Note: iQmetrix APIs are constantly improving to meet the needs of consumers. As a result, the code in this sample applicaton may be out of date.

Getting Started

This guide provides all the steps neccessary to run the iQmetrix Shopify Integration App.

The intended audience for this guide are developers interested in extending the Shopify Integration App.

In this guide, you will be setting up a development store following the Shopify guide.


Before checking out this project, ensure you have the following installed on your computer:

  • Node.js
  • ngrok - Secure introspected tunnels to localhost. Required as Shopify webhooks do not support use with localhost for development
  • Postman - REST Client that allows you to make custom calls

Knowledge Assumptions

This guide assumes the following:

  • Windows Operating System
  • Familiarity with Node.js
  • Familiarity with Git and Github

Setting Up Environment

These steps must be done in sequential order.

Step 1: Set Up Shopify

  1. Follow the Shopify developer's Getting Started Guide to create a development store. When creating your application ensure that the app URL is http://localhost:3000/ and that the redirection URL is http://localhost:3000/auth_token, since express works for port 3000. More information is available from the CODEZUKI blog post.

  2. Download the Postman collection.

  3. Follow the instructions contained in the description of the calls to get your Shopify authentication credentials:

    • Get your Shopify API credentials.
    • Set up a Shopify PARTNER account, log into the partner portal and create an integration application. Ensure ShopName, Scopes, APIKey and CallbackURL are filled in your ENV file in Postman.
    • Run the first request.
    • Press Generate Code and combine pieces so it looks similar to this: https://{{storeName}}.myshopify.com/admin/oauth/authorize?client_id={{clientId}}&scope=write_orders,read_customers&redirect_uri=http://localhost/
    • Copy + paste that into your browser URL. You may have to "approve" the connection. Then you will be directed to a dead page. Copy the "Code" from the URL and place it in the ENV.
  • Exchange CODE for your ACCESS TOKEN
    • Ensure the following fields are filled in you ENV:
      • APIKey
      • Secret
      • ShopName
      • Code

Step 2: Set Up Webhooks

Shopify uses webhooks to push requests to subscribers when events happen in the Shopify system. Detailed information about using the webhook API calls can be viewed at Shopify's API reference.

  1. Launch ngrok by using a terminal and navigating to the folder containing ngrok.exe and entering the following command: ngrok http 3000. This will create a tunnel that will redirect traffic from the ngork forwarding URL to loaclhost on port 3000. You can view traffic at the URL by going to http://localhost:4040/

  2. Use this Postman collection or the (webhook tool) to then subscribe to topics in Shopify using the URL provided by ngrok. The endpoint to use for the webhooks will the the ngrok supplied URL followed by /webhook (ex. http://5541fdac.ngrok.io/webhook). Topics supported are:

  • customer/update
  • customer/delete
  • product/create
  • product/update
  • product/delete

NOTE: The customer/create topic should not be used because creating a customer in Shopify appears to trigger both the customer/create and customer/update topics and the action only needs to be processed once.


Before the App can be run, you must first create a series of Mapping values in [dev-settings.json](path to dev-settings). Configuration is done in JSON format with key value pairs.



"fieldMapping": {
	"{{shopifyProductField}}": {{iqmetrixFieldDefinitionId}}

For each field you wish to sync from Shopify to iQmetrix, there must be a property listed in fieldMapping.

  • shopifyProductField is the name of a property on a Shopify product
    • Endpoint: GET /admin/products/{productId}.json
  • iqmetrixFieldDefinitionId is the Id of a FieldDefinition of the appropriate property to sync


"fieldMapping": {
	"title": 1


Category mapping is required. Enter the Shopify product field that you wish to map as the category to the shopify_settings.productCategory field.

For each Category to be mapped, there must be an entry listed in categoryMapping.

NOTE: Shopify does not directly have a category tree system to organize products so if the category field is a text field the value must exactly match the entry in dev-settings.json in order to be mapped.


"categoryMapping": {
	"{{shopifyCategoryFieldValue}}": {{iqmetrixClassificationId}}

For each category in Shopify, there must be an entry listed here.

  • shopifyCategoryFieldValue is the value of the category field supplied in shopify_settings.productCategory.
  • iqmetrixClassificationId is the Id of a matching Classification (NOT Category)
    • Endpoint: GET https://productlibrary{{UrlSuffix}}.iqmetrix.net/v1/ClassificationTrees({{ClassificationTreeId}})
    • API Reference: Getting a Classification Tree


	"productCategory": "vendor"
"categoryMapping": {
	"Shirt": 399


Manufacturer mapping (unlike category) is optional. If you wish to have mapping to an iQmetrix manufacturer enter the Shopify product field that you wish to map as a manufacturer to the shopify_settings.productManufacturer field.

For each Manufacturer to be mapped, there must be an entry listed in manufacturerMapping.

NOTE: Shopify does not directly have manufacturers on products so if the manufacturer field is a text field the value must exactly match the entry in dev-settings.json in order to be mapped.


"manufacturerMapping": {
	"{{shopifyManufacturerFieldValue}}": {{iqmetrixManufacturerId}}
  • shopifyManufacturerFieldValue is the value of the manufacturer field supplied in shopify_settings.productManufacturer.
  • iqmetrixManufacturerId is the Id of a matching Manufacturer


	"productManufacturer": "vendor"
"manufacturerMapping": {
	"iQmetrix_Test_Store": 10472
