eBay API Errors and Warnings

"API" stands for Application Programming Interface, and is the way that we (and other third-party services) communicate with eBay's platform. 

When trying to list to eBay, and your listing fails to post, you will see an API Error message on your Scheduled Listing page (noted in red) that gives an explanation from eBay as to why your listing was not posted. Error message counts are also noted at the top of most pages (the red number box) where it says "Notifications."  You will need to fix the errors in the listing (if possible) before it can be posted to eBay. You may also receive notices from eBay's API if your eBay account is not in good standing, or if you have reached your selling limit. Please contact eBay for questions regarding these types of error messages.

API Warnings (noted in the orange number box at the top of your Auctiva page) are also messages sent from eBay, but do not prevent your listing from posting to eBay and generally speaking, you shouldn't have to take further action.

Common Errors and Fixes:

Shipping:

Package dimensions are less than the minimum allowable limit for service ..... 
Review the allowed sizes for the select shipping service and update the service or size to allowed values. 

Listing Content: 

The item cannot be listed or modified. The title and/or description may contain improper words, or the listing or seller may be in violation of eBay policy.
This error indicates found a word of phrase not allowed on the site. This could be a restricted word or a brand or trademark eBay doesn't allow. 

This item cannot be accessed because the listing has been deleted or you are not the seller.

This generally occurs when you are trying to relist an item after eBay has removed the item from the site. Post from your saved listing or create similar to create a new listing. 

Value provided is not a valid value for Size. Select a value from the available options.
With this or a similar invalid value message, it normally indicates eBay has a list of values acceptable for field in this category. 

This category requires that you provide a valid condition ID value in the ConditionID field.
Review both the condition selected as well as condition notes for the item. 

A required coin or card grading field is missing (for example: “Coin Condition (2) is a required field”).
eBay requires grading details for coins and trading cards categories, such as the coin condition, the grade or the card condition. Fill in the grading field named in the error, then post again.

A required item specific is missing (for example: "The item specific Grade is missing").

eBay may require item specifics to a category. Fill in the item specifics named in the error (for example Grade or Department) in your listing, then post again.

Listing violates the Duplicate Listing policy.
eBay doesn't allow more than one fixed price listing for the same item from the same seller. Instead of posting a second listing, increase the quantity on your existing listing, or end it before posting the new one.
