Mayarin checks every payment when the buyer confirms it.

* **Clear** — Nothing. Most payments.

* **`REVIEW`** — The payment goes ahead. You are told, with the reason.

* **`BLOCKED`** — The payment is refused. The buyer sees only "This payment cannot be processed".

A `REVIEW` is a heads-up, not a rejection. The rules look for patterns such as many attempts from one address, many attempts on your account in a short window, or an amount far above your usual largest payment.

## What to do

* Look at the payment and the reason before you ship goods.

* A large first-time order flagged as an amount spike is often legitimate. Confirm with the buyer if unsure.

* `BLOCKED` payments are not created, so you have nothing to refund.

You receive a `payment.flagged` [webhook](https://help.mayarin.xyz/integrate/webhooks) for both outcomes. Buyers are never told which rule fired.
