Just need a small support I am trying to do a data transfer between angular application and iOS/Android. I have native android and iOS application on the other side I am using angular 12 application. what I suppose to do is to send data to angular application from android/iOS native application and vice versa. I am able to pass data by using "Query String" but query string have there limitations. what I have to do I have to pass data via headers or any other secure method. Just need a quick guidance from Stackoverflow community
