I'm trying to create a link to start a conversation on whatsapp from my react native app, but the method Linking.canOpenURL() is allways retuning false...

My code is the following:

const url = `whatsapp://send?phone=${celNumber}`;
Linking.canOpenURL(url).then(supported => {
    if (supported) {
        Linking.openURL(url);
    } else {
        Alert.alert(
            'Alert',
            'WhatsApp is not installed',
        )
    }
});

If I try to put some other url like tel:${celNumber} it returns true, so I think there is some problem with whatsapp url and canOpenURL(), since the whatsapp url works with the method Linking.openURL()...

I quess you are using iOS? Then you have to declared the URL’s scheme 'whatsapp' in your Info.plist file LSApplicationQueriesSchemes.

iOS9: canOpenURL returning false for WhatApp's url scheme
