Migrating your WhatsApp number to the Official API means moving the number your customers already have saved — from the free WhatsApp Business app (or personal WhatsApp) to the WhatsApp Business Platform, run through a platform like LiveConnect, a Meta Business Partner. The number itself doesn't change, and customers notice nothing different when they text it; what changes is how your company answers: with multi-agent support, AI chatbots, a CRM for WhatsApp, and message templates, instead of a phone with the app installed.
Why companies migrate their number
Most businesses start with the WhatsApp Business app on a phone because it's free and quick to set up. The problem shows up as volume grows: a single phone can't support several agents answering at once, there's no conversation assignment, and you can't automate with bots or send campaigns with Meta-approved message templates. Migrating to the Official API solves those limits without forcing the company to abandon the number it has already built years of conversations, marketing campaigns, and printed materials around.
What happens to your chat history
This is the most common concern, and it's worth answering directly: according to Meta's policies, the conversation history that lives inside the WhatsApp Business app does not automatically carry over to the new platform. Once migration completes, that number stops working inside the app — it can't run on both systems at once — and new conversations start being logged from scratch in the chosen platform's CRM. The contacts saved on your phone are still yours, and you can message them again from the new platform, but it's worth exporting or backing up any specific conversation you need to keep (receipts, agreements, quotes) before migrating.
Requirements before migrating
- An active WhatsApp number: it can be on the WhatsApp Business app today, on personal WhatsApp, or not on WhatsApp yet at all; the exact process varies by case, but the number is preserved in all of them.
- A Meta Business Manager account: the company needs (or one is created during the process) a Meta business account that the line gets associated with.
- Business verification: depending on volume and country, Meta may require verifying the company's legal identity before or after activating the number on the API. LiveConnect walks through that step by step.
- Stop using the app with that number: once migrated, the number can no longer run on the WhatsApp Business app; all support moves to the platform.
- Availability to receive a code: Meta validates the number by sending a verification code via SMS or call at the moment of migration.
Steps to migrate your number to the Official API
- Initial diagnosis: tell LiveConnect what state your number is in today (Business app, personal, or new) and how many people will be answering.
- Sign-up in Meta Business Manager: the Meta business account that will hold the WhatsApp line gets created or linked.
- Business verification: the company's verification with Meta is completed when the case requires it, with LiveConnect supporting the documentation.
- Number migration: the transfer from the app to the API is requested; Meta sends a verification code, and once confirmed, the number goes live on the new platform.
- Operation setup: teams are created, conversation assignment rules are defined, AI chatbots are activated if applicable, and the first message templates are uploaded.
- Go live: the team starts answering from LiveConnect using the same number; customers keep texting the contact they already knew.
Total time depends on whether Meta requires additional business verification, but with the documentation ready the process is usually resolved within a few business days.
Before vs. after migrating
| Aspect | WhatsApp Business app | After migrating to the Official API |
|---|---|---|
| Number | The same | The same |
| Agents answering | 1-2, with linked phones | Several, with multi-agent support |
| Automation | No chatbots | AI chatbots 24/7 with handoff to a human |
| Bulk sends | Risk of being blocked | Meta-approved message templates |
| Contact history | On the phone, per agent | Centralized in a CRM for WhatsApp |
| Other channels | WhatsApp only | Omnichannel: Instagram, Messenger, email, web chat |
| Metrics | None | Response times and per-agent performance |
Common mistakes when migrating a number
- Not telling the team: if nobody knows the number stops working in the app, someone keeps answering from the phone while customers are already texting the platform.
- Not backing up specific conversations: receipts or agreements that only existed in the app's chat and were never saved elsewhere.
- Migrating without defining the new operation: moving the number without having set up teams, assignment rules, or chatbots leaves the company answering just like before, just without the app.
- Underestimating business verification: leaving it for the last minute when Meta does require it can delay go-live.
- Trying to use the same number in the app and the API at once: it's not compatible; you need to decide the cutover moment and communicate it in advance.
What your company gains by migrating with LiveConnect
LiveConnect is a Meta Business Partner, which means the number's activation and migration happen through an authorized process, not improvised configurations. Beyond supporting the paperwork with Meta, the team ends up operating on a platform with multi-agent support, AI chatbots, template-based campaigns, and omnichannel from day one. Plans start at USD $89/month — compare them in the pricing plans section of this same page, and see how Meta's per-conversation cost is billed in this WhatsApp API pricing guide.
If your team has already outgrown what a single phone can handle, migrating doesn't mean losing the number your customers recognize: it means adding everything the app was never able to offer. You can see in detail how the team ends up organized after migrating in this WhatsApp multi-agent guide.
