We observed the impact of the finite magnetic field on the in-medium mass and decay constant of isospin averaged vector 
and axial-vector 
mesons. The quark and gluon condensates of the nuclear medium at the finite magnetic field, temperature, isospin asymmetry, and density have been obtained by the meson exchange scalar fields within the chiral SU(3) model. The medium attributes modify the scalar and vector density of the nuclear medium and this variation reflects in the in-medium mass and decay constant of spin 1 D mesons. We calculate these observables by comparing the Operator Product Expansion (OPE) and the phenomenological side in the QCD Sum Rules. In the results, we observed a positive mass shift for charged vector and axial-vector D mesons concerning the magnetic field. For neutral vector (axial-vector) D mesons we observed negative (positive) mass shift as a function of the magnetic field. In the application part, we calculate the in-medium partial decay width of the process 
(2715/2860) 
by using 
model. The in-medium effects are incorporated through the in-medium masses of 
and K mesons.
