Old versions support

Hi guys,


As you plan to migrate to V3, can you confirm that the existing API  version will remain available and working ?



Re: Old versions support



Thank you for reaching out to Constant Contact API Support.


The plan will be to eventually retire our V1 and V2 API versions as we move users over to V3. While I don't have a specific timeframe I can provide quite yet, we will be sure to announce an end-of-life plan for any legacy APIs so that everyone has enough time to plan and develop new integrations using the V3 API.


Please let me know if you have any other questions!
