Pass search parameters along with SSO login
I have a unique situation where the Pega Customer Service application is embedded into an external website (not as a mashup) but the entire application is embedded. On the external site, the member search as well as member 360 information is all fetched and when the CSR needs to be perform certains tasks, they will click on a link which will launch Pega application in an iFrame and the URL used is the SSO url so the user is automatically logged into Pega. The client does not want to perform another Member Search inside of the launched Pega application since the external site has performed all of this.
The question I have is, is there a way that I can pass in the Member ID while I am calling the SSO url. If I do a mashup, there are ways to pass in params, is there a similar approach when the full application is embedded in an iFrame.
