# Using podcast trackers

Third-party podcast trackers uses the HTTP redirect functionality so that any request for an audio file goes to their servers first, before redirecting back to our servers. This allows them to track when a file is requested by an end-user, while redirecting back to our platform to serve the actual file.

Our platform supports these podcast tracking platforms:

- [Podtrac](http://analytics.podtrac.com/)
- [OP3](https://op3.dev/)
- ~~[Chartable](https://chartable.com/)~~ *(Deprecated - October 2024)*

## Enabling trackers

To enable this functionality, use the "Settings" button on the main [Podcasting](/v1/docs/publisher-dashboard-podcasting-overview) page of the publisher dashboard.

## Updated output

After saving this configuration, the tracker prefix(es) will **automatically** be inserted for all podcast URL's:

- In our web player.
- In RSS feed `enclosure` fields.
- In "download" links on our website.

For example, an `enclosure` in the RSS feed may look like something this without any tracker enabled:

`https://dl.iono.fm/epi/prov_1/epi_123_medium.m4a`

But after enabling Podtrac and inserting a Chartable ID, it will be updated to:

`https://dts.podtrac.com/redirect.m4a/dl.iono.fm/epi/prov_1/epi_123_medium.m4a`

## OP3 tracker

We also support the OP3.dev tracker, a free and open-source podcast prefix analytics service committed to open data and listener privacy. It works similar to our existing Podtrac and Chartable support by adding a prefix to all audio URLs.

It is enabled under the Podcast 2.0 section of the publisher config.

          
          

❗OP3.dev prefixes will only be added on shows that are linked to PodcastIndex.
