I would suggest to read this doc https://network.informatica.com/onlinehelp/IICS/prod/CAI/en/index.htm
This would help you to understand to with Salesforce app connection or Managed Package.
At the end you need to have connection name as 'Salesforce'.
You need to understand/see direction of utilization of CAI w.r.t Salesforce.
so lot to know from your company point of view of IICS first. Your PAM might guide you more.
thanks for links ,
i) Concern is business team donot want to use salesforce app connection .
ii) even Salesforce Managed Package which is mandatory (i believe to establish connection with Informatica CAI) is not available / installed / configured .
so in such case what are the options from Informatica CAI side to connect to Salesforce app / crm ?
i believe , Salesforce CRM (especially Streaming API) works on Push Technology - pushing events to external systems
and Informatica as tool work on Pull Mechanism .
Let me know if i understood correctly
If you would like to connect to Out Of the Box SFDC connection, you must install the managed package in Salesforce.
In order to connect to SFDC using the custom Service connector, please use the following article : Support
