Is an online pūjā booked through a website or app valid?

yes, if a real priest performs it with your saṅkalpa and you join with devotion; it works best when you take part, not just pay.

Having a pūjā done on one’s behalf is an old custom: families have always sent money to a temple or a priest at a tīrtha to perform an abhiṣeka, homa or śrāddha in their name. The key element is the saṅkalpa, the formal statement of who the pūjā is for and why, with name, gotra and intention. An online booking that includes a genuine saṅkalpa follows this same principle.

To get the most from it, join the live stream or video call, sit before your own lamp at home, and respond to the steps with folded hands. Afterwards, do something yourself, such as distributing food or reading a prayer.

Be careful whom you book with: choose established temples or recommended priests, check reviews, ask whether you will see the pūjā live, and avoid anyone who promises guaranteed results.
