ChannelAdvisor's multi-channel eCommerce solutions provide sellers with a seamless way to manage inventory, aggregate and publish product data to multiple marketplaces. In the Parts & Accessories space, fitment is a critical piece to enjoying marketplace and website success.

myFitment integrates directly with ChannelAdvisor's API to deliver fitment for those sellers with a presence on eBay MOTORS.

How It Works


On the Settings page for the myFitment subscription you wish to tie to your ChannelAdvisor account you are presented with text fields that correspond to your ChannelAdvisor account, profile, and fitment landing field information:

Figure 1

Each field label contains a tooltip explaining the format of its respective identifier.

To find the Profile ID, first login to your ChannelAdvisor account. Then click on the link illustrated below:

Figure 2

This will open a page that will show you your Profile ID. See below:

Figure 3


Copy and paste that profile ID back to the myFitment page in Figure 1. 

Then click the "Update Subscription" button and return to your ChannelAdvisor page.

After clicking the Update Subscription button, a request for access will appear within your ChannelAdvisor account. You must approve this request for myFitment to access your ChannelAdvisor account in order for myFitment to publish your fitment data to ChannelAdvisor.

 You will see something similar to Figure 4 below.

Copy and paste the Account ID above. Click "Approve Access". Return to the myFitment page in Figure 1 and paste the Account ID.

Fitment Attribute

To fill out the last field, you will need to either know what fitment attribute you are going to use for your eBay data, or you will need to create one. To view your attributes, follow the instructions in Figure 5 below. If you need assistance, contact a ChannelAdvisor support representative.

Cut and paste the attribute name back into the myFitment page in Figure 1. Click "Update Subscription" again. This is the final step.


Once you complete the Authorization process, myFitment will automatically publish your eBay fitment to your ChannelAdvisor account, rather than to eBay directly. This is important, because if you are a ChannelAdvisor customer who uses myFitment to publish fitment directly to eBay, your ChannelAdvisor account will remove your fitment each time an item revision is made within ChannelAdvisor.

Ongoing Maintenance

ChannelAdvisor stores this fitment information in a static text field. eBay updates their Master Vehicle List each quarter. As such, your fitment information will occasionally become out of date. You will know when a listing's fitment is out of date in your ChannelAdvisor account when you receive errors during the item update process.

eBay automatically updates your fitment information on-site, so your fitment on eBay remains valid. It's important when this occurs to re-import that listing from eBay into your myFitment account, and republish it to ChannelAdvisor. This is easily accomplished using the "down arrow" and "up arrow" icons next to the affected listing in the myFitment listing management screen, accessible by the Listings menu item:

myFitment support staff can aid you in performing this operation for all of your listings at once. Open a support request if you find that many of your listings were affected by an eBay Master Vehicle List update.
