    Create the API key
    Generate a new API key from the API or developer settings in your Polygon dashboard.

    Copy it immediately
    Polygon usually shows the full API key only once, right after you create it. Store it somewhere safe before closing the page.

    In the Verslay Hub, open Connections, find Polygon, and paste the API key into the Polygon API Key field.
  5. 5
    Verify
    The connection flips to Connected. Run any read-only action once to confirm the credential has the right scopes.
