Contact deleted in UI; API v3 thinks the email is still in use

[JulieK7237]

A contact was initially added using API v3. It was then manually deleted via the UI. An attempt to add it (again) via the API results in a 409 response: contacts.api.conflict, "Validation failed: Email already exists for contact <contactID>".

Is there a delay or some sort of caching that would prevent UI changes from being immediately visible via the API? If so, what is the expected timeframe and/or is there a workaround available?

Hello @JulieK7237,

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

If the contact has been created previously it still exists in the account even if it has been deleted. You will need to use the PUT method to update the contact and make it active again.

Thank you, Jimmy D. Something tells me you've heard this before, but just in case: if I delete the contact via the Constant Contact UI, it asks me to confirm that I want to completely remove the Contact from my account. So either the UI behaves differently than the API, or the terminology is inconsistent in the worst possible way. Either way it's really, really, misleading == frustrating, time-consuming, and cost-inducing.

Hi @JulieK7237,

The terminology for the UI is more focused on an end-user that is not familiar with our API and programming integrations. I can bring this up to our Product Owners and see what we can do to make everything more consistent.

Was just burned by this too in testing an integration. If it has been deleted it should act deleted -- even if it was a soft delete under the hood.

Is there any way to truly delete the contact at an API level? If not then this isn't a UI vs API thing, it's an inconsistent data thing.

Hello user9863,

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.

Once a contact (email address) has been added into the system, even if it is deleted, the contact entry and details still remain on the back end of the system for reporting and compliance purposes. 

For example, if a contact unsubscribes from your organization’s mailing list, and you were to delete and then re-add that contact, they would be re-added as unsubscribed rather than as a new contact. This allows us to be compliant with the CAN-SPAM Act, as well as other applicable laws and regulations.

Essentially, deleting a contact never really deletes them. It just strips their list memberships, moves them into a “deleted” status, and hides them from being visible in the account.
