The WZ production cross section is measured in proton-proton collisions at a centre-of-mass energy $$\sqrt{s} =$$ 13 TeV using data collected with the CMS detector, corresponding to an integrated luminosity of 35.9 fb$$^{-1}$$. The inclusive cross section is measured to be $$\sigma_{\text{tot}}$$(pp $$\to$$ WZ$$)$$ = 48.09 $$^{+1.00}_{-0.96}$$ (stat) $$^{+0.44}_{-0.37}$$ (theo) $$^{+2.39}_{-2.17}$$ (syst) $$\pm$$ 1.39 (lumi) pb, resulting in a total uncertainty of $$-$$2.78/$$+$$2.98 pb. Fiducial cross section and ratios of charge-dependent cross section measurements are provided. Differential cross section measurements are also presented with respect to three variables: the Z boson transverse momentum $$p_\mathrm{T}$$, the leading jet $$p_\mathrm{T}$$, and the $$m$$(WZ) variable, defined as the invariant mass of the system composed of the three leptons and the missing transverse momentum. Differential measurements with respect to the W boson $$p_\mathrm{T}$$, separated by charge, are also shown. Results are consistent with standard model predictions, favouring next-to-next-to-leading-order predictions over those at next-to-leading order. Constraints on anomalous triple gauge couplings are derived via a binned maximum likelihood fit to the $$m$$(WZ) variable.
