Migrating from WhatsApp Web to the WhatsApp Business API in 2026 is a one-way process: once a number is added to the API, it will no longer work on the WhatsApp Business app or WhatsApp Web. Migration is justified when you have more than 4-5 people handling the same number, you need AI with RAG (Real-Time Aggregator), you want automated routing, per-agent metrics, bulk templates, or CRM integration. The entire process takes 1-3 business days.
Is WhatsApp Web the same as the API?
No. They are two different things:
- WhatsApp Web. WhatsApp Business app web interface. Still relies on the primary phone and the app. Up to 4 secondary devices (5 accesses in total).
- WhatsApp Business API. Programmatic access that connects to a professional platform (not the app). Unlimited agents, AI, reports, integrations.
Migrating means leaving the app and moving the number to the API.
When is it advisable to migrate
Five clear signs:
- More than 5 people They want to handle the same number.
- You lose leads outside of business hours and you need a 24/7 AI agent.
- Your catalog has over 500 products Or do you want automatic recommendations?
- You need reports per agent to manage the team.
- Your CRM (HubSpot, Salesforce, Pipedrive) needs the conversations.
If you meet 2 or more requirements, the cost of staying on the app exceeds the cost of migrating.
What is gained and what is lost with migration
What you earn
- Unlimited agents with roles, automatic routing, individual metrics.
- AI Agent with GPT-5 + RAG on your knowledge base.
- Navigable catalog by AI (up to 9,000 products).
- Integrated scheduling with Google Calendar.
- Mass templates pre-approved by Meta for campaigns.
- Multichannel — the same team handles WhatsApp, Messenger, Instagram, and TikTok.
- Integration with CRM native.
- Reports Complete metrics: response time, conversion rate, agent satisfaction.
What you lose
- Chat on your cell phone. The number stops appearing in the WhatsApp and WhatsApp Business apps on any phone.
- Calls and video calls via WhatsApp (the API does not support calls).
- States / Stories from the number that is migrating.
If you need to keep making voice/video calls from your cell phone, a common option is to migrate a new number to the API and keep the old one in the calling app.
Step-by-step migration process
Step 1: Decide whether to migrate your current number or a new one
Migrate the current number:
- You maintain the brand history (customers already know the number).
- You lose the chat on your cell phone.
- You miss calls via WhatsApp.
Start with a new number:
- You keep the old number in the mobile app for calls and internal communication.
- You need to communicate the change to existing customers.
- Zero technical migration of the number.
For most SMEs, a new dedicated issue It's the cleanest path.
Step 2: Verify your Meta Business Manager
Before migrating, you need the verified Meta Business Manager:
- Enter business.facebook.com.
- Create or access your company's Business Manager.
- Upload the verification documents: tax receipt + proof of address.
- Wait for approval (1-5 business days).
Without verification, the limit is 250 unique recipients per 24 hours — operationally useless.
Step 3: Choose a professional platform
Aurora Inbox combines a Meta-authorized BSP, a shared inbox platform, and AI agents into a single subscription. It's the lowest-friction option for SMEs.
Step 4: Connect the number to the platform
If it's a new number: in Aurora Inbox, Connect number → Cloud API → OAuth with MetaSelect the number and authorize. It takes 10 minutes.
If it's a migration from the current number:
- Get the number from the app via Settings → Delete account in the WhatsApp Business app.
- Wait 24 hours (recommended by Meta to keep the number clean).
- Connect to Aurora Inbox via OAuth with your Meta Business Manager.
- Check via SMS or call to the number.
Step 5: Configure templates, AI agent, and tray
- Increase from 3 to 5 initial templates (welcome, reminder, confirmation, closing, after hours).
- Configure the AI agent with your knowledge base and tools.
- Create users for your team, define roles and routing rules.
Step 6: Communicate the change (if applicable)
If you migrated your current number, customers may notice. If you migrated to a new number, communicate this explicitly: in-store sign, website banner, email to your customer base.
Step 7: Go live and monitor
The first 48 hours: monitor response rate, number quality in Meta, and human scaling. Fix anything that breaks.

Frequently Asked Questions
Can I migrate my WhatsApp Web number to the API and then back again?
No. The migration is one-way. Once in the API, the number will no longer work in the mobile app.
How much does it cost to migrate?
The technical migration is free. What you pay for is the platform subscription (Aurora Inbox from $99 USD/month) and Meta's per-conversation fees.
Do I lose my history when I migrate?
Your chat history in the app is lost if you delete your account before migrating. Aurora Inbox doesn't import your old chat history—the conversation starts again.
Can my current WhatsApp Web number receive calls after migrating?
No. The API does not support calls. If you need to keep making calls, migrate a new number and leave the current one in the app.
How long does migration take?
1-3 business days if the Meta Business Manager is already verified; add 1-5 business days if the verification is new.
Do I need a programmer to migrate?
Not in Aurora Inbox. Everything is point-and-click via OAuth.
