Python Daraja
Description
Python Wrapper for handling payment requests through the Daraja MPESA API
Contribution
- Refer to the CONTRIBUTING GUIDE.
Usage
Installation
pip install python-daraja
Initial Setup
- Set the following constants first before proceeding
from python_daraja import payment
payment.SHORT_CODE = "YOUR_SHORTCODE"
payment.PASSKEY = "YOUR PASSKEY"
payment.CONSUMER_SECRET = "YOUR CONSUMER SECRET"
payment.CONSUMER_KEY = "YOUR CONSUMER KEY"
payment.ACCOUNT_TYPE = "PAYBILL" # Set to TILL to use BuyGoods instead of Pay Bill
- The first function to call is one which would trigger an automatic STK Push on your customer's phone. There is no simpler way of knowing whether the customer has successfully paid or not (failures such as inputting the wrong PIN or just cancelling the request altogether). You are therefore advised to set up a simple server with an endpoint that will accept
POSTrequests from Daraja API with the details of the transaction. - For the server, it must be secure (
httpsinstead ofhttp), it must not belocalhostnor127.0.0.1:$PORT. - You can use services like
ngrokto tunnellocalhostto live secure server. - Your server's endpoint should also accept a
POSTrequest hence you may need to disable constraints such asCSRF(outside the scope of this project). - If at all you must have CSRF Protection in your server, then you need to allow requests originating from the following IP addresses (whitelisting):
- 192.201.214.200
- 196.201.214.206
- 196.201.213.114
- 196.201.214.207
- 196.201.214.208
- 196.201.213.44
- 196.201.212.127
- 196.201.212.128
- 196.201.212.129
- 196.201.212.136
- 196.201.212.74
- 196.201.212.69
- You can now proceed by triggering the payment process; you should expect a Python Dict object with the results of the process. This will only tell you whether it was successful and not whether the customer has actually paid.
from python_daraja import payment
details = payment.trigger_stk_push(phone_number=2547123456, amount=1, callback_url='https://your-domain/callback/',
description='Payment for services rendered',
account_ref='Python Good PHP Bad and Co.')
print(details)
-
The MPESA Gateway will then send some
POSTdata to your endpoint if the customer pays, otherwise, you will not receive any data showing that your customer hasn't paid a dime. -
It is advisable to save the details received from the previous method call to a DB of your choice. Some of those details are used for other subsequent method calls especially in getting the transaction status of your payment requests.
-
In order to query the details of a payment request made through the automatic STK Push above:-
from python_daraja import payment
details = payment.query_stk_push(checkout_request_id='ws_CO_DMZ_123212312_2342347678234')
print(details)
- Getting a
0as the Response Code or Result Code generally means that the transaction was successful, any other digit signifies otherwise.
Remarks
- Unfortunately as of the moment of release of this package, Safaricom has internal problems with other types of transactions such as
C2B. Maintainers of the project will work on implementing more features when the issues are addressed.
