Update supplier inventory from third party shopify store

Supplier Inventory Feed

Usage

  • Your supplier uses shopify.
  • They are willing to expose inventory over Shopify API giving you a private app API key and Password.
  • You are using fulfil and has product suppliers defined.

How this works

Read more on Fulfil support site:

Installing dependencies

pip install ShopifyAPI fulfil-client

The dependencies are also included in a requirements.txt file

pip install -r requirements.txt

Running the script

The first step is to set the required credentials as environment variables.

Setup environment variables

The following environment variables are required

SHOP_NAME

The shopify store name. Usually the first part of the .myshopify.com URL you use to access the store admin.

SHOPIFY_API_KEY

The API Key from a Shopify Private app

SHOPIFY_PASSWORD

Password from the private app

FULFIL_SUBDOMAIN

The subdomain of your fulfil instance.

FULFIL_API_KEY

The API key of your fulfil instance. The user must have permission to read and write product suppliers.

SUPPLIER_CODE

The code of the supplier (who own the shopify store). The code can be found on the top right card on the supplier contact. Usually a number.

You can usually source a script with all the variables

export SHOPIFY_API_KEY=
export SHOP_NAME=
export SHOPIFY_PASSWORD=
export FULFIL_SUBDOMAIN=
export FULFIL_API_KEY=
export SUPPLIER_CODE=

Run the script

python sync_inventory.py

This will read the environment variables, connect to shopify, match with product supplier records in fulfil and update them with the inventory available.

Hosting ideas

Hosting this on Python Anywhere

Sign up for Python Anywhere

You need a paid account because free accounts have restrictions on making api calls.

Navigate to files and edit the .profile (or .bashrc) and include the environment variables from above.

Setting up the environment

Click on "Open bash console here" and follow the steps below:

Create a virtualenv.

mkvirtualenv shopify

Install dependencies

pip install ShopifyAPI fulfil-client

Now run the script python sync_inventory.py

If this runs, you can now setup a scheduled task to do this automatically.

Setting up a schdeuled task

Copy the path to pythin on the virtualenv. To get this just run which python

My result was /home/sharoonthomas/.virtualenvs/shopify/bin/python

  • Navigate to Tasks from the dashboard.
  • Paste the command

Example:

/home/sharoonthomas/.virtualenvs/shopify/bin/python /home/sharoonthomas/sync_inventory.py
