But internal transfer can receive webhooks.
And when i call api to resend all failed webhooks, it show messageCount: 0

Hi @d3vice are you setting up webhooks in your workspaces Notifications tab or General Settings? You can configure 2 different types of webhooks, and the webhooks in General settings will provide events for external deposits,

  1. Select Settings
    General, then scroll down to the Configure Webhook URL heading and select Manage URLs.
