  1. 1
    Sign in to SNCF
    Open https://numerique.sncf.com/startup/api/ and sign in to the account you want to connect.
  2. 2
    Create the API key
    Open https://numerique.sncf.com/startup/api/token-developpeur/ and generate a new API key.
  3. 3
    Copy it immediately
    SNCF usually shows the full API key only once, right after you create it. Store it somewhere safe before closing the page.
  4. 4
    Connect in Verslay
    In the Verslay Hub, open Connections, find SNCF, and paste the API key into the SNCF Developer Token field.
  5. 5
    Verify
    The connection flips to Connected. Run any read-only action once to confirm the credential has the right scopes.
  6. 6
    Rotate safely
    When you rotate later: connect the new credential first, confirm it works, then revoke the old one.
