Taleo Scheduling Center Invite info for TCC Script

Hello,

We are in the process of creating a TCC script to identify the candidates who has been sent an Taleo Scheduling Center invite. As we would like to send those candidate details to our text vendor to send a text message along with email that goes to candidate email from scheduling center.

We are in need of information if there is a way to identify the candidates who has been sent calendar invite using TCC as we only see the data on the history tab that email correspondence is sent.

Thanks

Guru
