What is it that I am missing here. I like to send scheduled notifications. See the block I have already but they dont seem to work.
So a time input is neeted.
A nother thing is that I need to delete scheduled notification if the appoinment is deleted. How do I do that??
What type of error you are getting?
You have not shown the URL for the OneSignal API but I assume you have coded it but not part of your screenshot, am I correct?
[Update] if I’m not mistaken, the block you are using was designed by @drted and he would be the one to let you know if anything is wrong in it at a glance.
It sounds like there is a problem with the user list.
Try replacing the include_player_ids with a list with just the GetUserID property of One Signal.
I found the blocks were very touchy, so I would remove the URL and header settings from the web API properties. I don’t know what the authorization header does, but it could be a problem. Again, that SHOULD be replaced by your blocks, but stranger things have happened with Thunkable.
