Hello, Im trying to use the PUT (update) a Contact route ( https://developer.constantcontact.com/api_reference/index.html#!/Contacts/putContact ) with no success.  Here is the body I'm sending towards the route. { "contact_id": "********************", "first_name": "John", "last_name": "Doe", "job_title": "", "company_name": "", "birthday_month": 11, "birthday_day": 18, "update_source": "Contact", "created_at": "2010-02-20T20:15:28Z", "updated_at": "2024-06-26T20:04:15Z", "custom_fields": [ { "custom_field_id": "********************", "value": "Some Value" }, { "custom_field_id": "********************", "value": "Some Value" }, { "custom_field_id": "********************", "value": "Some Value" }, { "custom_field_id": "********************", "value": "Some Value" }, { "custom_field_id": "********************", "value": "Some Value" } ], "phone_numbers": [], "street_addresses": [ { "street_address_id": "********************", "kind": "test", "street": "test", "city": "test", "state": "test", "postal_code": "test", "country": "test", "created_at": "2014-06-21T22:26:01Z", "updated_at": "2023-09-28T13:12:39Z" }, { "street_address_id": "********************", "kind": "test", "city": "test", "state": "test", "country": "test", "created_at": "2014-07-08T18:01:48Z", "updated_at": "2014-11-11T00:23:48Z" } ], "list_memberships": [ "********************", "********************", "********************" ], "email_address": { "address": "johndoe@test.com" } }       Now if I don't include the "email_address" field I get as a response:  [{"error_key":"contacts.api.validation.error","error_message":"email_address is missing"}] but if I do include it I get: [{"error_key":"contacts.api.conflict","error_message":"Validation failed: Email already exists for contact ************"}] Am I doing something wrong? How do I actually utilize this endpoint. Am I missing something in the body? Thank you. ... View more
