SSRS -SQL Server Reporting Server 

SQL Server Reporting Services provides access to the full functionality via  Report Server Web service. The Web service uses Simple Object Access Protocol (SOAP) over HTTP and acts as a communications interface between client programs and the report server.

Here is the URL  to access Reporting Server Web Service.

http://<YourServerName>/reportserver/reportservice.asmx

when your browse the  Reporting Server Web Service you get the  List of Methods which exposed.

Using this Reporting Service WebMethod  i am going to call reports and Send as PDF format as Email Attachment.
