当用户单击我网站上的 html 按钮时，如何将联系人保存到 Android/IOS 电话簿（联系人应用程序）

Question

I am trying to make a website where a user can click a button or click a link and it opens the phone's native Contacts app and fills in provided information from the website. I spent my day doing research and couldn't find useful information. I found out the below line about Deep Links, where I can put

<a href="instagram://user?username=instagram">Link</a>

and this opens the Instagram app on my phone. I am assuming I need something like this to open the Contacts app.

Answer 1

Unfortunately, we don't have any available deep link to open Contacts app. Apple provide the CNSaveRequest APIs to update/add/delete contact without using interface but I don't know anyway to access this API from website
