The measurement of the Higgs boson production for the two photon decay channel with the first LHC \textrm{Run}~2 data is described. The analysis is performed using the dataset recorded by the CMS experiment at the LHC from pp collisions at centre-of-mass energy of 13~\textrm{TeV} corresponding to an integrated luminosity of 2.7~\textrm{fb}^{-1}. An event classification has been performed to maximize signal significance and to study specific Higgs boson production modes. The observed significance for the standard model (SM) Higgs boson is 1.7~\sigma, where a significance of 2.7~\sigma is expected. The best-fit signal strength relative to the standard model prediction is $0.69^{+0.47}_{-0.42}$. Additional measurements include the signal strength associated with different production mechanisms.
