General

↑ Back to top

• Display available locations on the Single Product Page: Check this to show customers the available locations for a product on the single product page. Leave unchecked to hide location information from customers entirely.
• Show Locations In: Choose Drop Down or Radio Buttons to control how customers select a location.
• Show “Use Nearest Location” button on the product page: Check this to display a button that lets customers auto-select the closest inventory location using their browser’s geolocation.
• Limit customers to a predefined location: Check this to restrict which location a customer can select or be assigned to.
• Show a heading above the location selector: Check this to display a heading above the selector on the front end.
• Show a title/label for the location selector: Check this to display a title or label next to or above the selector.
• Apply a visible border around the location selection field: Check this to add a border around the dropdown or radio button group.
• Field Background Color: Set the background color of the location selection field.
• Option / Radio Color: Set the text or accent color for dropdown options or radio buttons.
• Option / Radio Font Size: Set the font size for dropdown options or radio labels, accepts units like px, em, or rem.
• Hide out-of-stock locations from customers: Check this to automatically hide any location where the product is out of stock.

• Sync site-wide location with product-page selection: Check this so choosing a location on the product page, or through nearest location detection, also updates the shop-wide location filter. Catalog pages then show the same store. When unchecked, the selection stays with the cart item and only the shop filter widget sets the site-wide location.
• Enable the storefront location popup modal: Check this to turn on the popup location picker. A floating trigger button appears automatically, and Appearance > Menus includes a Multi Inventory box with a Select Store item that opens the same popup.
• Floating Button Placement: Choose the corner of the screen where the floating trigger button appears, for example Bottom right.
• Allow the [ext_mim_store_selector] shortcode: Check this to place the shortcode in any page, post, or widget and show a button that opens the store picker. Use the optional label attribute to change the button text, for example label=”Select Store”. The shortcode shows nothing when this option is off.
• Trigger Button Background: Set the background color of the floating, shortcode, and menu trigger buttons. It is also used as the popup accent color for the selection highlight and primary actions.
• Trigger Button Text Color: Set the text color of the floating and shortcode trigger buttons. It is also used for the contrast text inside the popup.
• Automatically suggest nearest location on first visit: Check this to request the visitor’s browser location on their first visit, when no store is chosen yet, and suggest the nearest store. Customers can accept it or open the store picker. Nothing happens if permission is denied, and an existing choice is never overridden.

REST API

↑ Back to top

• Create a WooCommerce REST API key: Go to WooCommerce > Settings > Advanced > REST API and click Add key. Choose a user who can manage WooCommerce, set permissions to Read/Write, then copy the Consumer Key and Consumer Secret.
• Authenticate (same as wc/v3): Over HTTPS, send the Consumer Key as the Basic Auth username and the Consumer Secret as the password, or pass consumer_key and consumer_secret as query parameters. These are the same keys you already use for products and orders.
• Base URL: Use https://yourdomain.com/wp-json/ext-mim/v1 and replace yourdomain.com with your site address.
• Default Stock vs location rows: This matches the product screen, where Default Stock > Quantity is separate from each Location row’s Stock Quantity. WooCommerce product stock (_stock) is the total across all of them, so never confuse it with a single location’s quantity.
  • location_id = 0: Default Stock (is_default=true). Preferred for reads and writes.
  • PATCH …/inventory/{product_id}/default: Alias for updating Default Stock only.
  • location_id = {location post ID}: Updates that location’s Stock Quantity row only and does not overwrite Default Stock.
• Endpoints: Use the following routes under the base URL.
  • GET /inventory: Returns Default Stock and every location row. Filter by product_id, location_id (0 = default), sku, page, and per_page.
  • PATCH /inventory/{product_id}/0: Update Default Stock.
  • PATCH /inventory/{product_id}/default: Same as location_id=0.
  • PATCH /inventory/{product_id}/{location_id}: Update one location inventory row.
  • GET /locations: Returns id, name, and parent_id.
• Readable fields (GET): product_id, location_id, location_name, is_default, assigned_location_id, stock_quantity, price, sale_price, low_stock_threshold, status, stock_status, sku, inventory_sku, inventory_name, manage_stock, backorders, priority, date, expiry_date, has_price.
• Writable fields (PATCH, partial): stock_quantity, price, sale_price, low_stock_threshold, inventory_sku, priority, date, expiry_date, has_price, manage_stock, stock_status, backorders. Send only the fields you want to change. stock_quantity is an absolute value, not a delta. inventory_sku and has_price apply to location rows only. manage_stock, stock_status, and backorders are product-level, the same as Manage Stock.
