# Offerzy Docs

> Integrate the Offerzy offerwall: embed it on your site or in your app, credit users with signed server-to-server postbacks and get paid on Net 30 terms.

- [Offerzy documentation](https://documentation.offerzy.io/index.md): Add the Offerzy offerwall to your site or app and credit your users with signed server-to-server postbacks.
- [Quickstart](https://documentation.offerzy.io/quickstart.md): Create a placement, connect your postback endpoint, test it and put the offerwall in front of your users.
- [Placements](https://documentation.offerzy.io/offerwall/placements.md): A placement connects one site or app to Offerzy: its offerwall link, currency, postback URL and reporting.
- [Add the offerwall to your website](https://documentation.offerzy.io/offerwall/website.md): Embed the hosted offerwall in an iframe or open it in a new tab, with your user's ID in the link.
- [Add the offerwall to your app](https://documentation.offerzy.io/offerwall/mobile-apps.md): Open the hosted offerwall in an in-app browser or a WebView on Android and iOS.
- [Currency and rewards](https://documentation.offerzy.io/offerwall/currency.md): Name your currency, set its exchange rate and run reward boost events.
- [Postbacks](https://documentation.offerzy.io/postbacks/overview.md): How Offerzy tells your server to credit or debit a user, with every parameter and a complete handler in Node.js, PHP and Python.
- [Verify postbacks](https://documentation.offerzy.io/postbacks/security.md): Check the signature on every postback with your secret key, so only requests from Offerzy can credit your users.
- [Reversals](https://documentation.offerzy.io/postbacks/reversals.md): When a conversion is reversed after you credited it, a second postback tells you to take the reward back.
- [Test and monitor postbacks](https://documentation.offerzy.io/postbacks/testing.md): Send test postbacks from the dashboard, understand automatic retries and check every delivery in the Postbacks report.
- [Go-live checklist](https://documentation.offerzy.io/go-live.md): Everything to check before your users see the offerwall, so rewards are accurate and support requests stay low.
- [Offers API](https://documentation.offerzy.io/api.md): Show offers in your own interface with an API placement.
- [Payments](https://documentation.offerzy.io/payments.md): When and how you get paid: Net 30 terms, the minimum payout, payout methods and how reversals affect invoices.
- [Missing rewards](https://documentation.offerzy.io/missing-rewards.md): What to check when a user says a reward didn't arrive, and where to send them for help.
