Abstract It is crucial to determine the spin and parity ($J^{P}$) of ${Z_{\rm c}(3900)^\pm}$ for understanding its structure. We perform a helicity amplitude analysis on ${Z_{\rm c}(3900)^\pm}$ in the process ${e^+e^-}\to\pi^+\pi^-{J/\psi}$ with the hypotheses $J^{P}=0^-$, $1^+$, $1^-$, $2^+$ and $2^-$. To estimate the significance of $J^{P}=1^+$ over other hypotheses, we perform a Monte Carlo simulation study, and we also discuss the prospect of measuring the spin parity in the future experiment with a large data sample.
