+You can set the processing guarantees for a Pulsar Function when you create the Function. The following [`pulsar-function create`](reference-pulsar-admin.md#create-1) command creates a function with effectively-once guarantees applied.

 > By default, Pulsar Functions provide at-least-once delivery guarantees. So if you create a function without supplying a value for the `--processingGuarantees` flag, the function provides at-least-once guarantees.
