+# "Authentication"
+- The VL-api requires some headers to be set:
+- The ```Referer``` header has to be set to ```https://ifsc.results.info/```
+- The ```x-auth-token``` header has to be set to ```cc7375f680648e7e6171e035e70351eb```
+- For easy use, a browser plugin can be used to inject the header automatically, [this one](https://addons.mozilla.org/en-US/firefox/addon/modify-header-value/) worked just fine for me on Firefox.
