在 iOS 上使用 Whatsapp url scheme 调用

Question

We can open conversation/chat window for WhatsApp by using URL Scheme:

        if schemeAvailable("whatsapp://")
    {
        UIApplication.sharedApplication().openURL(NSURL(string: "whatsapp://send?abid=68")!)//68 is the example, addressbook contact id
    }
    else
    {
        UIApplication.sharedApplication().openURL(NSURL(string: "https://itunes.apple.com/app/whatsapp-messenger/id310633997")!)
    }

I want url scheme to start call? I not found any documentation or reference for it either on WhatsApp official page or on any blog. Can we do this or its not possible?

Answer 1

Currently Whatsapp doesn't have URL Scheme for Call feature.

But it does have custom URL scheme to chat with a specific contact.

You can use the following url to directly open contact and use

on whatsapp to any contact number
