What are the different methods to invoke any process from the outside of Appian.

Sonal, you can publish your process model as a Web Service and then invoke it by a Web Service call.

For more information about that, please go through our documentation from the sub-sequent link:

forum.appian.com/.../Publishing_Process_Models_as_Web_Services

You can also use emails and JSM to start processes. For more information on how to configure a process to do this please visit: forum.appian.com/.../Start_Event:_Receive_Message.

I am not able to access following links, its bringing me back on forum.appian.com/.../

Sonal - Please relogin to Appian Forum again and you should be able to access the documentation links mentioned previously.
