# Disconnect Another Partner From Your WhatsApp Number

> How to remove a different BSP/platform's access to your WhatsApp Business Account before connecting it to ChatSyncs — from Meta Business Suite's Partners list, plus the extra WhatsApp Business App step required if the number is on Coexistence. Use when a customer's connection fails with an error that their number is already linked to another platform or partner.

A WhatsApp number can only have **Full access** assigned to one partner at a time. If it was
previously connected to a different BSP or automation platform, Meta blocks ChatSyncs from
connecting until that old partner's access is removed — this is the fix for the "you need to
unlink your number first" error mentioned in [Connect Account
(Embedded)](/learn/connect-whatsapp-embedded#frequently-asked).

## Remove the partner in Meta Business Suite

<Steps>
  <Step title="Open Partners">
    In [Meta Business Suite](https://business.facebook.com) Settings, go to **Users →
    Partners**. Select the partner you want to disconnect — it shows which WhatsApp account
    it currently has access to.

    </Frame>
  </Step>

  <Step title="Remove access">
    Click **Manage** next to the WhatsApp account. In the **Manage assignments** dialog, click
    **Remove access** at the bottom.

    </Frame>
  </Step>
</Steps>

**Expected result:** The old partner no longer appears with access to this WhatsApp account,
and the number is free to connect elsewhere.

<Warning>
  If the number was connected via **Cloud API only** (not Coexistence), this step alone is
  usually enough — try connecting to ChatSyncs again. If it was connected via **Coexistence**
  (the WhatsApp Business App stays active on a phone), continue to the next section — the app
  itself also remembers the old connection.
</Warning>

## If the number uses Coexistence: also disconnect from the phone

<Steps>
  <Step title="Open WhatsApp Business app settings">
    On the phone with the WhatsApp Business app, tap the **⋮** menu, then **Settings**.

  <Step title="Open Business Platform">
    Under **Your account**, tap **Business Platform**.

  </Step>

  <Step title="Tap the connected partner to disconnect">
    The currently connected partner is listed with "Tap to disconnect." Tap it and confirm.

    </Frame>
  </Step>
</Steps>

**Expected result:** The number shows no connected Business Platform partner. You can now
reconnect it — to ChatSyncs via Coexistence, if that's the path you're using.

<Tip>
  Disconnecting here only removes the old partner's API access — it doesn't affect your chats,
  contacts, or the WhatsApp Business app itself.
</Tip>

## What's next

Once the number shows no connected partner in both places, go back to [connecting your
account](/learn/connect-whatsapp-embedded) and try again.
