Ceridian Dayforce and Taleo TBE integration

Summary: We are looking to integrate out HRIS Ceridian Dayforce to our ATS Oracle Taleo TBE. I had some questions on how to get this started to anyone who has gone through this:

• Which Taleo API's or connectors did you use and how did that work?
• What data transfer method is preferred or worked well for you?
• How did you deal with existing Taleo integrations such as background checks, etc.? Was there a disruption? If not, how did you avoid a disruption?
• How frequently do you sync your data between the two systems? Real-time? Hourly? Daily?
• Do you use a middleware or iPaaS platform for integrations? How does that work?
