Sage Pay lib

Note: This library still refers to netcash. I'll update all references to NetCash in the future

A simple library for interacting with Sage Pay SOAP services

Installation

pip install python-netcash

Usage

The preferred way to interact with the repo is using docker.

Quick commands:

Run the tests

Warning: These are integration tests and will hit the netcash endpoints

docker-compose up

• See: tests.py for example code

You must provide the following environment variables in env.dev (you can copy env.example and put your values in):

NETCASH_MERCHANT_ACCOUNT=... NETCASH_SOFTWARE_VENDOR_KEY=...

You customer will provide:

NETCASH_SERVICE_ID=... NETCASH_SERVICE_KEY=...

Integration requirements

In order to integrate with Netcash, you will be required to implement the following functionality:

Tip: You can get an interactive shell with:

docker-compose run --rm netcash ipython

Setup the client

# get environment variables into constants:
from netcash.client import Netcash
import os

NETCASH_MERCHANT_ACCOUNT = os.environ.get("NETCASH_MERCHANT_ACCOUNT")
NETCASH_SOFTWARE_VENDOR_KEY = os.environ.get("NETCASH_SOFTWARE_VENDOR_KEY")

service_id = ...
service_key = ...

netcash = Netcash(NETCASH_MERCHANT_ACCOUNT, NETCASH_SOFTWARE_VENDOR_KEY)

Validate service key

# returns a boolean True if valid account. Otherwise False
netcash.validate_service_key(service_id, service_key)

Request and retrieve merchant statement

# request a statement:

# this is just for readability:
from datetime import date, timedelta

from_date = date.today() - timedelta(days=7) # get the last week's worth of transactions

polling_id = netcash.request_merchant_statement(
    from_date=from_date, service_key=service_key,
)
res = netcash.retrieve_merchant_statement(
    polling_id, service_key=service_key, as_csv_reader=True
)
for row in res.rows:
    print(row)

>> ['2020-04-14', 'OBL', '0', 'Opening Balance', '0.0000', '+', '0', '', '', '']
>> ['2020-04-14', 'CBL', '0', 'Closing Balance', '0.0000', '+', '0']

Contributing

This library is pretty simple. To add support for a new web method do:

1. Add a payload to sagepay/payloads.py
2. Add a method to wrap request in sagepay/client.py
