  Carrollian amplitude is the natural object that defines the correlator of the
boundary Carrollian field theory. In this work, we will elaborate on its proper
definition in general dimensions. We use the vielbein field on the unit sphere
to define the fundamental field with non-vanishing helicity in the local
Cartesian frame which is the building block of the Carrollian amplitude. In
general dimensions, the Carrollian amplitude is related to the momentum space
scattering matrix by a modified Fourier transform. The Poincar\'e
transformation law of the Carrollian amplitude in this definition has been
discussed. We also find an isomorphism between the local rotation of the
vielbein field and the superduality transformation.
