# Retrieve Webhook

## Introduction <a href="#introduction" id="introduction"></a>

We will notify you on each incoming payment to a [Proxy Wallet](https://docs.curra.io/curra-documentation/features/create-proxy-wallet) and when of assets transferred to your Omnibus accounts (Forwarding webhooks).

{% hint style="warning" %}
We will notify you up to 10 times until your server respond http <mark style="color:green;">**success**</mark> status (200-299)

We use exponential backoff with a 1-minute delay as a seed value, so it will retry at most 10 times spaced after 1 minute, 2 minutes, 4 minutes, 8 minutes, etc.
{% endhint %}

{% hint style="success" %}
In order to maintain non-custodial nature of Curra - we strongly recommend to double-check incoming webhooks via your own RPC.
{% endhint %}
