Chapa-Go

Unofficial Golang SDK for Chapa ET API

Todo:

• We could add nice validations on demand.
• Add implementation for the remaining API endpoints.

Usage

1. Installation

    go get github.com/Yinebeb-01/chapa-go

API_KEY

Add your API_KEY: CHASECK_xxxxxxxxxxxxxxxx inside config.yaml file. If you want to run the githb action on your forked repository, you have to create a secrete key named API_KEY.

2. Setup

    package main

    import (
        chapa "github.com/Yinebeb-01/chapa-go"
    )

    func main(){
        chapaAPI := chapa.New()
    }

3. Accept Payments

    request := &chapaAPI.PaymentRequest{
        Amount:         10,
        Currency:       "ETB",
        FirstName:      "Chapa",
        LastName:       "ET",
        Email:          "chapa@et.io",
        CallbackURL:    "https://posthere.io/e631-44fe-a19e",
        TransactionRef: 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 := chapaAPI.Verify("your-txn-ref")
    if err != nil {
         fmt.Println(err)
         os.Exit(1)
    }

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

5. Transfer to bank

    request := &BankTransfer{
	    AccountName:     "Yinebeb Tariku", 
	    AccountNumber:   "34264263", 
	    Amount:          10,
	    BeneficiaryName: "Yinebeb Tariku",
	    Currency:        "ETB",
	    Reference:       "3264063st01",
	    BankCode:        "32735b19-bb36-4cd7-b226-fb7451cd98f0",
	}
		
	response, err := chapaAPI.TransferToBank(request)
	fmt.Printf("transfer 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

Just an example!
