Magento Tax Engine Installation Guide

Follow these steps to establish a seamless data integration between both platforms.

Prerequisites

• Admin access to your Magento account

• A valid Kintsugi account

• Permissions to create integrations and access API credentials in Magento

Step-by-Step: Integrate Magento with Kintsugi

1. Log In to Magento

• Go to your Magento Admin URL

• Enter your username and password

• Click Sign In

• 

2. Get Your Store Name

• Navigate to: Stores > All Stores

• Select your store (e.g., "Main Website Store")

• Copy the store name for later use

3. Start Magento Integration in Kintsugi

• Log in to your Kintsugi account

  

• Go to Data Sources

  

• Click Browse for Integration

  

• Look for Magento and click Connect

  

You’ll see a form requiring six key fields:

• Shop Name

• Magento REST API Domain

• Consumer Key

• Consumer Secret

• Access Token

• Access Token Secret

4. Fill in the First Two Fields

• Shop Name: Paste the name of your Magento store

• Magento REST API Domain: Copy the base URL of your Magento site (e.g., https://818659c132.nxc.li.io) and paste it here

5. Generate Magento API Credentials

• In Magento, go to: System > Extensions > Integrations

• Click Add New Integration

• Fill out the form:

  • Name: Example “Kintsugi Integration”

  • Email: A valid email (e.g., you@domain.com)

  • Password: Your Magento admin password

• Click the API tab

• Under Resource Access, check the following:

  • Sales

  • Catalog

  • Customers

• Click Save

6. Activate the Integration

• After saving, locate your integration in the list (e.g., "test dev")

• Click Activate

• Confirm API permissions again (Sales, Catalog, Customers)

• Click Allow

7. Copy API Credentials

You will now see the following Integration Tokens on screen:

• Consumer Key

• Consumer Secret

• Access Token

• Access Token Secret

Copy and paste each value into the corresponding field in Kintsugi:

1. Consumer Key

2. Consumer Secret

3. Access Token

4. Access Token Secret

8. Complete the Setup

• Once all fields are filled, click Save in Kintsugi

• You should see a success message: "Successfully connected to Magento"

• To confirm:

  • Refresh your Kintsugi page

  • Go to Data Sources and check Manage Integrations

  • Magento should now appear as one of your Active integrations

Next Step: Turn On Tax Calculation

Connecting your store brings your Magento transaction data into Kintsugi, which is what powers your nexus tracking and filings. It does not yet calculate tax at checkout.

To collect tax on Magento orders, install the Kintsugi Sales Tax plugin on your store. That step needs command line access to your Magento server, so loop in whoever manages your Magento environment before you start.

Before you do, check that your Magento and PHP versions are supported. The plugin works on Magento Open Source and Adobe Commerce 2.4.6 through 2.4.9, and Magento 2.4.9 specifically requires plugin version 1.1.0 or later. Versions 2.4.5 and earlier are not support targets.
