No campaign goes out without a connected number. The WhatsApp Connection page links your business number to SendFast through your Meta account: it is the number that shows as the sender of your messages. Each SendFast account works with one number. For Loja Bem Viver, it is the store's business number, the one customers already have saved on their phones.
Who can connect
The page only shows in the menu for people with the Admin role. A Member creates contacts, templates and campaigns as usual, but does not see or change the connection.
Pick the right path
Open WhatsApp Connection. With no number connected, the screen shows two buttons:
- Continue with Facebook — for a number not yet in use in the WhatsApp Business app on a phone.
- I already use this number on WhatsApp Business — for the number you already use in the WhatsApp Business app. It stays in the app: customer replies keep arriving on the phone, as before, and campaigns start going out through SendFast. It requires the WhatsApp Business app version 2.24.17 or newer.
This choice matters. Camila serves Loja Bem Viver through the WhatsApp Business app on her phone, so she uses the second button — she keeps chatting with customers in the app and sends campaigns through SendFast.
Both buttons open a Meta window. Follow its steps to the end, choosing your business and the number. Closing the window halfway changes nothing; just click again.
If you chose "I already use this number on WhatsApp Business"
During the process, a message from Meta arrives in the phone app with a button to confirm the connection. When it is done, you see "Number connected. Keep the WhatsApp Business app open for a few minutes to finish syncing." — do keep it open, with the phone online.
The page gets the Number also on the WhatsApp Business app panel, with the progress: Syncing with the app, then Synced with the app. If you chose not to share the chat history in the Meta window, it shows History not shared — that does not stop you from sending campaigns.
If syncing does not finish in time, the screen tells you. In that case Meta requires connecting again: click Disconnect and connect once more with the I already use this number on WhatsApp Business button.
Account connected, phone number pending
Sometimes the Meta window ends with no number chosen. The screen shows Account connected, phone number pending and the Add phone number button, which opens the window again so you can finish. While the number is pending, no campaign can be sent.
The connected number card
Once the number is linked, the page shows the Connected number card, with the Connected badge and four details:
- Number — the connected phone.
- Verified name — the name Meta approved to show to your customers.
- Quality — High, Medium, Low or Unknown. It is Meta's assessment of how recipients receive your messages. Low quality blocks campaign sending, so keep an eye on it.
- Sending limit — how many different people the number can message every 24 hours: from 50 recipients/day to 100,000 recipients/day, or Unlimited. Meta sets it, and it usually grows with use and good quality.
The Sync button fetches these details from Meta again. Use it when you know something changed on Meta's side — the name was approved or the limit went up, for example — and you want to see it now.
When the number is connected (and when it comes back after a drop), the account owner receives an email about it.
Disconnecting
The Disconnect button asks for confirmation. When you disconnect:
- SendFast stops sending from that number, and campaigns that were sending are paused;
- contacts and templates are not deleted;
- the account owner receives an email with the disconnection and who did it.
If the number is also used in the WhatsApp Business app, disconnecting here only stops SendFast's sends. To take the number off Meta's platform for good, use the app itself: Settings › Account › Business Platform › Disconnect.
Where to go next
- Drops and reconnection — what each disconnection warning means and how to send again.
- Click tracking — set up on this same page, to know who clicked link buttons.
- Templates — the next step: the message templates Meta approves.
- Dashboard — the Number health panel follows quality and limit over time.
In short: in WhatsApp Connection, use Continue with Facebook for a new number or I already use this number on WhatsApp Business to keep the phone app, finish the Meta window, check quality and limit on the number card, and remember that disconnecting pauses campaigns being sent but does not delete contacts or templates.
