text: We have a requirement where we just need to change the chat & email channel's state using the below APIs but it's somehow not working.
  I am attaching the Postman screenshot for reference.
  Could you please check if we are missing anything?
  Thanks in anticipation.
  What system are you using.
  The API is for UCCX, but the label for the question is for UCCE
  What version is the sytem ?
  Normally it looks like this
  Use the API
  We are using Sandbox Lab - Unified Contact Center Express 12.5.
  For this environment, is below API URI valid ?
  But its failing, attaching the Postman screenshot.
  So it is an UCCX enviroment...
  Media Routing Domains (MRD) is an UCCE/PCCE feature, so that will not work.
  I actually don't think you can change the nonvoice state thrue REST on a UCCX (Maybe i'm wrong)
