Getting Your WhatsApp Number Connected to Your CRM
This article is a high-level walkthrough of how to bring a WhatsApp phone number onboard so it works inside your CRM for automated messages, replies, and workflow triggers. The actual click-by-click screens are documented by Meta and in your CRM's in-app Help Center — we link to those at each step rather than duplicating them here. Symphony Core handles most of the technical work; this article explains what you need to provide and decide along the way.
1. Before You Start
Read WhatsApp Business API vs. the Device App first. It explains the most important rule: a phone number can be on WhatsApp or on your CRM — not both at the same time. Once you connect a number to the CRM, you lose access to that number on the WhatsApp app on your phone.
Decide which path is right for your business before we begin:
- Connect your existing business number — simplest path. You give up using that number on the WhatsApp app on your phone.
- Buy a new dedicated number — preserves the WhatsApp app on your existing number. You pay for the new line.
- Port your existing number and get a new SIM for voice — more complex; preserves voice on the existing number but moves WhatsApp identity.
Symphony Core will walk you through this decision on the kickoff call.
2. What You'll Need
To complete the setup, please have the following ready:
- A phone number to connect (existing or new — see Section 1)
- A Meta Business Manager account (business.facebook.com) — if you don't have one, you'll create it during the process
- Your legal business name (exactly as registered)
- Your business address
- Your business website URL
- A business email address
- A business category (e.g., Professional Services, Health, Retail)
- The ability to receive an SMS or voice call on the number being connected (for a one-time verification code)
If you advertise on Facebook or Instagram, you likely already have most of this set up. If not, we'll guide you through creating it.
3. The Five Steps at a Glance
Each step links to the most current official documentation. Screens change occasionally; trust the live articles over screenshots.
Step 1 — Confirm your number strategy
Pick one of the three options from Section 1 above. Tell your Symphony Core implementation contact which you've chosen.
Step 2 — Acquire a new number (if applicable)
Skip this if you're using an existing number. Otherwise: buy a local landline, mobile line, or supported VoIP number that can receive SMS or voice calls. We'll advise you on what to buy based on your country and use case.
Step 3 — Set up or verify your Meta Business Manager
If you don't have one, create it at business.facebook.com. Meta will ask you to verify your business identity (typically with a utility bill or business license) before you can send WhatsApp messages at any meaningful volume.

You'll also add Symphony Core as a partner on your Business Manager so we can manage your WhatsApp Business Account from our side.
Step 4 — Connect the number through the CRM's Embedded Signup
Inside your CRM, you'll find a "Connect WhatsApp Number" option in Settings. This opens a Meta-hosted signup window. Sign in with your Meta account, pick your Business Manager, enter the phone number, and enter the verification code Meta sends to that number.
Your CRM's current walkthrough: in app.symphonycore.com, open the in-app Help Center (or Ask AI) and search "Connect WhatsApp".
Step 5 — Test it
Send a WhatsApp message from a personal account TO the newly connected number. It should arrive in your CRM's Conversations inbox. Reply from the CRM and confirm it lands back on the personal account. If anything fails, your Symphony Core contact will diagnose and fix it.

If any step feels unclear, ask. We've done this enough times that nothing is too small to flag.
5. Frequently Asked Questions
How long does the whole process take? 30 to 60 minutes of active work on a kickoff call, spread over 1 to 3 business days because Meta's verification runs asynchronously. Business identity verification can take longer the first time you do it (a few days to a couple of weeks in some cases).
Does my number need to be in a specific country? Most countries are supported. A few smaller regions still require an alternate setup path. We confirm support for your specific country before we begin.
Can I use a Google Voice or VoIP number? Sometimes. Meta accepts certain VoIP providers and rejects others. We verify before you purchase anything.
What if I already have WhatsApp connected to a different tool (e.g., a previous vendor)? The number needs to be released from the previous WhatsApp Business Account before it can be moved. We help you request the release via Meta support. There is no shortcut for this — only the previous account owner or Meta can release it.
Will I lose old WhatsApp message history when I connect the number? Yes. WhatsApp does not transfer history from the app to the API. Treat the connection date as a fresh start for that number. If you need to preserve specific older conversations, screenshot or export them from the app first.
What if I change my mind and want to use the number on the WhatsApp app again? You can disconnect from the CRM and re-register on the app. You'll lose all CRM-based WhatsApp automation in the process, and you'll need to repeat the onboarding if you ever want to reconnect.
Who pays Meta's WhatsApp messaging fees? You do, but they're billed through the CRM's conversation-credit system. The platform documentation has the current rates per conversation category (Marketing, Utility, Authentication, Service). Most businesses find the cost meaningful only when sending bulk Marketing campaigns; Utility and Service messages are inexpensive.
6. Next Steps After Connection
Once your number is connected and tested, Symphony Core moves on to:
- Profile setup — your business display name, logo, description, and category that recipients see in WhatsApp.
- Message template approval — pre-approved messages for any automated workflow (appointment reminders, payment reminders, follow-ups). Each template is reviewed by Meta; typical approval is 1 to 24 hours.
- Workflow wiring — connecting the approved templates to the right triggers in your CRM so messages send themselves at the right moments.
You don't need to do anything for these steps unless we ask — but feel free to ask what's happening at any point. We'll let you know when WhatsApp is fully live in your account.
