## Requirements
1. Flutterwave for business [API Keys](https://developer.flutterwave.com/docs/integration-guides/authentication)
2. Acceptable PHP versions: >= 7.4.0. for older versions of PHP use the [Legacy Branch]( https://github.com/Flutterwave/PHP-v3/tree/legacy )
## Installation
### Download Release Artifact
If you do not want to make use of composer. each [release](https://github.com/Flutterwave/PHP-v3/releases/) contains a zip with all the dependencies installed. Simply download the one that supports your php version.
### Installation via Composer.
To install the package via Composer, run the following command.
```shell
composer require flutterwavedev/flutterwave-v3
```
## Initialization
Create a .env file and follow the format of the `.env.example` file
Save your PUBLIC_KEY, SECRET_KEY, ENV in the `.env` file
```bash
cp .env.example .env
```
Your `.env` file should look this.
```env
FLW_PUBLIC_KEY=FLWSECK_TEST-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-X
FLW_SECRET_KEY=FLWPUBK_TEST-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-X
FLW_ENCRYPTION_KEY=FLWSECK_XXXXXXXXXXXXXXXX
FLW_ENV='staging/production'
FLW_LOG_DIR=logs
```
### Render Payment Modal
The SDK provides two easy methods of making collections via the famous payment modal. [Learn more](#)
1. [Flutterwave Inline]( https://developer.flutterwave.com/docs/collecting-payments/inline )
2. [Flutterwave Standard]( https://developer.flutterwave.com/docs/collecting-payments/standard )
### Get Started
Edit the `paymentForm.php` and `processPayment.php` files to suit your purpose. Both files are well documented.
Simply redirect to the `paymentForm.php` file on your browser to process a payment.
In this implementation, we are expecting a form encoded POST request to this script.
The request will contain the following parameters.
```json
{
"amount": "The amount required to be charged. (*)",
"currency": "The currency to charge in. (*)",
"first_name": "The first name of the customer. (*)",
"last_name" : "The last name of the customer. (*)",
"email": "The customers email address. (*)",
"phone_number": "The customer's phone number. (Optional).",
"success_url": "The url to redirect customer to after successful payment.",
"failure_url": "The url to redirect customer to after a failed payment.",
"tx_ref":"The unique transaction identifier. if ommited the apiclient would generate one"
}
```
The script in `paymentProcess.php` handles the request data via the `PaymentController`. If you are using a Framework like Laravel or CodeIgniter you might want to take a look at the [PaymentController](#)
```php
getMessage();
}
if ($_SERVER["REQUEST_METHOD"] === "POST") {
$request = $_REQUEST;
$request['redirect_url'] = $_SERVER['HTTP_ORIGIN'] . $_SERVER['REQUEST_URI'];
try {
$controller->process( $request );
} catch(\Exception $e) {
echo $e->getMessage();
}
}
$request = $_GET;
# Confirming Payment.
if(isset($request['tx_ref'])) {
$controller->callback( $request );
} else {
}
exit();
```
### Configuration settings
Create a .env file and add the bootstrap method first before initiating a charge.
```php
use \Flutterwave\Flutterwave;
# normal configuration
Flutterwave::bootstrap(); # this will use the default configuration set in .env
```
if you do not wish to use a .env, you can simply pass your API keys like the example below.
```php
use \Flutterwave\Helper\Config;
$myConfig = Config::setUp(
'FLWSECK_TEST-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-X',
'FLWPUBK_TEST-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-X',
'FLWSECK_XXXXXXXXXXXXXXXX',
'staging'
);
Flutterwave::bootstrap($myConfig);
````

## Testing
All of the SDK's tests are written with PHP's ```phpunit``` module. The tests currently test:
```Account```,
```Card```,
```Transfer```,
```Preauth```,
```Collection Subaccount```,
```Payout Subaccount```,
```Subscriptions``` and
```Paymentplan```
They can be run like so:
```sh
phpunit
```
>**NOTE:** If the test fails for creating a subaccount, just change the ```account_number``` ```account_bank``` and ```businesss_email``` to something different
>**NOTE:** The test may fail for account validation - ``` Pending OTP validation``` depending on whether the service is down or not
