How to set goals in Yandex Metrica?

Question

Yandex.Metrica

You need to set a payment goal.
When the user clicks to pay (this can be fixed), but the result of the payment will come to the callback, which processes php.
How do I set the goal of the metric if it is running on js (on the client). And I need to set a goal for a positive result of payment (it can be different). connect nodejs? Long and tedious for one line yaCounter44292124.reachGoal('TARGET_REG');
Perhaps there is some simple solution, like making a redirect to the page with this js in the callback if the payment was made successfully?

Answer 1

After making a payment, does the user get to some page where the tariff / service is activated and / or a notification is displayed about the successful crediting of the payment?
If yes, then just on this page output yaCounter44292124.reachGoal('TARGET_REG'); and that's it, you don't need any php or nodejs

Answer 2

It seems like there is still no normal API for data transfer. The Yandex blog recommends transferring via offline conversions
