To set up a connection to the Species+/CITES Checklist API, an authentication token is required. Each user should obtain his or her own personal token to run the code below (see https://api.speciesplus.net/documentation for more details). To obtain a token, sign up on the Species+ API website.
Now, we assume that you already have a token. For illustrative
purposes, we will use the generic token value
8QW6Qgh57sBG2k0gtt from the API documentation.
A token is mandatory and needs to be passed to the header of all URL
requests. They are three different ways to set the token in
rcites:
set an environment variable SPECIESPLUS_TOKEN in
your .Renviron
file (preferred for frequent users);
use set_token() to set up the token as a character
string (with quotes). If not entered in the function, the token can be
passed without quotes (not as a character string) after the prompt. This
way, the token SPECIESPLUS_TOKEN is interactively set up
only for the current R session, meaning a login will be required for the
future R sessions (preferred);
token argument inside the functions,
i.e. the token is passed manually to each function call.Note that if you set a wrong token and you wish to set it again
interactively, you must first forget the previous token with
forget_token().
In order to efficiently query information from the CITES database,
you first need to retrieve the unique taxon identifier
taxon_id from the Species+
taxon concept. To do so, you should first call
spp_taxonconcept() and provide the scientific name of the
taxon you are looking for. Let us start by requesting the identifier of
the African bush elephant, i.e. Loxodonta
africana.
Note that if you have decide to set your token using the third option, then the code should look like the one below:

use the active taxon identifier of a given species. For

indicated in the table below:
