Deletes the contact identified by the contact_id path parameter. Deleted contacts won't receive email from you, and they don't count as active contacts. Unlike unsubscribed contacts, deleted contacts can be revived, or added back to an account. Learn how to revive deleted contacts.

This endpoint GETs a specific contact resource (contact_id). Use the include query parameter to add any of the available contact sub-resources to the response payload.

The PUT method updates an existing contact. You must include the update_source property in the PUT request payload. To restore a deleted contact you must specify the update_source as Account. When updating any resource using PUT, all properties are updated, overwriting all previous values. Any properties left blank or not included in the request are overwritten with null value - however this does not apply to contact subresources. Add or change any of the subresources by including them in the PUT request payload. Omitted subresources are not overwritten with null. If the contact being updated is deleted, the contact will be revived.
