How to Use Mecaparts: A Complete Setup Guide for Auto Parts Sellers

Organize your auto parts store on Shopify and simplify TecDoc usage — with your own TecDoc API access.

Mecaparts is designed to help auto parts sellers manage their catalogs, suppliers, and product compatibility directly inside Shopify. But to use Mecaparts effectively, you must already have TecDoc API access. This connection is what powers product searches, detailed vehicle compatibility data, and accurate part imports — without the need for complex tools or manual entry.

This guide walks you through setting up Mecaparts step-by-step, based on the official documentation.

1. Install Mecaparts on Your Shopify Store

• Go to the Shopify App Store and install Mecaparts.
• Accept the permissions so the app can manage products, collections, and store data.

2. The Importance of TecDoc API Access

• Mecaparts’ Plan requires you to already have an active TecDoc API key and provider ID.
• Without this, Mecaparts cannot pull in product data, vehicle compatibility information, or OEM/IAM references.
• This API link ensures you can:
  • Search for the right parts quickly
  • Get accurate product descriptions and fitment data
  • Import items directly into Shopify without manual uploads

3. Connect Your TecDoc API to Mecaparts

• Enter your TecDoc API key and provider ID in the Mecaparts setup page.
• Once connected, you can instantly search and import parts from TecDoc inside Shopify.

4. Set Your Language and Country

• Choose your preferred language and target country for product data.
• This ensures all product descriptions, formats, and units match your market.

5. Activate Manufacturers

• Mecaparts enables around 35 major manufacturers by default.
• Activate or deactivate them according to your store’s inventory.
• Activated manufacturers automatically include models and engines for accurate vehicle filtering.

6. Manage Suppliers

• Access the built-in supplier list that comes with Mecaparts.
• Search and filter suppliers for internal management.
• If you need a supplier not listed, request it from Mecaparts support.
• Note: Supplier details are only for internal use — they won’t be shown to customers.

7. Configure Vehicle Filters

• Install Shopify’s free Search & Discovery app.
• Add the CAR variant metafield to your filters for quick vehicle-based navigation.
• Place it at the top so customers can easily find compatible parts.

8. Search & Import Products from TecDoc

• With your TecDoc connection active, you can search by:
  • Vehicle selector (make → model → engine)
  • VIN or KBA number
  • OEM or IAM reference numbers
• Add products to Shopify with the + button, setting price and quantity on the spot.

9. Organize and Publish Your Store

• Use Mecaparts’ Categories Management to organize your catalog.
• Publish products to your store and keep them synced automatically.
• Test search and filter features before going live.

Final Thoughts

Mecaparts streamlines running an auto parts store in Shopify using your own TecDoc API access. By connecting TecDoc to Mecaparts, you centralize part searches, product imports, and compatibility data in one place, saving you hours of manual work.
