Pesakit is a lightweight and efficient Swift library for integrating M-Pesa mobile money services into your iOS applications. Built with simplicity and flexibility in mind, Pesakit simplifies payment initiation, transaction tracking, and error handling, allowing you to easily integrate M-Pesa functionality into your apps.

• Swift
• CompletionHandlers
• Async/Await
• MVVM (Model-View-ViewModel) architecture
• CI/CD with GitHub Actions
• SOLID & DRY principles

• Secure Authentication: Pesakit provides secure authentication using Basic Authentication(Bearer Tokens) with API key and secret, ensuring that sensitive information is protected.
• Payment Initiation: Initiate payment transactions effortlessly with just a few lines of code, enabling users to make payments for goods and services through the M-Pesa platform.
• Robust Error Handling: Pesakit includes a robust error handling mechanism that provides clear feedback on failed requests, helping developers troubleshoot and handle errors gracefully in their applications.
• Comprehensive Documentation: The library comes with comprehensive documentation, including a quick start guide, API reference, and code examples, to facilitate easy integration into iOS applications.

I am continuously working on enhancing PesaKit. Stay tuned for upcoming features, including:

• Async/Await (for efficient multithreading)
• Customer To Business Register URL(C2B) - Register URL API works hand in hand with Customer to Business (C2B) APIs and allows receiving payment notifications to your pay bill. This API enables you to register the callback URLs via which you shall receive payment notifications to your pay bill/till number.
• Business To Customer (B2C) - B2C API is an API used to make payments from a Business to Customers
• Transaction Status - Check the status of a transaction.
• Account Balance - The Account Balance API is used to request the account balance of a short code. This can be used for both B2C, Buy goods and pay bill accounts.
• Reversals - Reverses a C2B M-Pesa transaction. Once a customer pays and there is a need to reverse the transaction, the organization will use this API to reverse the amount.

To start using Pesakit, follow these steps:

• Installation:

  • In Xcode, navigate to File -> Add Package.
  • Enter the URL of the Pesakit repository: https://github.com/gichukipaul/PesaKit.
  • Choose the version or branch you want to use. Click Next and follow the prompts to complete the installation.

• Configuration and Authentication:

  • Obtain your API key and secret from the M-Pesa/Safaricom developer portal.
  • Configure authentication in the AppDelegate of the root view of your SwiftUI app by providing your credentials:

    import PesaKit
       
    WindowGroup {
           ContentView()
               .onAppear {
                   let config = PesaKitConfig(consumerKey: "yourConsumerKey", consumerSecret: "yourConsumerSecret")
                   PesaKit.configure(with: config)
               }
       }

• Usage:

  • Payment Initiation: Use Pesakit's functions to initiate payment transactions in your iOS application.
  • Once configured, you can start using the APIs provided by the library:

    import PesaKit
    
    // Example of using lipaNaMpesa method
    let paymentRequest = LipaNaMpesaPaymentRequest(/* provide necessary parameters */)
    PesaKit.getInstance().lipaNaMpesa(paymentRequest: paymentRequest) { result in
        switch result {
        case .success(let response):
            // Handle success
            print("Payment successful: \(response)")
        case .failure(let error):
            // Handle failure
            print("Payment failed: \(error)")
        }
    }

• Error Handling: Implement error handling logic to handle failed requests and unexpected responses gracefully.

• Documentation: Refer to the documentation for detailed usage instructions, code examples, and API references.

I welcome contributions from the community to help improve Pesakit. If you find any bugs, have feature requests, or want to contribute enhancements, please submit a pull request or open an issue on GitHub.

I would like to express my gratitude to Safaricom and all contributors who have played a role in making PesaKit possible.
