Notification not received on my device

@themaayur you wrongly defined API ID and API KEY.


//Your OneSingal APP ID
define("APP_ID", "YOUR_APP_ID_HERE");
//Your Onesignal API KEY

Enter your API ID in the place of YOUR_APP_ID_HERE
Enter your API KEY in the place of YOUR_API_KEY_HERE

Ohhh, Got it thanks…I will check it out.

I have done that it’s showing error

But I have entered content in textbox.

@themaayur message should be any English language

As u can see in above screenshot everything is in English language.

@themaayur please check your blocks

Here are the blocks.

@themaayur check your set web1 url block it should be contents not content

Ohh Sorry my mistake, Btw Thanks for support.
But why is it showing white dot in icon. what if i will the default bell icon.

@themaayur if you want to use default bell icon make small_icon value to empty

If i want to fix a small icon so that i do not have to set it every time then what should i do?
