Paynow Zimbabwe Python SDKPython SDK for Paynow Zimbabwe's APIPrerequisitesThis library has a set of prerequisites that must be met for it to workrequestsInstallationInstall the library using pip$pipinstallpaynowand import the Paynow class into your projectfrompaynowimportPaynow# Do stuffUsage exampleCreate an instance of the Paynow class optionally setting the result and return url(s)paynow=Paynow('INTEGRATION_ID','INTEGRATION_KEY','http://google.com','http://google.com')Create a new payment passing in the reference for that payment (e.g invoice id, or anything that you can use to identify the transaction and the user's email addresspayment=paynow.create_payment('Order #100','test@example.com')You can then start adding items to the payment# Passing in the name of the item and the price of the itempayment.add('Bananas',2.50)payment.add('Apples',3.40)When you're finally ready to send your payment to Paynow, you can use thesendmethod in thepaynowobject.# Save the response from paynow in a variableresponse=paynow.send(payment)The response from Paynow will b have some useful information like whether the request was successful or not. If it was, for example, it contains the url to redirect the user so they can make the payment. You can view the full list of data contained in the response in our wikiIf request was successful, you should consider saving the poll url sent from Paynow in the databaseifresponse.success:# Get the link to redirect the user to, then use it as you see fitlink=response.redirect_url# Get the poll url (used to check the status of a transaction). You might want to save this in your DBpollUrl=response.poll_urlMobile TransactionsIf you want to send an express (mobile) checkout request instead, the only thing that differs is the last step. You make a call to thesend_mobilein thepaynowobject
instead of thesendmethod.Thesend_mobilemethod unlike thesendmethod takes in two additional arguments i.e The phone number to send the payment request to and the mobile money method to use for the request.Note that currently only ecocash is supported# Save the response from paynow in a variableresponse=paynow.send_mobile(payment,'0777777777','ecocash')The response object is almost identical to the one you get if you send a normal request. With a few differences, firstly, you don't get a url to redirect to. Instead you instructions (which ideally should be shown to the user instructing them how to make payment on their mobile phone)if(response.success):# Get the poll url (used to check the status of a transaction). You might want to save this in your DBpoll_url=response.poll_urlinstructions=response.instructionsChecking transaction statusThe SDK exposes a handy method that you can use to check the status of a transaction. Once you have instantiated the Paynow class.# Check the status of the transaction with the specified poll url# Now you see why you need to save that url ;-)status=paynow.check_transaction_status(poll_url)ifstatus.paid:# Yay! Transaction was paid for. Update transaction?else:# Handle thatFull Usage ExamplefrompaynowimportPaynowpaynow=Paynow('INTEGRATION_ID','INTEGRATION_KEY','http://google.com','http://google.com')payment=paynow.create_payment('Order','test@example.com')payment.add('Payment for stuff',1)response=paynow.send_mobile(payment,'0777832735','ecocash')if(response.success):poll_url=response.poll_urlprint("Poll Url: ",poll_url)status=paynow.check_transaction_status(poll_url)time.sleep(30)print("Payment Status: ",status.status)
