The first step is to create a Commission Junction account, if you do not already have one.
Once you have an account, login and click on Account >> Websites.
From there you can add your website or grab one of your current Campaign IDs:
Next, we need to get your developer key.
To get your developer key you will need to login to the CJ Developers Portal (using your CJ username and password).
After you login, click on Authentication >> Personal Access Tokens:
Give your Token a name and click Register.
Your Token will then be given.
Please Note: When using your Token, do not include the Token name.
The last step in the process is to make sure you have applied for affiliate programs inside CJ. If you have not been approved for any then nothing will show when you search for products.
To apply for programs go to Advertisers and then search for advertising in your market and click Join Program
