here' s the tutorial: http://docs.oxwall.org/plugin-tuts:contact-importer if this is a plugin you're referring to . 

Also, the steps of configuring have changed a little. Now you need to go to Credentials section in order to register your app. And you will need SSL certificate for proper work of the plugin

not really familiar with this ross, can you guide me step by step please? i cant find the credentials as well, and how can i get that SSL cert? thanks

the tutorial provide step-by step instructions, if you follow the link in the tutorial, you'll see this, there's a credentials section, then follow the steps in the tutorial. 

and read this please: https://www.google.ru/?gws_rd=ssl#newwindow=1&q=where%20to%20get%20ssl%20certificate

if i follow the instruction, i need to register my app first right, and i need to go to credentials to register, so its create new client id? then after that where can i get that ssl cert? the instruction is different from the present screen of the link

Raymond, please remove the application you've created and create a new from scratch by carefully following the instructions described here: http://docs.oxwall.org/plugin-tuts:contact-importer#google
