There are two main benefits to hosting images with Walmart:

• You have your own dedicated image hosting space on our server and tools for efficient processing.
• You can quickly upload image files and associate them with your items.

Obtaining SFTP Credentials

You can use Secure File Transfer Protocol (SFTP) to transfer files over a network connection.

Obtaining storage space and credentials

Before you begin transferring files, you must complete the onboarding process. The onboarding process includes:

• Complete Registration
• Complete Your Partner Profile Before Going Live

Requirements

To complete all of the necessary requirements, you will need:

• Image files that fulfill the resolution and size requirements listed in 
• Installed SFTP software, such as FileZilla or Win SCP.
• Login credentials from your Integration Engineer.

Process flow

We recommend the following process flow:

1. Naming image files in accordance with Walmart’s naming convention (see below).
2. Uploading images using SFTP software.
3. Setting up items with images.

Naming conventions

Each image you submit must have a unique file name. Do not upload two or more files with the same name (i.e. shirt.jpg). To ensure unique file names, we recommend naming your files using the UPC as in the images below.

Uploading files via SFTP

There are two ways to connect to the Walmart system and upload files:

1. Through a graphical user interface.
2. Through a command line interface.

For both, you will need the Partner ID and Password you created during the onboarding process.

Overall instructions

1. If you have more than 10,000 files to transfer, create the top-level directory.
   • Any directory you create should follow the Walmart naming convention WM_Images_01...0n.
   • If you are using the command line to create directories, use the mkdir <dirname> command.
   • If you are using FileZilla or WinSCP, follow their directions on how to create directories and transfer files.
2. Only create a one-level directory with image files inside; do not create multi-level subdirectories.

Transferring images using a graphical user interface

You can use FileZilla for Mac and Win SCP for Windows.

Using FileZilla (for Mac)

Using Site Manager, configure the Transfer Settings tab:

1. Select Active and Limit number of simultaneous connections
2. Maximum number of connections, input 1
3. Click Connect

Select the General tab. Then:

1. Enter seller-ft.walmart.com in the  Host text box
2. Select SFTP-SSH File Transfer Protocol for Protoco
3. Select Normal for Logon Type
4. Enter your Partner ID for User and Password
5. Click Connect
   
   

Using Win Scp (Windows)

Open the Login page:

1. Select File protocol: SFTP
2. Enter Host name: seller-ft.walmart.com
3. Enter User name and Password
4. Click Login
   
   

Transferring images using a command line interface

1. Connect a SFTP user to the seller-ft.walmart.com

2. Navigate to your directory. For example:

3. Transfer files using the 'put' command. The system shows the status of your uploaded images.

When you are finished transferring image files, use the ' quit' command to close your connection to the Walmart system.

Setting up items with images

Via Seller Center  

1. The Full Item Spec includes the Main Image fields where you can add the image references.

1. Use the Partner ID you obtained after the onboarding process:
   1. partnerId/imagefilepathname
   2. If you uploaded images under a directory, follow this directory structure: partnerId/dirname/imagefilepathname
2. For example, let’s say you are selling an iPhone case with a UPC barcode as 123456789.jpg. Your Partner ID is “topwmseller” and you uploaded two images: the Main Image is named 000123456789.jpg and the Additional Image is 000123456789_AV.jpg in the main root folder. Your updated Spec may look like this:

Via API

You can use an API POST to create or update items in bulk.

For the Main Image, in the XML payload, add the following attributes:

<mainImage>
          <mainImageUrl>partnerId/imagefilepathname
          </mainImageUrl>
</mainImage>

For the additional images, in the XML payload, add the following attributes:

<additionalAssets> <additionalAsset> <assetUrl>partnerId/ additionalimagefilepathname1</assetUrl> <assetType>

SECONDARY</assetType> </additionalAsset> <additionalAsset> <assetUrl> partnerId/ additionalimagefilepathname2</assetUrl> <assetType>

SECONDARY</assetType> </additionalAsset> </additionalAssets>
