Hello,
Thank you for reaching out to Constant Contact API Support.
We are currently hard at work on a new API which will have A/B Test features, however they will be added after it's released. We're not yet ready to give a date on when that might be. Currently there are no plans to bring A/B Test into our current V2 API.
Please let me know if you have any other questions!
Sincerely,
David B.
Tier II API Support Engineer
