# Run the checks from the Operator Portal

Log in to the Operator Portal with an `operator_admin` account and open **Integration**. The **Callback test** section runs the certification checks against your sandbox wallet:

1. Save your wallet endpoint URL. For the v2 contract the URL must contain `/v2` (for example `https://wallet.operator.example/v2/wallet`). That's how the portal picks the v2 suite.
2. Create a test player with the **person_add** button. The portal creates and funds it. The player reference doubles as the launch token in the run.
3. Choose **Full suite**, set the currency and bet amount, and press **Run suite**.

The run shows every check with its pass/fail state, balance deltas, and a hint for each failure. You can replay bet and refund steps one by one. The checks are the same 55 `W2-*` checks the command-line tool runs. Six of them (`W2-D1` to `W2-D6`) test the four rules of chapter 3. You're done when every check passes.
