@wang_Jehoo_Studio Here you can see how to use niotron’s inbuilt in app billing component :

i tried using the tutorial on the video, but when i click the button, it shows nothing, i even publish the app and set the in app subscription, still when the button get clicked, it shows nothing.

@wang_Jehoo_Studio Share your blocks screenshot. I will check if there is any problem or anything else


@wang_Jehoo_Studio Is the Play Store listing your app? If so, only this will function; if not, make use of the test payment IDs.

How can do the test payment id. because when i use the way it was done on the tutorial, it shows nothing. no test

You can’t test the subscription product without uploading the app into console. At least you might upload it into internal testing.

@wang_Jehoo_Studio, see this, as I already said:

Its shows nothing, even error is not showing

I think the in app billing is not connecting because i use the error blocks to get some response to know whats the issue but nothing is showing
