Overview of uploading an inventory of listings as a dealer or as a third party

eBay Motors Pro has a simple and robust protocol for uploading your stock. Using a few straightforward tools, you could manage all your listings in an office tool like Excel, or with the assistance of a programmer or developer automatically send entire inventories on behalf of as many sites and dealers as you like.

The overview below will answer the majority of questions you might have while creating an upload file for eBay Motors Pro. We don't provide dedicated technical support for the Upload service, but if you have a question which is not covered here, please Contact Us and we'll update the information where possible.

Account requirements

Every dealer uploading their inventory, either through our webform or through the http upload URL, will need to have registered with eBay and activated their eBay Motors Pro account. Both trial-period and paying dealers can upload listings. A single account corresponds to a single dealer site - this means that a multiple-site franchise needs several accounts.

For someone else to upload their inventory on their behalf, a dealer must create a special Upload username and password, which protects a dealer's account by allowing them to authorise a third party to list on their behalf without actually sharing their eBay User ID and password. Upload usernames and passwords are created through the My Settings part of the eBay Motors Pro website.

Upload process & required files

The basic process is the same regardless of whether you're uploading through eBay Motors Pro (Create Listings> Bulk Upload/ Download), or sending files to the HTTP upload URL, and also whether you're sending listings for the first time or updating details of existing listings. Please refer to the box to the right entitled '3 steps to upload an entire inventory'.

You (and the dealer if you're uploading on someone's behalf) will receive status emails after each upload, detailing any errors which may occurred due to file formats, syntax or content.

See the Technical Specification for more information.

3 steps to upload an entire inventory

  1. Create an XML file containing the entire inventory using the specs on this page, and validate it against the XSD (see Resources and Tips for more information)
  2. Place the XML file and digital photos into a ZIP file (See the Technical Specification for more information)
  3. Either upload the file via the webform found in eBay Motors Pro (Create Listings > Upload inventory) OR send the file via HTTP (POST) to

Resources & tips for developing in XML for eBay Motors Pro

If you're familiar with uploading your listings from Excel or other tools in CSV format, then these resources and tips could be helpful in helping you transition to using XML. Please note that the use of tools and websites not provided by eBay is at your own risk.

XML validators

You can save yourself development time by ensuring that your XML validates against the published XSD, available here. There are several online tools available free-of-charge of which we recommend eBay is not responsible for the content of external sites.

To avoid test listings appearing on eBay while still developing,

make sure you set the "Unpublished" flags in the XML for each listing you upload. This way the listings will appear in your Inventory on eBay Motors Pro, but not on the eBay website. When you are ready to 'go live', simply clear that flag.

Listings on eBay are all subject to eBay's policies and User Agreement,

which all eBay Motors Pro Dealers will have agreed to. Make sure you're aware of what this means for you/ your clients.

If a user's inventory is inactive for 30 days or more,

their account will be deactivated until their inventory is updated.

If you're going to be uploading a lot of listings,

make sure you read the section in the documentation about file sizes. If you exceed the maximum upload file size, your upload will be rejected. There are several scaleable ways to reduce the size of your ZIP files, detailed in the documentation.

If a dealer changes their upload username and password,

and you're uploading via the HTTP URL on their behalf, your upload will fail. In this case, it is up to you to contact the dealer and ascertain why they have changed their details.
