Rave PHP SDK 😉

Class documentation can be found here https://flutterwave.github.io/Flutterwave-Rave-PHP-SDK/packages/Default.html

Use this library to integrate your PHP app to Rave.

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.

The vendor folder is committed into the project to allow easy installation for those who do not have composer installed. It is recommended to update the project dependencies using;

$ composer install

Sample implementation

In this implementation, we are expecting a form encoded POST request to this script. The request will contain the following parameters.

• payment_method Can be card, account, both
• description Your transaction description
• logo Your logo url
• title Your transaction title
• country Your transaction country
• currency Your transaction currency
• email Your customer's email
• firstname Your customer's firstname
• lastname Your customer's lastname
• phonenumber Your customer's phonenumber
• pay_button_text The payment button text you prefer
• ref Your transaction reference. It must be unique per transaction. By default, the Rave class generates a unique transaction reference for each transaction. Pass this parameter only if you uncommented the related section in the script below.

You can also find the class documentation in the docs folder. There you will find documentation for the Rave class and the EventHandlerInterface.

Enjoy... ✌️

ToDo

• Write Unit Test
• Support Direct Charges
• Support Tokenized payment
