# Offerzy documentation

> Add the Offerzy offerwall to your site or app and credit your users with signed server-to-server postbacks.

Offerzy is a rewarded offerwall. Your users complete offers from our advertisers, such as reaching a level in a game, finishing a survey or trying an app, and earn your currency. You earn on every validated conversion.

An integration has three parts:

<CardGroup cols={3}>
  <Card title="Placement" icon="layer-group" href="/offerwall/placements">
    One per site or app. It holds your currency settings, your postback URL and your offerwall link.
  </Card>

  <Card title="Offerwall" icon="window-maximize" href="/offerwall/website">
    A hosted page you show in an iframe, a new tab or an in-app browser.
  </Card>

  <Card title="Postbacks" icon="server" href="/postbacks/overview">
    Signed server-to-server requests that tell you when to credit or debit a user.
  </Card>
</CardGroup>

## How a conversion works

<Steps>
  <Step title="Your user opens the offerwall">
    You pass their user ID in the offerwall link, so every conversion belongs to the right account.
  </Step>

  <Step title="They complete an offer">
    The advertiser confirms the conversion and our anti-fraud validates it.
  </Step>

  <Step title="We send you a postback">
    A signed `GET` request to your server with the user ID, the reward in your currency and a unique transaction ID.
  </Step>

  <Step title="You credit the user">
    Your server adds the reward to the user's balance. If the conversion is reversed later, a second postback tells you to take it back.
  </Step>
</Steps>

<Card title="Start with the quickstart" icon="rocket" href="/quickstart" horizontal>
  Create a placement, connect your postback endpoint and send your first test postback.
</Card>
