## Key Participants

Before we get into the technical details, every card transaction involves a few core participants:

<CardGroup>
  <Card title="Cardholder" icon="user">
    The individual who owns a payment card and uses it to make purchases online or in person. They initiate the payment process.
  </Card>

  <Card title="Merchant" icon="store">
    The business or service provider that sells goods or services and accepts payments through our gateway.
  </Card>

  <Card title="Payment Gateway" icon="server">
    The technology platform that securely transmits transaction data between the merchant, acquirer, card scheme, and issuer. It acts as a bridge in the online payment process.
  </Card>

  <Card title="Acquirer" icon="building-columns">
    The financial institution or processor that enables merchants to accept card payments and routes transactions to the appropriate card schemes.
  </Card>

  <Card title="Card Scheme" icon="credit-card">
    The global network (e.g., Visa, Mastercard) that facilitates communication and transaction processing between issuers and acquirers.
  </Card>

  <Card title="Issuer" icon="building-columns">
    The bank or financial institution that issues the payment card to the cardholder and authorizes transactions on their behalf.
  </Card>
</CardGroup>

> These participants are connected through defined relationships. The issuer gives cards to customers. The acquirer allows merchants to accept card payments. Card schemes ensure secure communication between all parties.

## Our Role as a Payment Facilitator

We act as a **payment facilitator**, meaning we streamline the payment process by providing merchants with a single point of integration and managing the end-to-end transaction lifecycle.

This includes:

<CardGroup>
  <Card title="Direct Merchant Integration" icon="puzzle-piece">
    Merchants connect directly to our platform using our Hosted Payment Page, REST APIs, or ready-made plugins for platforms like WooCommerce and Magento. No need to integrate with third-party gateways or processors.
  </Card>

  <Card title="Simplified Transaction Handling" icon="brain-circuit">
    We take care of the entire transaction flow, including customer authentication, payment authorization, and securely routing transactions to the appropriate card networks and acquirers.
  </Card>

  <Card title="Acquirer Connectivity" icon="building-columns">
    Once a transaction is authorized, we handle the communication with the acquiring banks to ensure funds are settled correctly and efficiently into the merchant's account.
  </Card>

  <Card title="Built-in Security & Risk Management" icon="lock">
    Our platform includes advanced security features such as 3D Secure authentication, customizable risk rules, and real-time fraud detection to protect both merchants and cardholders.
  </Card>
</CardGroup>

> Merchants don't need to integrate with third-party gateways or processors — our platform handles everything from transaction initiation to settlement.

## Payment Flow

Let’s look at a typical payment flow when a customer makes a purchase using a card. This process includes authentication (if required), authorization, and confirmation of payment.

<img src="https://mintcdn.com/dasdoc/NIfdTDr2rgRx_fiM/images/flows-introPayment-02.svg?fit=max&auto=format&n=NIfdTDr2rgRx_fiM&q=85&s=02ea94c8bf2f9aa8005ee252166d0883" alt="Payment Flow" width="1997" height="1106" data-path="images/flows-introPayment-02.svg" />

You can integrate this flow using our:

* **Hosted Payment Page (HPP)**
* **Server-to-Server APIs**
* **Plugin-based integrations** (WooCommerce, Magento, OpenCart)

<Note>
  For a complete overview, please visit our [Online Payment](/documentation/payments/onlinepayment) section.
</Note>

A typical payment journey with our platform:

1. Customer selects a product or service.
2. Merchant initiates the payment using our API or Hosted Payment Page.
3. We securely receive and validate the card details.
4. We route the transaction to the appropriate acquirer via the card network.
5. The issuer checks and authorizes the transaction.
6. The result is returned back to the merchant through us in real time.

Each of these methods ensures secure transmission of card data, 3D Secure support, and real-time feedback for transaction approvals or declines.

## Settlement Flow

Once a transaction is successfully authorized, the merchant needs to receive the funds. Here's how the settlement process works through our platform:

<img src="https://mintcdn.com/dasdoc/NIfdTDr2rgRx_fiM/images/flows-introPayment-03.svg?fit=max&auto=format&n=NIfdTDr2rgRx_fiM&q=85&s=fdd343e17dfdeab3228b90b828a1c83f" alt="Settlement Flow" width="1997" height="1106" data-path="images/flows-introPayment-03.svg" />

1. We batch captured transactions and send them to the acquirer.
2. The acquirer clears them through the card network.
3. The issuer releases the funds to the acquirer.
4. The acquirer settles the net amount to us.
5. We disburse the merchant’s payout to their registered bank account, minus applicable fees.
