Mapping EOL species with GBIF species

Hello,
I develop an application which is using https://opendata.eol.org/ data as a source of data for my own database. Also, we highly use GBIF data. I wonder if there is an unambiguous way to determine mapping EOL species with the GBIF counterparts. Like View this species on GBIF on EOL species pages.
If there is no such reference in opendata datasets, maybe it is possible to get GBIF taxonID/nubkey using EOL API?
