Hello WLB,
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.
When a contact is deleted via the UI, it’s put into “deleted” status. You can find all of your account’s deleted contacts with the GET Contacts Collection request and the “status” query parameter set to “deleted”.
GET Contacts Collection:
https://developer.constantcontact.com/api_reference/index.html#tag/Contacts/operation/deleteContact
One method that could potentially simplify this process for your use case would be to utilize the Create or Update a Contact request for your sign-up form, rather than separate requests to create, update or obtain the status of a contact. This request will add new contacts and update any existing contacts being submitted through the form, including deleted contacts. Below I’m including our documentation for this request.
Create or Update a Contact:
https://developer.constantcontact.com/api_reference/index.html#tag/Contacts/operation/createOrUpdateContact
Please have a look and let us know if you have any other questions!
Regards,
