# Validate payments

> Approve or reject checkouts awaiting manual review

## When validation is needed

For **Argentina**, if an inbound transfer is not detected automatically within about 30 seconds, the payer can tap **“I already paid”** and **upload a receipt** (JPEG, PNG, WebP, or PDF, max 10 MB). The checkout moves to **`awaiting_manual_review`**.

You receive a **`checkout.awaiting_manual_review`** webhook. A badge on **Validate** in the dashboard shows how many sessions need attention.

## Open the validate view

1. Go to **Checkouts** (`/app/checkouts`).
2. Click **Validate** (top right), or open `/app/checkouts/validate`.

You see a table of checkouts in **`awaiting_manual_review`** with date, account, amount, payer, and a link to the **receipt**.

## Approve a payment

1. Click **Review** on a row.
2. Confirm amount, payer, and receipt image.
3. Click **Approve**.

HG.Cash tries to link a matching **inbound transaction** on the same account (amount, DNI from CUIL when available, time window). If exactly one candidate exists, it is linked automatically. You can also supply a transaction ID via API integrations.

On success the checkout becomes **`completed`** and **`checkout.completed`** webhook fires.

## Reject a payment

1. Open **Review**, then **Reject**.
2. Enter a **reason** (required).
3. Confirm rejection.

Status becomes **`rejected`**; payer may see rejection on the hosted page if they return. Webhook: **`checkout.rejected`**.

## Receipt download (API)

**`GET /api/v1/checkouts/{id}/receipt`** returns a short-lived signed URL for the uploaded file (merchant token with access to the checkout).

## Permissions

* **Merchants (`USER`)** can validate their own checkouts.
* **Admins** need **validate checkouts** permission (or super admin).
