  X-ray polarimetry is a powerful tool to probe the geometry of the hot X-ray
corona in active galactic nuclei (AGN). Here, we present our results on the
characterisation of the X-ray polarization of the radio-quiet Seyfert-type AGN
IC 4329A at a redshift of $z$ = 0.016. This is based on observations carried
out by the {\it Imaging X-ray Polarimeter (IXPE)}. {\it IXPE} observed IC 4329A
on January 5, 2023, for a total observing time of 458 ks. From the
model-independent analysis, we found a polarization degree ($\Pi_{X}$) of
3.7$\pm$1.5$\%$ and a polarization position angle ($\Psi_{X}$) of
61$^{\circ}$$\pm$12$^{\circ}$ in the 2$-$8 keV energy range (at 1$\sigma$
confidence level). This is also in agreement with the values of $\Pi_{X}$ and
$\Psi_{X}$ of 4.7$\pm$2.2$\%$ and 71$^{\circ}$ $\pm$14$^{\circ}$ respectively
obtained from spectro-polarimetric analysis of the I, Q and U Stokes spectra in
the 2$-$8 keV energy band (at the 90$\%$ confidence). The value of $\Pi_X$ in
the 2-8 keV band obtained from the model-independent analysis is lower than the
minimum detectable polarization (MDP) value of 4.5$\%$. However, $\Pi_X$
obtained from spectro-polarimetric analysis in the 2-8 keV band is larger than
the MDP value. In the 3-5 keV band, we found $\Pi_X$ of 6.5 $\pm$ 1.8, which is
larger than the MDP value of 5.5$\%$. The observed moderate value of $\Pi_{X}$
obtained from the analysis of the {\it IXPE} data in the 3$-$5 keV band argues
against a spherical lamp$-$post geometry for the X-ray corona in IC 4329A;
however, considering simulations, the observed polarization measurements tend
to favour a conical shape geometry for the corona. This is the first time
measurement of X-ray polarization in IC 4329A. Measurements of the X-ray
polarization in many such radio-quiet AGN will help in constraining the
geometry of the X-ray corona in AGN.
