ReqRes offers three API key permission levels: read-only (GET only), read/write (GET, POST, PUT, PATCH), and manage (includes DELETE operations). Use admin keys for managing collections and automations; use session tokens for per-user data access.

Fetching JSON data from REST APIs
Below an example from the ProPublica Nonprofit Explorer API where we retrieve the first 10 pages of tax-exempt organizations in the USA, ordered by revenue. The rbind_pages function is used to combine the pages into a single data frame. #store all pages in a list first baseurl <- "https://projects.propublica.org/nonprofits/api/v2/search.json?order=revenue&sort_order=desc" pages <- list() for(i in 0:10){ mydata <- fromJSON(paste0(baseurl, "&page=", i), flatten=TRUE) message("Retrieving page ", i) pages[[i+1]] <- mydata$organizations } #combine all into one organizations <- rbind_pages(pages) #check output nrow(organizations)
