pymart usage

This API wrapper is still unfinished, but is still very useful. I am using it currently. Feel free to contribute.

To begin using the API, you will need your private_key, consumer_id and channel_type. These are all provided by walmart once you have a seller account.

Retrieve Item Information

We can ask for single item information, or for information in bulk.

Single Item

import pymart
w = pymart.Walmart(private_key, consumer_id, channel_type)
r = w.get_item('some_sku_123')
r.content       # The xml data string

I'm using the requests library to make requests, and what is returned is the Request object.

Bulk Item

import pymart
w = pymart.Walmart(private_key, consumer_id, channel_type)
r = w.get_all_items(offset=0, limit=20)
r.content       # The xml data string

You will have to do this many times to get all of your items, if you have many of them.

Bulk Item (with feeds)

We can also get our items and information from a feed, which returns a csv file.

import pymart
w = pymart.Walmart(private_key, consumer_id, channel_type)
r, data = w.get_item_report(cleaned=True)
# data looks something like [[headers], [row], [row], ...]

Here, r is again the Request object, and data is a list of lists. It looks like what would be returned by csv.reader(f).

Orders

Similarly, we can retrieve order information.

Single Order

import pymart
w = pymart.Walmart(private_key, consumer_id, channel_type)
r = w.get_order('123456789') # arg is purchase order id
r.content # xml data string

Bulk Orders

For some reason, the Walmart API does not provide a way to filter orders by modified_date, so you'll have to do with created_start_date and created_end_date...

import pymart
w = pymart.Walmart(private_key, consumer_id, channel_type)
r = w.get_all_orders(created_start_date='<Some ISO 8601 DateTime>', status='Created', limit=200)
r.content # xml data string

If there are more than 200 orders in the response, then a nextCursor element will be provided and you can provide that as the sole argument to the get_all_orders() method to retrieve the next batch of orders. There are more possible arguments to this method, take a look at the source if you need to filter your results further.

Lastly

There are a few more methods I have provided that will return an XML data string through r.content. I would suggest just looking through the source code of pymart.py. It's pretty easy to read and add on to. If you add onto it, just mimic how I "signed" the requests in other methods. That authorization signature was the most annoying part of writing this wrapper. Hope this is useful to someone.
