# How to Register for LSEG / Refinitiv (Pro)

This feature requires the Pro version of the Taxonomies plugin

The TaxoPress Auto Terms feature has an integration with the LSEG / Refinitiv / OpenCalais API service.

The TaxoPress team is not responsible for the quality of results from LSEG. This platform has changed names several times and is mainly included in TaxoPress as a legacy feature.

Please also note that registering for an API key can be a complex and confusing process. We'll do our best to walk you through the steps. Getting an API key requires registering at one site and using those login details for a second site.
