Delete a customer

​

Deleting a customer removes them, and all of their information, from Customer.io.

NOTE: Calls that update customers by ID can also create a customer. If you send data to Customer.io through other means (like the Javascript snippet), after you delete a customer, you may accidentally recreate the customer. You cannot delete a customer using the Javascript snippet alone.

Path Parameters
  • identifier
    required

    The unique value representing a person. The values you use to identify a person may be an id, email address, or the cio_id (when updating people), depending on your workspace settings. When you reference people by cio_id, you must prefix the value with cio_.

    You can't reference a person by their phone number here. We determine the identifier type from the shape of the value, so a phone number in the path is treated as an id. To identify people by phone number, use the Track v2 API.

    • Type: string · id

      The unique identifier for a person that you want to create or modify.
