# Webhooks

Use webhooks to be notified about events on your PushPushGo subscribers

Webhooks are an easy way to automatically communicate one app with another.\
In our application Webhooks are configured in menu [Integrations -> Webhooks.](https://app.pushpushgo.com/integrations/webhooks)

Specify what `Event` should trigger notification and define an api endpoint `Webhook Url` where we should send the request.

Webhooks are sent as POST requests, with body of type `IBody`

| IBody property name | type     | description                      |
| ------------------- | -------- | -------------------------------- |
| `projectId`         | `string` | your project identifier          |
| `customId`          | `string` | subscriber's customId if defined |
| `ppgId`             | `string` | subscriber identifier            |

{% hint style="info" %}
For every request we set an `X-PPG-Signature` header. Its value is a result of following operation:

\
We take the full JSON body and sign it using `HMAC-SHA1` with your `ProjectId` as the key.
