        callbackUrl //"/lipwa/reconcile",
        timeoutUrl //"/lipwa/timeout",
        resultUrl //"/lipwa/results",
    }
)

Send an STK push request

mpesa.stkPush(
    254705459494,
    10,
    "ACCOUNT", // You can ignore this, the code will generate a unique string
    "Transaction Description", // Optional
    "Remark" // optional
).then(({ error, data }) => {
    if (data) {
        const {
            MerchantRequestID,
            CheckoutRequestID,
            ResponseCode,
            ResponseDescription,
            CustomerMessage
        } = data
        console.log(MerchantRequestID)
    }

    if (error) {
        const { errorCode, errorMessage } = error
        console.log(errorCode, errorMessage);
    }
})

// Or use the API directly

stkPush(
    254705459494,
    10,
    "ACCOUNT", // You can ignore this, the code will generate a unique string
    "Transaction Description", // Optional
    "Remark" // optional
).then(({
    error,
    data
}) => {
    if (data) {
        const {
            MerchantRequestID,
            CheckoutRequestID,
            ResponseCode,
            ResponseDescription,
            CustomerMessage
        } = data
        console.log(MerchantRequestID)
    }

    if (error) {
        const { errorCode, errorMessage } = error
        console.log(errorCode, errorMessage);
    }
})

Or, if inside an async function

async () => {
    const { error: { errorCode, errorMessage }, data: {
        MerchantRequestID,
        CheckoutRequestID,
        ResponseCode,
        ResponseDescription,
        CustomerMessage
    }
    } = await mpesa.stkPush(
        254705459494,
        10,
        "ACCOUNT",
        "Transaction Description",
        "Remark"
    )

    console.log(MerchantRequestID)

    // TIP: Save MerchantRequestID and update when you receive the IPN
}

C2B register callback URLs

mpesa.registerUrls("Completed" | "Cancelled").then(({
    error,
    data
}) => {
    if (data) {
        const {
            ResponseCode,
            ResponseDescription
        } = data
        console.log(ResponseDescription)
    }

    if (error) {
        const { errorCode, errorMessage } = error
        console.log(errorCode, errorMessage);
    }
})

mpesa.sendB2C(
    phone, 
    amount, 
    "BusinessPayment" | "SalaryPayment" | "PromotionPayment", 
    "Some remark", 
    "Some occasion"
).then(({
    error,
    data
}) => {
    if (data) {
        const {
            ConversationID,
            OriginatorConversationID,
            ResponseCode,
            ResponseDescription
        } = data
        console.log(OriginatorConversationID)

        // TIP: Save `OriginatorConversationID` in the database, and use it as a key once you receive the IPN
    }

    if (error) {
        const { errorCode, errorMessage } = error
        console.log(errorCode, errorMessage);
    }
})

Send B2B

mpesa.sendB2B(
    phone, 
    amount, 
    "BusinessPayBill" | "BusinessBuyGoods" | "DisburseFundsToBusiness" | "BusinessToBusinessTransfer" | "MerchantToMerchantTransfer", 
    "Some remark", 
    "Some occasion"
).then(({

    if (data) {
        const {
            ConversationID,
            OriginatorConversationID,
            ResponseCode,
            ResponseDescription
        } = data
        console.log(OriginatorConversationID)

        // TIP: Save `OriginatorConversationID` in the database, and use it as a key for update
    }

    if (error) {
        const { errorCode, errorMessage } = error
        console.log(errorCode, errorMessage);
    }
})
