I was able to schedule my email campaign via API until yesterday. Here is the screenshot of the error.

Any advice would be appreciated.

Hello marvsweather,


Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.


Based on our logs for the request id that you provided, it looks like the error message returned for that 400 response was: “Campaign Email Schedule Date cannot be parsed, please include a valid schedule date with this request”.


We were able to locate the request body which contained {"scheduled_date":"2022-07-2T14:17:00.000Z"}. 


It looks like you may have already resolved this issue, but for this example the date value for “2022-07-2” must be formatted like “2022-07-02” to pass through.


Please have a look and let us know if you have any other questions!
