# Completion Rate Targeting

The Yahoo DSP supports the `COMPLETION_RATE` targeting parameter for video line items. Use completion rate threshold targeting to define what percentage of impressions to be 100 % completed.

For example, if `completionRateThreshold` is set to 60, this will target impressions with a 60% probability or higher to be completed.

## Endpoint

he Yahoo DSP supports the `COMPLETION_RATE` targeting parameter for video line items.

```plaintext
/traffic/lines/{id}/targeting
```

Use the following HTTP methods.

- Use the `GET` method to retrieve the completion rate thresholds configured for the specified line.
- Use the `POST` method to apply the completion rate threshold targeting to a specified line.

## Required and Supported Parameters

The `targeting` resource is the standard Yahoo DSP resource for targeting consumers based on their profiles, behaviors and ad content.

This resource comprises multiple fields that enable you to specify line targeting across many types of targets, including the `COMPLETION_RATE` target type.
