1. Log in to your ads account by going to ads.twitter.com
2. Once at the campaign dashboard, look to the upper right for your account name
3. Click on the account name and choose the "Edit access to account"option
4. This will take you to a new page where you will need to hit the "Add access" button
5. You will then be prompted to input a Twitter handle. This should be the @SC_<client name> account. Be sure to enable at least "Ad Manager" for the permission level since anything less will not allow SocialCode to run ads for you.
