# Collection Notification
Notifies the partner when funds arrive in a merchant collection account and provides the transaction and sender details needed for reconciliation.
**Notification delivery**
Pagsmile sends an HTTP `POST` request to the webhook URL configured for your integration.
**Content-Type:** `application/json; charset=UTF-8`
The notification uses the [Webhook Common envelope](https://docs.pagsmile.com/remittance-api/business/webhook/webhook-common). The fields below describe the decrypted `biz_data` object.
{% hint style="info" %}
**Requirement:** `M` = Mandatory, `O` = Optional, and `C` = Conditional. A conditional field is mandatory only when the condition stated in its description applies.
