webhook event for upsell order is not triggered

[Vikasdhakad989]

Hello Support,

  We have integrated the 'Upsell & Cross Sell - Selleasy' app to place post-upsell orders.

  We configured the 'Order creation' webhook event in our developer app.

  Upsell order is successfully placed but the webhook event for upsell order is not triggered.

  Please provide a valid solution to resolve this issue.

Thanks
