Hello AvromFinkelsteinF,
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.
I was able to verify that the timestamps that you provided match what is in our logs, but I haven’t yet been able to replicate the issue that you are running into. So far in testing when adding single or multiple contacts using the bulk endpoint /v3/activities/contacts_json_import I am showing the corresponding contacts as being added at or after the "started_at" timestamp, so thank you for bringing this to our attention.
Because your log results are inconsistent with the documentation and my testing, I’ll be opening up a case to look into this further. Our team will follow-up with you via the email address on file for your account with our findings.
For follow-up or questions specific to this issue, please feel free to contact our team directly via email at webservices@constantcontact.com, and reference case number 29220720.
