# Connect WhatsApp Business (official API)

> Signing in with Meta, picking your number, and what the official connection unlocks.

The official connection. Unlike [the QR-code option](/help/channels/whatsapp-personal),
this does not involve a phone staying online, does not drop, and is the only way to send
templates, run broadcasts or use WhatsApp calling.

## Before you start

<Steps>
  <Step title="A phone number that is not on WhatsApp">
    The number must not currently be registered to a normal WhatsApp or WhatsApp Business
    app account. If it is, delete that account first — or
    [buy a number through us](/help/channels/whatsapp-numbers) instead.
  </Step>

  <Step title="A Meta Business account">
    You can create one during the flow if you do not have one.
  </Step>

  <Step title="Admin access to it">
    You need permission to add a WhatsApp account to that business.
  </Step>
</Steps>

## Connecting

<Steps>
  <Step title="Start the connection">
    **Settings → Channels → Add channel → WhatsApp Business**. A Meta window opens.
  </Step>

  <Step title="Sign in and follow Meta's steps">
    You will confirm your business, then create or select a WhatsApp Business account.
  </Step>

  <Step title="Verify the phone number">
    Meta sends a code by SMS or voice call to that number.
  </Step>

  <Step title="Select the number">
    Back in Linkiasoft, pick which of the numbers on that account this channel should use.
  </Step>

  <Step title="Done">
    The channel goes live. Grant it to a role so chats reach your team — see
    [Invite your team](/help/getting-started/invite-your-team).
  </Step>
</Steps>

| -------------- | ------------------------------------------------------------------------------------------------------------------ |
| **Templates**  | Import Meta's pre-approved library or submit your own. See [Template approval](/help/campaigns/template-approval). |
| **Broadcasts** | Message many customers at once. See [Broadcasts](/help/campaigns/broadcasts).                                      |
| **Calling**    | Enable WhatsApp voice calls per number, with optional forwarding and recording.                                    |
| **Stability**  | No phone dependency, no session drops.                                                                             |

## Business verification

Meta limits unverified businesses to a small number of unique customers per day. Verifying
your business with Meta lifts that. It is done in Meta's Business Manager, not here, and
it is worth starting early — it can take several days.

## Common problems

<AccordionGroup>
  <Accordion title="'This number is already registered'">
    The number is in use by a WhatsApp or WhatsApp Business app account. Delete that account
    from the app (Settings → Account → Delete my account) and wait a few minutes before
    retrying.
  </Accordion>

  <Accordion title="The verification code never arrives">
    Try the voice-call option instead of SMS. Some carriers block automated SMS. A landline
    can only use voice.
  </Accordion>

  <Accordion title="The Meta window closed before finishing">
    Nothing is saved until you complete the last step. Start again from Add channel.
  </Accordion>

  <Accordion title="I connected but no numbers are listed">
    The WhatsApp Business account has no verified number yet. Finish adding and verifying
    one in Meta Business Manager, then reconnect.
  </Accordion>
