Ensure that the add-on "ATD" is installed and enabled at your X-Cart store. (See add-on management instructions for X-Cart 5.5).

Note that X-Cart's ATD integration requires a few other add-ons for operation:

"Make/Model/Year"

"Shop By Brand"

"Auto catalog import" (provides building blocks for catalog provider integrations)

"Split Shipment" (enables splitting an order into multiple packages shipped from different locations)

The above-named add-ons must be installed and enabled for as long as you use the ATD integration.

Ensure that the "Time zone" setting for your X-Cart store has been adjusted properly; it can be found on the Localization > Units & Formats page of your X-Cart store's Admin area.

Important: The time zone specified in php.ini in your store's server environment must be the same as the time zone specified in your X-Cart store's Localization settings.

Check with the X-Cart team to ensure the necessary server environment setup required for your X-Cart store to use ATD has been completed.

Obtain your API credentials and save them in your ATD integration settings. For details, see:

The import of prices from ATD is possible only in US Dollar. Consider whether you will need to perform currency conversion for prices imported from ATD and complete the necessary setup for currency and price conversion accordingly. See the guide on Setting up the Currency & Price Conversion for more details.

Note that your store's default currency is specified in your store's Localization settings (Store > Localization, Currencies tab). For more information on X-Cart store configuration related to currencies, see Currency.

Ensure that your X-Cart store features an ATD compatible catalog, comprising brands, categories, products, and product fitment data. You can import the data for this catalog directly from ATD or acquire data from alternative sources, such as manual entry or importing from catalog providers like AutoSync, ASAP Network, or SEMA Data using X-Cart's auto data provider integrations. Specific instructions for ATD can be found in the Catalog Import and Management (ATD Integration) section.

The tax setup when using ATD integration does not have any specifics. You simply configure taxes as usual.

If you plan to have stock available for delivery from your store's own warehouse, complete the store configuration related to shipping. Ensure that you specify the address of your store's warehouse, from which products will be shipped to buyers, as your store's Ship-From address. Also, configure the shipping methods and rates that will be available for shipping products from your store's Ship-From address to buyers.

If you do not plan to keep stock in your store's warehouse [which may be the case if you want ATD to handle all orders], you do not need to configure shipping in your store.

In any case, remember to set the shipping method to be used by default for ATD orders; ATD will need this information to provide buyers with an estimation of the shipping cost for their orders. See Configuring the Shipping Settings.
