# Postbacks

## URL

Your Postback URL is your server endpoint that expects calls from our server. An example Postback URL might look like this: 

```
https://example.com/postback?pay={payout}&curr={currency}&tracking={tracking_id}
```

## Macros

The following macros are available and will be replaced dynamically when sending you the postback:

<table><thead><tr><th width="143">Parameter</th><th width="417">Description</th><th data-hidden></th></tr></thead><tbody><tr><td>{payout}</td><td>Publisher earnings in USD$</td><td></td></tr><tr><td>{currency}</td><td>Amount of currency awarded to user</td><td></td></tr><tr><td>{tracking_id}</td><td>Unique User Identifier</td><td></td></tr></tbody></table>

### Whitelisting

In order to ensure the integrity of the postbacks, you can whitelist our server IP. Postbacks are exclusively sent from this IP address:

```
151.106.106.155
```

### Retries

We will retry sending the postback in 1 minute intervals with a maximum of 10 tries.
