# Create a benefit enrollment

> Start a worker's run through an enrollment event.

Open a worker's run against an [event](/reference/benefit-events/object). The
enrollment starts in `not_started`. There is one enrollment per worker per
event — creating a second for the same pair returns an error.

### Parameters

<ParamField body="worker" type="string" required>
  ID of the worker whose run this is.
</ParamField>

<ParamField body="event" type="string" required>
  ID of the [event](/reference/benefit-events/object) the run is under.
</ParamField>

<ParamField body="metadata" type="object">
  Set of key-value pairs attached to the enrollment.
</ParamField>

### Returns

Returns the created [Benefit enrollment object](/reference/benefit-enrollments/object).
