# Payment Web Hook

### Setup payment web hook

In order to receive payment updates you firstly need to specify the endpoint where you expect a web hook to come.

Use endpoint to create a payment webhook:\
[Create Payment Web Hook Endpoint ](https://apireference.inqud.com/#tag/payment-webhooks/operation/user_payment_create-webhook)

If **secret** is set up a special header will be passed along with every callback request:

```
X-Payload-Digest
```

The value of it is a **HmacSHA1** signature of the callback's body created using the callback secret provided by the user.
