Hello B2ED,
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.
If you are developing your own application for integration using our V3 API to gather all contacts unsubscribed via Constant Contact, the easiest way to pull this data is by calling the Contacts endpoint.
To only capture active contacts that have unsubscribed, you can call:
GET
https://api.cc.email/v3/contacts?limit=500&status=unsubscribed
However, to also capture contacts previously unsubscribed that have been deleted, you'd want to add the deleted value to the status parameter and then parse your results for contacts with "permission_to_send": "unsubscribed" from the results, as it will return all unsubscribed and all deleted contacts:
GET
https://api.cc.email/v3/contacts?limit=500&status=unsubscribed,deleted
If more than 500 results are returned, at the bottom of the response body will be the link to call the next page, which will look like this:
"_links": {
"next": {
"href": "/v3/contacts?cursor={value}
You will then take that link to make another call to view the next page of results:
GET
https://api.cc.email/v3/contacts?cursor={value}
Below is the related documentation for this endpoint:
