Event triggered when [two partner accounts are merged](/help/article/merging-partner-accounts) in your partner program.

<Tip>
  When [two partner accounts are merged](/help/article/merging-partner-accounts), the `sourcePartner` account is collapsed into the
  `targetPartner` account. The source partner's enrollment in the program no
  longer exists after the merge, so any future API calls or webhook events for
  this partner will reference `targetPartner.id` instead.

  If you store partner IDs in your own system, listen to this webhook to update
  your records to use the `targetPartner.id`.
</Tip>

<WebhookResponseBodyParameters type="partner.merged">
  <ParamField body="sourcePartner" type="object">

  <ParamField body="targetAlreadyEnrolled" type="boolean">
    Whether the target partner account was already enrolled in this program
    before the merge.

    If <code>true</code>, both partners were already enrolled in the program and
    the merge process collapsed the source account into the target account.

    If <code>false</code>, only the source partner account was enrolled in the
    program, which means the partner's ID in your program was updated to the
    target partner's ID.
