InfiPlex Inventory & Order Management System (OMS) connects directly to your BigCommerce store. Once connected, InfiPlex pulls BigCommerce orders alongside every marketplace you sell on, sends tracking back when you ship, and keeps BigCommerce inventory in step with your other channels.
Step 1: Create a BigCommerce API Account
- In BigCommerce, open Settings > API Accounts and create a V2/V3 API token. BigCommerce's OAuth guide covers the screen.
- Set the OAuth scopes: Orders: Modify and Products: Modify.
- Note the store hash shown in the API path while creating the account: it is the text between
stores/and/v3/.

- Save. BigCommerce shows the Client ID and Access Token once; copy both.

Step 2: BigCommerce Settings in InfiPlex
- Log into your InfiPlex OMS site and go to Settings > Integrations > BigCommerce.
- big_commerce_client_id: the Client ID
- big_commerce_auth_token: the Access Token
- big_commerce_store_hash: the store hash
- big_commerce_pull_orders: set to Yes to pull BigCommerce orders into the OMS
- big_commerce_pull_orders_from_date: leave blank to start from the moment you enable order pull, or enter an earlier date
- big_commerce_send_tracking_numbers: set to Yes to send tracking back to BigCommerce when an order ships
- big_commerce_sob_enabled: set to Yes to send inventory levels to BigCommerce for SKUs flagged as Sell On BigCommerce
- Save. InfiPlex starts checking BigCommerce for new orders on the next cycle.
Step 3: Confirm the Connection
Go to Tools > Log and choose BigCommerce: Any Log. A working connection shows "BigCommerce Get Order: Successful".
Channel Mapping and Inventory
Orders pushed into BigCommerce from your marketplaces can carry their source channel; see BigCommerce channel mapping by order source. Inventory updates go only to SKUs flagged as sold on BigCommerce: add them to InfiPlex and set them as Sold On BigCommerce.
