# Initiate Payment

This Section briefs about how to initiate a payment !

Foloosi's Android SDK provides easy payment collections.

You can use it on the front-end to open payment page or use the actual flow to create Payment Token

#### Step - 1 - Add Dependency

We distribute our SDK from the Maven Central Repository. To begin with this SDK opens your build.gradle file of Module:app and adds the following dependency.

```
implementation 'com.foloosi:FoloosiSDK:2.0.28'
```

#### Step - 2 - Initialize SDK

To initialize the SDK add the codes below with the merchant key (Taken from foloosi merchant panel). If you do not have a merchant key create a new one and customize the checkout page to your liking.

{% code lineNumbers="true" %}

```java
 InitData initData = new InitData();
 initData.setMerchantKey(merchantKey); //YOUR MERCHANT KEY
 initData.setCustomColor(customColor); // SDK CUSTOM COLOR

 FoloosiPay.init(this, initData);
```

{% endcode %}

#### Step - **3** - Implement Payment Listener

Set and Implement our payment listener to receive payment results for every payment.

{% code lineNumbers="true" %}

```java
//Setting payment listener (paste this line after init() method)
FoloosiPay.setPaymentListener(this);
```

{% endcode %}

**Important Note** - You can Follow any one of the methods below to initiate payment widget.

### a. Make Payments via order object

####  Create Order Data Object with Necessary Inputs

You can create the OrderData or payment input with our OrderData Model class. Here you need to provide order id, title, description, currency code, order amount and customer details like name, email and mobile number.

{% code lineNumbers="true" %}

```java
OrderData orderData = new OrderData(); // Foloosi Order Data Model Class Instance
orderData.setOrderAmount(Double.parseDouble(amount)); // in double format ##,###.##
Random rand = new Random();
int orderId = rand.nextInt(100000);
orderData.setOrderId(String.valueOf(orderId)); // unique order id. 
orderData.setOrderDescription("Mobile Phone");  // any description.
orderData.setCurrencyCode(currencyCode);
orderData.setCustomerUniqueReference(""); //Customer Unique Reference value should be email/mobile no/uniqueCustomer id from your DB
Customer customer = new Customer();
customer.setName("name");
customer.setEmail("email@gmail.com");
customer.setMobile("1234567890");
orderData.setCustomer(customer);
```

{% endcode %}

#### \*Important Note\*

orderData.setCustomerUniqueReference("") value **MUST** be customer id/email/mobile number for saved card feature.

Now make payments with order data you created above.

```
 FoloosiPay.makePayment(orderData);
```
