+### Submit Order Request Endpoint
+
+To submit an order request, you can use the `createOrder` method in the `Pesapal` class. You will need to construct a DTO for `PesapalOrderData` and `PesapalAddressData` as shown below.
+
+> **info** You must provide a registered `PesapalIpn`.
+
+
+```php
+use NjoguAmos\Pesapal\Enums\ISOCountryCode;
+$ipnId = PesapalIpn::latest()->first()->ipn_id;
+
+ $orderData = new PesapalOrderData(
+    id: fake()->uuid(),
+    currency: ISOCurrencyCode::KES,
+    amount: fake()->randomFloat(nbMaxDecimals: 2, min: 50, max: 500),
+    description: 'Test order',
+    callbackUrl: fake()->url(),
+    notificationId: $ipnId,
+    cancellationUrl: fake()->url(),
+    redirectMode: RedirectMode::PARENT_WINDOW,
+);
+
+// All fields are optional except either phoneNumber or emailAddress
+$billingAddress = new PesapalAddressData(
+    phoneNumber: '0700325008',
+    emailAddress: 'test@xample.com',
+    countryCode: ISOCountryCode::KE
+    firstName: 'Amos', 
+    middleName: 'Njogu'
+//    lastName: ''
+    line2: "Gil House, Nairobi, Tom Mboya Street",
+//    city: "",
+//    state: "",
+//    postalCode: "",
+//    zipCode: "",
+);
+
+$order = Pesapal::createOrder(
+    orderData: $orderData,
+    billingAddress: $billingAddress,
+);
+```
+
+If the response was successful, your response should be as follows.
+
+```php
+[
+    "order_tracking_id" => "b945e4af-80a5-4ec1-8706-e03f8332fb04",
+    "merchant_reference" => "TEST1515111119",
+    "redirect_url" => "https://cybqa.pesapal.com/pesapaliframe/PesapalIframe3/Index/?OrderTrackingId=b945e4af-80a5-4ec1-8706-e03f8332fb04",
+    "error" => null,
+    "status" => "200"
+]
+```
+
+You can now re-direct the user to the `redirect_url` to complete the payment.
+
 ## Testing
 
 > **Info** Where possible, the tests uses real [sandbox credentials](https://developer.pesapal.com/api3-demo-keys.txt), and as such the request is not mocked. This ensures the stability of the package. Where it is impossible to use real credentials, the request is mocked. Therefore you must be connected to the internet to run the some of the tests.
