Several approximations are commonly made when studying transfer reactions with ${}^8\mathrm{B},$ in particular, those used for extracting astrophysical information. We study the influence of the spin and deformation of the ${}^7\mathrm{Be}$ nucleus on the asymptotic normalization coefficients extracted from the reaction ${}^{14}\mathrm{N}{(}^7\mathrm{Be}{,}^8\mathrm{B}{)}^{13}\mathrm{C}$ and find that it has little influence in the value of the extracted astrophysical S-factor $S_{17}\mathrm{}\left(0\right).$ We also discuss the weak continuum effects found for this reaction under the light of new breakup calculations.
