Using RapidAPI’s R example for historical data returns a 401 error. How can I correctly format my API call?
library(curl)
api_endpoint <- 'data_endpoint'
params <- list(ticker = 'ABC', region = 'NA')
result <- curl_fetch_memory(api_endpoint, handle = new_handle(httpheader = c(RapidKey = 'secretKey', RapidHost = 'apiHost')))
hey, i got similar error and solvd it by double-checking your header cases and extra space in your keys. sometimes rapidapi requires exactly ‘x-rapidapi-key’ and ‘x-rapidapi-host’ in lowercase. try that and see if it fixes the 401 error. hope it helps!
I encountered a similar problem a while ago and ended up realizing that the error was partly due to the endpoint URL formatting as well as the header case sensitivity. In my case, checking the API documentation showed that the RapidAPI platform sometimes expects a different structure to the URL, like an additional trailing slash or slight changes in the base path. I also confirmed that the header names had to match exactly what the docs specified. After modifying both the URL and adjusting the header key names, the API call worked as expected.
I faced a nearly identical issue previously. My solution involved verifying the endpoint URL structure and ensuring the header names matched exactly what the API documentation required. Although initially it appeared that my authentication key might be the problem, I eventually discovered that a minor discrepancy in the header capitalization was to blame. I adjusted my code to use the exact header names and checked for any added spaces in the key values. Additionally, I confirmed the endpoint syntax was correct, including any mandatory trailing slashes. Once these adjustments were made, the API call was successful.
hey, check if your endpoint actually requires an extra slash at the end, sometimes it does. i had similar issues and missed that. also double check if your rapidapi key is passed without any extra spaces. might be a small, but key issue.
