  We present the first measurement of the Timelike Compton Scattering process,
$\gamma p\to p^\prime \gamma^* (\gamma^*\to e^+e^-) $, obtained with the CLAS12
detector at Jefferson Lab. The photon beam polarization and the decay lepton
angular asymmetries are reported in the range of timelike photon virtualities
$2.25<Q^{\prime 2}<9$ GeV$^2$, squared momentum transferred $0.1<-t<0.8$
GeV$^2$, and average total center-of-mass energy squared ${s}=14.5$ GeV$^2$.
The photon beam polarization asymmetry, similar to the beam-spin asymmetry in
Deeply Virtual Compton Scattering, is sensitive to the imaginary part of the
Compton Form Factors and provides a way to test the universality of the
Generalized Parton Distributions. The angular asymmetry of the decay leptons
accesses the real part of the Compton Form Factors and thus the D-term in the
parametrization of the Generalized Parton Distributions.
