In order to connect your CJ affiliate account to Afflytics, you will need a CJ Personal Access Token and your CJ CID (company id).
You can obtain a Personal Access Token by visiting https://developers.cj.com/account/personal-access-tokens, logging into your CJ account, and Registering a New Personal Access Token. It's best to create a new Personal Access Token specifically for Afflytics. For "Token Name", you can call it something like "Afflytics". See the screenshot below.
Once you have registered a new Personal Access Token, make sure you copy it and keep it somewhere safe.
You can obtain your CID by logging into your CJ account. You will see your CID at the top right of the page (on the navigation bar) under your user's name. See screenshot:
Once you have a Personal Access Token and your CID, you can connect your CJ account to Afflytics by clicking "Connect" under the CJ logo on the Afflytics Setup page.
