# Initiate Payment

This Section briefs about how to initiate a payment !

Foloosi's iOS 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

```
pod 'Foloosi-iOS-SDK', '~> 1.5.1'
pod update
```

### Step - 2 - Import SDK

```
import FoloosiSdk
```

### Step - 3 - Initialize SDK

To initialize the SDK - Create InitData Object with the merchant key you retrieved 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
let initData = InitData()
initData.merchantKey = "merchantKey" //"Your Unique Merchant Key"
initData.customColor = "costomColor"  // It must be valid 6 digit hexadecimal color to make payment page loading color as app color. 
FoloosiPay.initSDK(initData: initData, withDelegate: self)
```

{% endcode %}

**Important Note** 

You can Follow any one of the methods below to initiate payment widget

### a. Make Payment with order object

####  Create orderData Object with necessary inputs

You can create the order data 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" %}

```swift
let orderData = OrderData()
orderData.orderTitle = "" // Any Title
orderData.currencyCode = ""  // 3 digit currency code like "AED"
orderData.orderAmount = 0  // in double format ##,###.##
orderData.orderId = ""  // unique order id. 
orderData.orderDescription = ""  // any description.
orderData.postalCode = "00000" 
orderData.state = "Dubai"
orderData.country = "UAE"
orderData.customerUniqueReference = ""  //Customer Unique Reference value should be email/mobile no/uniqueCustomer id from your DB 
let customer = Customer()
customer.customerEmail = "email@gmail.com"
customer.customerName = "name"
customer.customerCity = "City"
customer.customerAddress = "Address"
customer.customerPhoneNumber = "1234567890"
orderData.customer = customer
```

{% endcode %}

#### \*Important Note\*

orderData.customerUniqueReference = "Unique value"

// Unique value must be customer id/email/mobile number for saved card feature. 

Now make payment with order data you created above.

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