So for whatever reason I have a mental block distinguishing between these two when it comes to the Taleo API. So to finally write it down:

  • TCC uses ‘asynchronous’ transactions (it processes transactions in a queue) while the Taleo Web Services is ‘synchronous’.  
  • The Taleo WebServiceAPI is type Simple Object Access Protocol (SOAP) for XML-based message exchange, not Representational State Transfer (REST).
  • Taleo Web Services is designed for smaller integrations.  
  • The integration limits of each are covered in the appendix of their respective user guides.
  • For more information about the Taleo integration tools and their limits please see:
