Same number, same app
Your phone keeps working as before. Customers write to the number they already know, and you can still reply from the WhatsApp Business app when you are away from your desk.
Keep your number
WhatsApp coexistence: keep your app and number, add the API
Keep using the WhatsApp Business app on your phone while Rexenda connects the same number to the official API. Bring up to 180 days of chats with you and add AI agents and a team inbox on top.

WhatsApp Business coexistence is Meta's way of connecting one number to both the WhatsApp Business app and WhatsApp Business Platform at the same time. With Rexenda you keep chatting from your phone while your team and AI agents work from a shared inbox, and you can import up to 180 days of chat history right after connecting.
Outgrowing the app should not mean losing your number
Your customers know your number. Moving to the API used to mean giving it up or starting over on a new one.
Years of conversations live on one phone, and nobody wants to lose that history when the team grows.
The app works well on the go, but it cannot share work across a team, reply at 2 a.m. or show which chats turned into sales.
What coexistence gives you with Rexenda
Coexistence is Meta's way of linking the WhatsApp Business app and the WhatsApp Business Platform to the same number. Rexenda builds the rest on top.
Up to 180 days of history
When you connect, you can choose to bring in up to 180 days of past chats, so each customer arrives in Rexenda with context instead of a blank thread.
Contacts synced
Your WhatsApp Business app contacts are synced into Rexenda, ready to tag, assign to your team and follow up.
Replies from your phone show up too
Messages you send from the app appear in the Rexenda conversation, so your team and AI agents see the full exchange and nobody answers twice.
AI agents on your existing number
Add AI agents that answer 24/7, qualify leads, book meetings and send quotes, and hand off to a person with full context when it matters.
A team inbox instead of one phone
Several people work the same number from a shared inbox with roles and assignment, and every chat, call and quote is kept in one customer history.
Keep the app only vs. move the number to the API vs. coexistence
| App only | Number moved to the API | Coexistence with Rexenda | |
|---|---|---|---|
| Business app on your phone | Keeps working as usual | No longer used for that number | Keeps working on the same number |
| Past chats | Stay on the phone only | You start from a blank inbox | Up to 180 days imported, once, within 24 hours |
| Team and AI agents | Limited to the phone and its linked devices | Available through the platform you connect | Shared inbox and AI agents on your usual number |
| Groups and broadcast lists | Work as usual in the app | Not carried over from the app | Groups aren't synced; broadcast lists become read-only |
| What it takes from you | Answering everything from one phone | Templates outside the 24-hour window | Opening the app at least every 14 days |

Meta's rules for coexistence
- History and contacts can be synced only once, and only within 24 hours of connecting. You may also choose not to share your history at all.
- Open the WhatsApp Business app at least once every 14 days. If you do not, Meta disconnects coexistence for that number.
- The app can be linked to only one platform at a time. Rexenda does not charge per message; Meta bills its fees directly to your WhatsApp Business Account.
WhatsApp coexistence: frequently asked questions
What is WhatsApp coexistence?
WhatsApp coexistence lets you use the WhatsApp Business app and the WhatsApp Business Platform (API) on the same phone number at the same time. You keep chatting from your phone, while a platform like Rexenda adds a shared team inbox, AI agents and a CRM to that same number. Meta sets the rules and decides where it is available.
Will I lose my WhatsApp chats if I connect to the API?
No, not with coexistence. Your chats stay in the WhatsApp Business app on your phone. You can also import up to 180 days of history into Rexenda, but Meta only lets you request that sync once, within 24 hours of connecting. If you prefer, you can decline to share your history and start fresh in Rexenda.
Do I need a new phone number to use the WhatsApp API?
Not if coexistence is available for your number. You connect the number you already use in the WhatsApp Business app, and customers keep writing to it as before. If coexistence is not available for that number, you can still connect a different number to the API through Meta's Embedded Signup in Rexenda.
What happens if I don't open the WhatsApp Business app for 14 days?
Meta disconnects coexistence for that number. To keep it active, open the WhatsApp Business app on your phone at least once every 14 days. If your team mostly works from Rexenda, set a recurring reminder so someone opens the phone app regularly and the link between the app and the API stays in place.
Is WhatsApp coexistence available in my country?
It depends on Meta, which decides availability for each number. You do not need to check in advance: when you connect through Meta's Embedded Signup in Rexenda, the option to keep your WhatsApp Business app appears if your number qualifies. If it does not, you can connect another number to the API and still use AI agents and the team inbox.
