# Test your wall before launch

Hosted Offerwall · For publishers · Updated 30 October 2026
Web version: https://www.affiliateos.ai/help/offerwall/test-before-launch

Open your wall as a test user on each device you support, tap through it in test mode, send a test postback, then run one real offer to the end and trace it in **Flight Recorder**. Each step checks a different link in the chain.

## Before you start

- A test user ID that no real user has, such as `test_u_48213`. Use the same one throughout.
- A postback secret and a postback URL that log `test=true` requests and don't credit them.

## Steps

### Open the wall as your test user

Open your wall's URL with your test ID in `uid` and the country you're testing in `country`. Any launch with a `uid` is a real launch, so you see what a user sees: your rewards, in your currency, for that country. If you get "This offerwall link is invalid or expired", fix that first with [these checks](https://www.affiliateos.ai/help/offerwall/link-invalid-or-expired).

### Check it on each device you support

On an iPhone the wall lists iPhone offers, on an Android phone Android offers, and on a desktop every platform. Open it where your users will: in your page's iframe, in your app's browser tab or WebView. In an iframe and a WebView, check that the close control does what you expect.

### Tap Get in test mode

Add `&testMode=1` to the URL and open an offer. **Get** records the start and keeps you on the wall instead of sending you to the advertiser, and the offer moves into the test user's **My Offers**. If you listen for [wall events](https://www.affiliateos.ai/help/offerwall/listen-for-wall-events), you receive `offer_started` with `testMode: true`.

If your account uses **Properties & Apps**, the property's **Integrations** tab has a **Test launch** button under "Verify this offerwall". It opens your wall in test mode in a new tab, for the user `property-test-user`, signed for you, so it works on walls that require signed links too.

> **Test mode doesn't create conversions.** After **Get**, test mode shows a **Complete Test Goal** button. Test goals are switched off on live walls, so it stays on "Updating..." and nothing is credited or sent. To check your crediting, use the next step.

Test mode also skips the [iPhone tracking guide](https://www.affiliateos.ai/help/offerwall/iphone-tracking-guide) sheet that opens before a new user's first **Get** (the "How tracking works" line on an offer's page still opens it). To see the sheet, add `&tracking_guide=force` and use a test ID with nothing in **My Offers**.

### Postbacks, then Send test postback

Wall conversions reach you on the postbacks you already have. Open **Postbacks**, open your saved postback and choose **Send test postback**. It's signed exactly like a real conversion and carries `test=true`: check your server verifies it, logs it and doesn't credit it.

### Run one real offer to the end

Without test mode, open the wall as your test user on your own phone and complete an offer you can finish quickly, such as installing and opening a game. This is real traffic: the click, the conversion and the postback are all real. Your postback carries `placement=offerwall`, your earnings in `revenue` and the user's reward in `user_payout`. [What your users are paid](https://www.affiliateos.ai/help/offerwall/what-users-are-paid) explains the fields.

### Check it worked

Open **Conversions** and find your test user's conversion. Then open **Reporting**, then **Flight Recorder**, to trace it from the tap to your postback. Its delivery reads `sent` or `failed`, or `skipped_no_url` when no postback URL matched. On your side, your test user should hold the reward the wall showed, converted to your currency.
