Elevent supports guest checkout, both online and through the box office. However, when system integrators request from the API all recent activity under customers, these anonymously-purchases items aren't included in the response.

We've added a Get All Anonymous Orders call to the API to round out the full picture of tickts and donations sold, to known customers and no one in particular.

This anonymous data is already retrieved by the Elevent for Salesforce app, to help complete your progress reporting against your campaigns and goals.
