Begin using Commission Junction's Web Services today by registering for your own developer key. Your developer key will give you access to all applicable APIs, according to whether you are participating as an advertiser or a publisher.
Please remember to protect your developer key in the same fashion as your CJ Account Manager client login information.
Please enter the email address and password you use to login to the CJ Account Manager below. If you do not have a CJ Marketplace Advertiser or Publisher account, you must create one prior to requesting a developer key. For more information, go to www.cj.com.
