[CameraKit Web SDK](../globals.md) / LensSource

# Interface: LensSource

Provides Lens metadata for one or more Lens groups.

When a Lens or Lens group is requested via the [LensRepository](../classes/LensRepository.md), CameraKit will find the LensSource which
claims ownership of that group. The appropriate LensSource method will be called and must return an ArrayBuffer
containing the encoded Lens metadata -- this can be obtained from a CameraKit backend API.
