# Testing postbacks

A postback that you send with a real token creates a real conversion. It defaults to `approved` and counts in reports. Test with the tools in the Stats app first.

All three tools are on the program's **Integrations** page.

## 1. Check the endpoint

Open the **Postback endpoint** card and click **Test endpoint**. DataFlair checks two things: the program is active, and it has a postback token. When both are true, it shows "Postback endpoint is ready to receive events."

This check sends no postback and creates no conversion.

## 2. Fire a test postback

Find the **Fire test postback** form in the **Field mapping** section. Choose an approved affiliate, a conversion type (`registration`, `ftd` or `deposit`) and an amount, then send it.

DataFlair sends a synthetic postback through the real endpoint, so the token check, the validation and the duplicate check all run as they do for live traffic. If the program has a field mapping, the test postback uses your field names.

* The event is marked as a **test**. It does not earn commission.
* Its `postback_id` starts with `test-` and its `player_id` starts with `PLAYER-TEST-`.
* It shows in the **Postback log** tab, and in the **Test fires** counter.

The form appears once the program has a postback token and at least one approved affiliate.

## 3. Replay a logged postback

Open the **Postback log** tab and click a row. The **Postback detail** panel opens. When a row can be replayed, the panel has a **Replay postback** button.

A replay sends the logged request through the real endpoint again, with the program's current token. Use it after you fix a cause, such as an affiliate that was not approved yet.

* A replay is **not** a test. It processes the original event as real traffic. If the original was rejected and now passes, it creates a real conversion.
* Replaying a postback that was already accepted does nothing. DataFlair answers with the duplicate response.
* You cannot replay a test event, or a request that failed authentication.

## What to check after a test

1. The Postback log shows the request with the status you expect.
2. The response codes match the [error table](/stats/postbacks/contract#errors).
3. Sending the same `postback_id` twice gives `duplicate: true` the second time. See [Idempotency](/stats/postbacks/idempotency).
