The 401 error is an authorization error. Without knowing much it suggests your app wasn’t deployed in a way that a data source could authenticate your app.

Where’s the data coming from the app?

In terms of a general docs on connecting a shinyapps.io app to a database, check out https://docs.rstudio.com/shinyapps.io/applications.html#accessing-databases-with-odbc

The data is coming from an external source for the app. I get the data using an api to an internal database we have.

TOKEN="XXXXXXXXX"
basic_url = "https://app.collaborativedrug.com/api/v1/vaults/5177/"
base_url = paste0(basic_url,"protocols")
run_url_individual = paste0(basic_url,"runs/")
slurp_url = paste0(basic_url,"slurps")
response<-GET(base_url, add_headers(.headers = c("X-CDD-Token"=TOKEN)))
request <- stop_for_status(response)
print(request)
http_type(response)
get_protocols_json <- fromJSON(content(response, as = 'text'))

Snippet of how i am getting the data
