## Overview

The **submerchant** feature enables a Parent Merchant (Fintech or PSP) to **manage multiple submerchants**. It ensures that transactions are correctly attributed to each submerchant and facilitates granular compliance management.

## How it works

Available via API, merchants will only need an API key to list, create and update submerchants.

1. **Create an API key**
2. **Create submerchant via API**
3. **Add SubmerchantId for Payment and Transfer transactions**
4. **Track payments from the dashboard or through webhooks associated with the payment.**

## Key Advantages

* **Risk Mitigation**: You can block a single submerchant without impacting the others, reducing the risk of an entire platform being blocked due to one bad actor.
* **Granular Control**: You gain the ability to view and follow the status of each submerchant individually.
* **Traceability**: All operations are scoped, and every transaction is tagged with a `sub_merchant_id`, ensuring detailed logs and traceability via APIs and the dashboard.
