Notification types

Webhooks are typically sent when:

  • A resource was created or updated.
  • A request was initiated (such as a payment authorisation request, a refund request, or a funds transfer request).
  • There was a fund movement (funds added to or deducted from balance accounts).

You can differentiate the events based on the type. Some notification types also include a data.status field that informs you of the outcome of the event.

balancePlatform.accountHolder.created An account holder was successfully created.
balancePlatform.accountHolder.updated An account holder was successfully updated.
balancePlatform.balanceAccount.created A balance account was successfully created.
balancePlatform.paymentInstrument.created A payment instrument was successfully created.
