In this paper we present the all-loop conjecture for the integrands of Wilson line form factors, also known as the reggeon amplitudes, in SYM. The key role is played by a new gluing operation in momentum twistor space, which is used to derive the BCFW recursion for the loop integrands of the reggeon amplitudes.
