Authentication Header

Use the new HRAuthConfig (from v2.x.x) class to pass auth header keys

import hotrecharge

# create config class
config = hotrecharge.HRAuthConfig(
    access_code='acc-email', 
    access_password='acc-pwd',
    reference='random-ref'
)

# pass config object to api constructor
api = hotrecharge.HotRecharge(config)

New in v3.x

You can now return response models rather than dict

• model returned is auto-generated by Munch library
• To enable it, flag the return_model=True, defaults to False

# <..>

try:
    # flag return_model -> True in order to return model, (Munch object)
    api = hotrecharge.HotRecharge(config, return_model=True)    

    # lets get available EVDs (electronic vouchers) as models
    evds = api.getEVDs()

    # you can now do
    print(evds.AgentReference)
    print(evds.ReplyMsg)

    x = 0

    # can loop around available evds in stock
    for evd_pin in evds.InStock:
        print(f'------- EVD Pin [{x}]-------')

        print('EVD Brand Name:    ', evd_pin.BrandName)
        print('EVD Pin Value:     ', evd_pin.PinValue)
        print('EVD Current Stock: ', evd_pin.Stock)
        
        print('-----------------------------')

        x++

# can also catch api exceptions
# HotRechargeException is the base class for all exceptions
# check example folder for more
except hotrecharge.HotRechargeException as ex:
    print(f"[HOTRECHARGE ERROR] There was a problem: {ex}")

Performing requests

• this shows how to do basic get requests for different services

import hotrecharge
import pprint

try:
    # get wallet balance
    wallet_bal_response = api.walletBalance()

    # get data bundles
    data_bundles_resp = api.getDataBundles()

    print("Wallet Balance: ")
    pprint.pprint(wallet_bal_response)

    print("Data Bundles Balance: ")
    pprint.pprint(data_bundles_resp)

except Exception as ex:
    print(f"There was a problem: {ex}")

Recharge

Recharge data bundles

• use bundle product code
• an optional customer sms can be send together upon request
• Place holders used include

%AMOUNT% 	    $XXX.XX
%COMPANYNAME%	As Defined by Customer on the website www.hot.co.zw
%ACCESSNAME%	Defined by Customer on website – Teller or Trusted User or branch name
%BUNDLE%	    Name of the Data Bundle

try:
    # option message to send to user
    customer_sms =  " Amount of %AMOUNT% for data %BUNDLE% recharged! " \
                    " %ACCESSNAME%. The best %COMPANYNAME%!"

    # need to update reference manually, if `use_random_ref` is set to False
    api.updateReference('<new-random-string>')

    response = api.dataBundleRecharge(product_code="<bundle-product-code>", number="077xxxxxxx", mesg=customer_sms)

    pprint(response)

except Exception as ex:
    print(f"There was a problem: {ex}")

Recharge pinless

try:
    customer_sms = "Recharge of %AMOUNT% successful" \
                   "Initial balance $%INITIALBALANCE%" \
                   "Final Balance $%FINALBALANCE%" \
                   "%COMPANYNAME%"

    response = api.rechargePinless(amount=3.5, number="077xxxxxxx", mesg=customer_sms)

    print(response)

except Exception as ex:
    print(f"There was a problem: {ex}")

Zesa Recharge

custom Message place holders to use and their representation on end user for zesa transactions:

• %AMOUNT% - $xxx.xx
• %KWH% - Unit in Kilowatt Hours(Kwh)
• %ACOUNTNAME% - Account holdername of meter number
• %METERNUMBER% - meter number
• %COMPANYNAME% - as defined by Customer on the website www.hot.co.zw

Note on Zesa Recharges

Requirements

• A method for Purchasing ZESA Tokens
• It is a ZESA requirement that any purchase must be verified. As such please ensure that you use the checkZesaCustomer() method

    try:
        customer = api.checkZesaCustomer(meterNumber)

        print(customer)

        # prompt user to confirm their details first before performing a recharge

    except Exception as err:
        print('[ERROR] Error getting zesa customer: ', err)

• and prompt the customer to confirm the details before calling this method (api.rechargeZesa(...)).
• There is a new transaction state specifically for ZESA that is Pending verification indicated by reply code 4. Transactions in this state can result in successful transactions after a period of time once ZESA complete transaction.
• You must call Query ZESA method TBD periodically until a permanent resolution of the transaction occurs. This polling of a pending transaction should not exceed more that 4 request a minute. Resending of transactions that have not yet failed can result in the duplication of transaction and lose of funds.
• Please note ZESA does not allow refunds so the cost of any errors cannot be recovered.

Query transaction

• You can now query a previous transaction by its agentReference for reconciliation.
• It is reccommended to query within the last 30 days of the transaction

try:
    response = api.rechargePinless(amount=3.5, number="077xxxxxxx")

    # save agentReference to query for reconciliation
    prevTransactionAgentReference = response.get("agentReference")

    result = api.queryTransactionReference(prevTransactionAgentReference)

    print(response, result)

except Exception as ex:
    print(f"There was a problem: {ex}")

Note on Exceptions

• HotRechargeException is the base class for all exceptions
• All exceptions are subclasses of HotRechargeException
• All exceptions have a message property that contains the error message
• All exceptions have a response property that contains the response object(which is a Munch). In some cases this will be None, so dont get mad if you see None😁.
• One of the best use cases of the response property is when a PendingZesaTransaction exception gets raised. you can save rechargeID, then you can use it later to query the transaction status.

Support 🤿

• This is not an official hot-recharge python library
• I initiated, develop and maintain this library on my own spare time
• A little support can go a long way, i would appreciate it
