An openfire expert needed (URGENT)

We have an Elastix installation (with Openfire v4.01) . We have already enabled some plugins. We are interested in RestAPI plugin which we believe is not sufficent for us. We need a script that can complete bellow tasks: 1 - Connection to the xmpp server 2 - Send a message to all the users in a specific group. 3 - Get Message Delivery Receipts for each user in the group The recipient can be any xmpp client that support XEP-0184 extension. We can provide xmpp server information and some accounts for testing. The script should be in python using SleekXmpp library (enabling XEP-0184 extension) AS Example: python [login to view URL] -jid "user@domain" -p "passwd" -d "groupName" explanation: jid : jabber identifer for the user sending the message. p: password d: destination, these a group of recipients. The Results (JSON) should be like: { "groupName":[ { "user":goup_user1@domain, "delivery":"confirmed" }, { "user":goup_user2@domain, "delivery":"confirmed" }, { "user":goup_user3@domain, "delivery":"confirmed" }, { "user":goup_user1@domain, "delivery":"confirmed" }, ..... etc ] }
