MPESA Golang API Wrapper

The wrapper provides convenient access to the Safaricom MPESA Daraja API for applications written in server-side Golang. 🚀

Installing

You can install the package by running:

go get github.com/AndroidStudyOpenSource/mpesa-api-go

Usage

The package needs to be configured with your appKey and appSecret which can be obtained from Safaricom.

const (
	appKey = "YOUR_APP_KEY"		    
	appSecret = "YOUR_APP_SECRET"	   
)

The following examples with show you how to make requests to the various api's available.

MPESAExpress (Formerly STKPush)

This api allows you to do Lipa Na M-Pesa payment using STK Push. This is a simple example:

package main

import (
	"log"
	"github.com/AndroidStudyOpenSource/mpesa-api-go"
)

const (
	appKey    = ""
	appSecret = ""
)

func main() {

	svc, err := mpesa.New(appKey, appSecret, mpesa.SANDBOX)
	if err != nil {
		panic(err)
	}

	res, err := svc.Simulation(mpesa.Express{
		BusinessShortCode: "",
		Password:          "",
		Timestamp:         "",
		TransactionType:   "",
		Amount:            0,
		PartyA:            "",
		PartyB:            "",
		PhoneNumber:       "",
		CallBackURL:       "",
		AccountReference:  "",
		TransactionDesc:   "",
	})

	if err != nil {
		log.Println(err)
	}
	log.Println(res)

}

C2B

This api allows you to register C2B Callback URLs to Safaricom, and also Simulate a C2B Transaction in Sandbox

This is a simple demo to show how to register C2B Callback URL:

package main

import (
	"log"
	"github.com/AndroidStudyOpenSource/mpesa-api-go"
)

const (
	appKey    = ""
	appSecret = ""
)

func main() {

	svc, err := mpesa.New(appKey, appSecret, mpesa.SANDBOX)
	if err != nil {
		panic(err)
	}

	res, err := svc.C2BRegisterURL(mpesa.C2BRegisterURL{
		ShortCode:       "",
		ResponseType:    "",
		ConfirmationURL: "",
		ValidationURL:   "",
	})

	if err != nil {
		log.Println(err)
	}
	log.Println(res)

}

To simulate a C2B Request, use this simple example:

package main

import (
	"log"
	"github.com/AndroidStudyOpenSource/mpesa-api-go"
)

const (
	appKey    = ""
	appSecret = ""
)

func main() {

	svc, err := mpesa.New(appKey, appSecret, mpesa.SANDBOX)
	if err != nil {
		panic(err)
	}

	res, err := svc.C2BSimulation(mpesa.C2B{
		ShortCode:     "",
		CommandID:     "",
		Amount:        "",
		Msisdn:        "",
		BillRefNumber: "",
	})

	if err != nil {
		log.Println(err)
	}
	log.Println(res)

}

B2C

This api allows you to do M-Pesa Transaction from company to client.

package main

import (
	"log"
	"github.com/AndroidStudyOpenSource/mpesa-api-go"
)

const (
	appKey    = ""
	appSecret = ""
)

func main() {

    var initiatorPassword = ""
	svc, err := mpesa.New(appKey, appSecret, mpesa.SANDBOX)
	if err != nil {
		panic(err)
	}
    
    securityCredential, err := svc.GetSecurityCredential(initiatorPassword)
    if err != nil {
        panic(err)
    }

	res, err := svc.B2CRequest(mpesa.B2C{
		InitiatorName:      "",
		SecurityCredential: securityCredential,
		CommandID:          "",
		Amount:             0,
		PartyA:             "",
		PartyB:             "",
		Remarks:            "",
		QueueTimeOutURL:    "",
		ResultURL:          "",
		Occassion:          "",
	})

	if err != nil {
		log.Println(err)
	}
	log.Println(res)

}

B2B

This api allows you to do M-Pesa Transaction from one company to another.

package main

import (
	"log"
	"github.com/AndroidStudyOpenSource/mpesa-api-go"
)

const (
	appKey    = ""
	appSecret = ""
)

func main() {

	svc, err := mpesa.New(appKey, appSecret, mpesa.SANDBOX)
	if err != nil {
		panic(err)
	}

	res, err := svc.B2BRequest(mpesa.B2B{
		Initiator:              "",
		SecurityCredential:     "",
