What is an API Key and how do I get one?

What is an API key?
The API key is a Universal Unique Identifier (UUID) generated by our system. This will be a 32 bit alphanumeric string. E.g. 15458617-7813-4a37-94ac-a8e6da6f6405

Why do I need an API Key?
You will need an API key to access the eBay Commerce Network API. The purpose of the API key is to give secure access to the API only to the owner of the key.

How do I get my API Key?
When you first apply to the API program, an API key will be generated on approval of your application. You will get an email with your API Key and your Tracking ID on approval. You will also be able to see this information in the Publisher Account Center (PAC)

How do I use the API Key?
You will have to pass the API key and the Tracking ID in your API call. It is required that you pass a valid and active API key and a valid Tracking ID. The API will not return any results if the API key is invalid or expired or if the Tracking ID is invalid or expired. The API key is used for security and the Tracking ID is used for tracking your performance.Example of API call with the API key and Tracking ID

Is an API key specific to a Tracking ID?
No, you can use your API key for all of your Tracking IDs. Unless needed, we suggest that you use one API key for all your Tracking IDs.

Where do I see my API Key information in PAC?
Log into the Publisher Account Center, click on the Product Suite tab. On the top right, you will see the link Manage your API Information. Clicking on this link will take you to the API Information page, where you will see the API Keys and the Tracking IDs.
