Sometimes the API will have trouble validating. If this is the case, you will receive the following message from 'rPlant': "API Error, please retry". This only seems to occur in a new R session. If this occurs, please try the validation a second time. If it does not work the second time, then there may be a problem with your account.

These include, an access token (foundation) or an API consumer key and secret (agave), the expiration, the user name and password, and a few other variables. To see the entire list of environmental variables, see
The function will print the error "Authentication failed" if if fails. Sometimes the API will require a second validation, in which case 'rPlant' will report an error asking you to retry.
