eBay settings - Authentication

To improve security, eBay has introduced a new authorization mechanism. After using your eBay user name and password to register with the eBay API once, you will receive a so-called token from eBay which is saved in the system. This token provides authorization for all additional API calls that are performed by the application, such as uploading products, querying the offer status, or downloading sales data. Your login details are not transferred and are therefore much more secure.
Without this token, you cannot exchange any data with eBay. The token has a time limit and must be periodically renewed. Generally, the token is valid for approximately 1.5 years.
Note: You should renew this token before it expires to ensure the continuity of data transfer with eBay. The system does not automatically renew the token.
To receive a token for your eBay login, click the Authentication tab.
This page shows you whether a valid authentication is present or whether you need a new token. To request a new token, click Request Authentication. The first step involves testing the connection to eBay:
Figure 6: The connection is established. A token can be downloaded
If the connection cannot be established, the link is not visible. In this is the case, verify the general settings.
To continue, click Request Authentication from eBay. This will forward you to the eBay sign-in page. Sign in using the user name and the password that you are registered with at eBay. eBay will check the information and provide a token. You must agree to the action. The token is then sent to the ePages system and you are returned to the initial page. Here you can now see that the system is authenticated and the length of time that the token is valid; see Figure 7.

Note: Tokens for the live and for the test environment must be requested separately.
If your sign-in data has changed, or you require a new authentication for another reason, you can delete the current details. To do this, click Delete authentication. The authentication details are then reset and you can request new ones. You can initiate the same action on the General page. The action is contained in the information box.
