Email Sending Issue

I want to send emails through API using contact list and email template created in constant contact .
According to given methods, I can see option to send email with parameter Campaign ID but not list ID. Is it possible to send list id along with campaign id.


Re: Email Sending Issue

Hello @YosvaniA,


Thank you for reaching out to Constant Contact's API Support.


When using our v2 API you would use the below JSON to add the listID.


"sent_to_contact_lists": [
            "id": "1"

You can find reference to this when creating an email campaign or when updating an email campaign. Just search the page for sent_to_contact_lists to find the needed information.
