The upsert endpoint is designed to allow Luadspeaker users the programmatic ability to add new customers or update existing customers.

The upsert endpoint looks up a customer document using the supplied primary_key, and then adds or changes customer attribute values specified in the properties json object in the request body.

In order to use this endpoint, a primary key must have first been selected via the Laudspeaker UI.
