# Getting Started

This guide walks you through the key tasks you will perform day-to-day: finding and reviewing transactions, and investigating cases.

***

## Navigating the platform

After logging in you will land on the main dashboard. The primary navigation on the left gives you access to:

| Section             | What it contains                                                |
| ------------------- | --------------------------------------------------------------- |
| **Transactions**    | All payment events processed by your organisation               |
| **Case Management** | Open, in-progress, and closed fraud cases                       |
| **Workflows**       | Automated detection rules (typically managed by your team lead) |
| **Lists**           | Blocklists, allowlists, and watchlists                          |

***

## Reviewing transactions

### 1. Open the Transactions list

Click **Transactions** in the left navigation. You will see a paginated list of all transactions processed by your organisation, sorted by most recent first.

*The Transactions list showing risk scores, statuses, and filter controls.*

### 2. Filter to find what you need

Use the filter bar at the top of the list to narrow down results:

* **Search** — free-text search by transaction ID, card number, or userId

### 3. Open a transaction

Click any row to open the **Transaction Detail** page. Here you will find:

* The risk score and a breakdown of all fraud flags raised
* Card, merchant, and user information
* An AI-generated insight summarising the key risk drivers
* A map showing the geographic origin of the transaction
* Related transactions from the same card or user

*Transaction detail page showing risk assessment, card info, and location.*

### 4. Take action

From the Transaction Detail page you can:

| Action          | When to use                                                                    |
| --------------- | ------------------------------------------------------------------------------ |
| **Allow**       | You have reviewed the transaction and it is legitimate                         |
| **Reject**      | The transaction is confirmed as fraudulent                                     |
| **Create Case** | Choose between allow or reject however, more investigation is needed — however |
| **Flag**        | Choose between allow or reject however, mark the transaciton as flagged        |

***

## Managing cases

### 1. Open Case Management

Click **Case Management** in the left navigation. The case list shows all cases across your organisation.

<img src="https://mintlify.s3.us-west-1.amazonaws.com/datalexsolutionsllc/images/docs/cases/cases-list.png" alt="Case List" />

*The case list with status badges, priority indicators, and assigned investigators.*

### 2. Filter and search cases

Use the filter bar to narrow by:

* **Status** — Open, Under Investigation, Resolved, Rejected
* **Priority** — Low, Medium, High, Critical
* **Date range** — cases created within a time window
* **Search** — case name, case number, or user

### 3. Claim a case

Click a case to open the **Case Detail** page. If the case is **Open** and unassigned, click **Investigate** in the action bar. This moves the case to **Under Investigation** and records you as the assigned investigator.

*Case detail page showing the overview, linked transactions, comments, and timeline.*

### 4. Review linked transactions

Switch to the **Transactions** tab within the case to see all transactions linked to this investigation. Click any transaction row to open its full detail view.

### 5. Add comments and attach evidence

Use the comments panel to leave notes for yourself and your team. You can also upload supporting files — screenshots, bank statements, or reports — directly to the case.

> Comments and attachments are disabled once a case is Resolved or Rejected. Use **Reopen Case** if you need to add more information after closing.

### 6. Close the case

Once your investigation is complete, close the case using one of the two outcomes:

| Action           | Meaning                                                     |
| ---------------- | ----------------------------------------------------------- |
| **Resolve Case** | The transaction was legitimate — case is closed as resolved |
| **Reject Case**  | The transaction was fraudulent — case is closed as rejected |

You can also use **Mark Suspicious** to flag the case for escalation without closing it, or **Reopen Case** to resume a previously closed investigation.

## Creating a case manually

Cases can be created automatically when a transaction matches a workflow rule. See the [Workflow Nodes](/docs/nodes) documentation for details.
