What are the URI/URL schemes for most IM networks?

Question

I am looking for information abou URI schemes for most used IM/chat networks and phone.

Looking for URI for

• phone number tel: - already solved, RFC 3966
• yahoo ymsgr:addfriend?yourid
• skype
• msn
• XMPP/Jabber/Google talk
• sip:[email protected], also used by Microsoft Office Communicator

Note, I know that Skype supports callme:// but I don't know if this is specific to Skype or where is the syntax described.

Rum

Don't assume the //. tel:, for example, doesn't use //. – Marley

Indeed, it's a schema-specific requirement. Solely the oldest of them use it still, since Berners-Lee doesn't like it (and it's a useless relic). – Rib

Answer 1

To anyone who still finds this relevant, here's what I gathered:

Service	Format
Email	mailto:<email>?[Subject|CC|BCC|Body]
Phone	tel:<number>
SMS	sms:<number>
IRC	irc://<url>:[port|channel|password]
FaceTime	facetime:<number>
Skype	skype:<username|number>?[add|call|chat|sendfile|userinfo]
Hangouts (formerly Google Talk)	gtalk:[chat|call]?<email> com.google.hangouts:[chat|call]?<email>
Windows Live Messenger (formerly MSN)	msnim:[add|chat|voice|video]?<email>
Yahoo! Messenger	ymsgr:[sendim|addfriend|sendfile|call|callPhone|chat|im|customstatus|getimv]?<email|number>
AIM	aim:[goim|goaway|addbuddy]?<username>
QQ	mqq://<url>
ICQ	icq:message?uin=<number>
Jabber, as already answered at https://mcmap.net/q/1670895/-what-are-the-uri-url-schemes-for-most-im-networks	xmpp:[email protected]

Does anyone know the URI for imo messenger? – Anastase

"Email" should be "E-mail", @Fox. – Rib
