What or software tool are you trying to connect?
An API (Application Programming Interface) key is a unique alphanumeric code that authenticates your identity to 1fichier’s servers. Instead of logging in with a username and password every time, an API key allows scripts, applications, and third-party tools to interact with your account programmatically.
1fichier has servers in France (OVH) and Canada. Depending on your location, one is faster. Use curl -I on a test file to see the redirect. For US users, ensure your API requests route to the Canadian CDN by using a DNS resolver that returns the closest edge.
