Update customer

PUT /v2/customers/{customer_id}

Updates a customer profile.

This endpoint supports sparse updates, so only new or changed fields are required in the request. To add or update a field, specify the new value. To remove a field, specify null and include the X-Clear-Null header set to true (recommended) or specify an empty string (string fields only).

As a best practice, include the version field in the request to enable optimistic concurrency control. If included, the value must be set to the current version of the customer profile.

To update a customer profile that was created by merging existing profiles, you must use the ID of the newly created profile.

You cannot use this endpoint to change cards on file. To make changes, use the Cards API or Gift Cards API.
