We employ a systematic and model-independent method to extract, from space- and time-like data, the η and η′ transition form factors (TFFs) obtaining the most precise determination for their low-energy parameters and discuss the Γη→γγ impact on them. Using TFF data alone, we also extract the η − η′ mixing parameters, which are compatible to those obtained from more sophisticated and input-demanding procedures.
