Recently, upper bounds on the static time-reversal (T) and spatial parity (P)-violating electron electric dipole moment (eEDM) and dimensionless constant characterizing the strength of the T,P-violating scalar-pseudoscalar nucleus-electron interaction have been updated in the JILA experiment using the HfF+ cations [T.S. Roussy et al, arxiv:2212.11841 (2022)]. We considered other two sources of the T,P,-violation in HfF+ -- axionlike-particle-mediated (ALP) scalar-pseudoscalar electron-electron and nucleus-electron interactions. To estimate the magnitude of effects, induced by such interactions in HfF+ we have developed and applied a method which implies direct use of the ab-initio relativistic coupled cluster theory to calculate molecular parameters that characterize the interactions. Using these parameters, we showed that an order of magnitude updated laboratory constraints on the ALP-mediated electron-electron and nucleus-electron interactions can be derived from the experimental data on T,P-violating effects in HfF+ for a wide range of ALP masses.
