*In this talk, we will cover elements of supersymmetric scattering. The S matrix is an onshell process with free incoming and free outgoing states. We construct onshell representation of $\mathcal{N}=1$ supersymmetry and ward identities for the S matrix in superspace. The various supersymmetric processes be compactly encoded in a superspace S matrix. The ward identities for the S matrix relate six of the eight possible processes in terms of two independent functions. Further constraints from $\mathcal{N}=2$ theory relates these two independent functions as well. Further building on these results,*

we outline the construction of unitarity equation using the superspace S matrix.
