Is it possible to send sensitive data to Sprig, as opposed to exposing it in our application and sending it through the Sprig SDK?

For any sensitive data that users do not want exposed or surfaced in their application, Sprig offers a REST API. The /users/ endpoint allows teams to create, or update, visitor records from your backend.

If the userId sent to the API does not already exist in the specified environment, a new visitor record will be created. If the userId already exists, any new data will be appended to that visitor record.
