Chapa Golang

Unofficial Golang SDK for Chapa ET API

Todo:

• We could add nice validations on demand.

Usage

1. Installation

    go get github.com/vonmutinda/chapa

2. Setup

    package main

    import (
        "os"
        "github.com/vonmutinda/chapa"
    )

    func main(){
        chapaAPI := chapa.New(os.Getenv("CHAPA_API_KEY"))
    }

3. Accept Payments

    request := &chapa.ChapaPaymentRequest{
        Amount:         10,
        Currency:       "ETB",
        FirstName:      "Chapa",
        LastName:       "ET",
        Email:          "chapa@et.io",
        CallbackURL:    "https://posthere.io/e631-44fe-a19e",
        TransactionRef: faker.RandomString(20),
        Customization: map[string]interface{}{
            "title":       "A Unique Title",
            "description": "This a perfect description",
            "logo":        "https://your.logo",
        },
    }

    response, err := chapaAPI.PaymentRequest(request)
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    fmt.Printf("payment response: %+v\n", response)

4. Verify Payment Transactions

    response, err := chapa.Verify("your-txn-ref")
    if err != nil {
         fmt.Println(err)
         os.Exit(1)
    }

    fmt.Printf("verification response: %+v\n", response)

Quirks

Suggestions on how to improve the API:

• Introduction of status codes would be a nice to have in the future. Status codes are better than the message in a way considering there are so many reasons a transaction could fail. e.g

    1001: Success
    4001: DuplicateTransaction
    4002: InvalidCurrency
    4003: InvalidAmount 
    4005: InsufficientBalance  
    5000: InternalServerError
    5001: GatewayError
    5002: RejectedByGateway

Juuust an example!
