Skyline renders URL previews in text sends by default. Control preview generation with the richLink send option: 
// Preview enabled (default)
await space.send("Check this out https://interactions.co.in");

// Plain URL, no preview card
await space.send("https://interactions.co.in", { richLink: false });

​
iMessage behavior

On iMessage, link detection runs when scan is enabled (default). Disable both scanning and previews when you need a raw URL string: 
await space.send("https://example.com/secret-token", {
  richLink: false,
  scan: false,
});

​
Dedicated app cards

When you need a designed card instead of an auto-generated preview, send an App or Flow card with caption slots and artwork.
