete the API onboarding, generate the necessary IDs, and ensure your number is marked as "Connected" with the right messaging limits. Plus, a brief walkthrough on uploading message templates is exactly what I provide for my clients. As someone skilled in token management and two-factor verification, I’m here to make this happen quickly and efficiently. My commitment to speedy communication and fast turnaround is why I have returning customers. I am available for a quick chat! Regards, Enricos0

@ibcalfredo

Hi! I'd love to help. I currently have 2 numbers live on the WhatsApp Business API, so I know Meta's onboarding and Graph API inside out. Important Note: Meta doesn't allow a number to be active on both the mobile app and the API at the same time. You'll need to disconnect your current number from the app or use a dedicated new number for API automation. What I will deliver: Full Meta API Setup: Onboard your number in Meta Business Manager. Generate your Phone Number ID, WABA ID, and Permanent Access Token (System User). Ensure status is "Connected" with proper messaging limits. Templates & Walkthrough: Help you submit message templates directly in Meta Manager. Provide a quick walkthrough (screenshare or concise guide) on managing templates and sending broadcasts via Meta or Postman. Inbound Messages (Webhooks): The API sends outbound messages natively, but receiving replies requires a small 24/7 server webhook. I can forward replies to your email/WhatsApp, or build a simple web dashboard for you to send/receive messages in one clean place.
