Hello ClaudiaC14,
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.
It looks like we've already followed up with you directly via email, but here is the information provided for visibility on the forum:
I’ve reviewed your request and found that the reason for the 404 response is that there is a typo in the request URL.
In your request, the URL is formatted as follows: “https://api.cc.email/v3/contact_lists/lists_id_xrefs”
Our system is expecting this URL to be formatted as follows: “https://api.cc.email/v3/contact_lists/list_id_xrefs”
There is an additional “s” in the “list_id_xrefs” portion of the URL. Removing this extra character should allow your request to be successful.
Please have a look and let us know if you have any other questions!
Regards,
