Testing CDS Hooks service with encounterId in context

[Barbara Atkins]

Hi!

Is there a way to test an CDS Hooks service endpoint while simulating an encounterId value?  I was looking at the Launch Scenarios in Logica sandbox and it seemed as though I coul specify an Encounter Id value and have it passed on on launch, but the encounterId value specified is not coming through.   Have others used this tool successfully in this way?  If so, any pointers? Are there any other sandboxes to test CDS Hooks services?

I've included screenshots of the config & the request to my service.  I'm wondering what other configuration I would need to do to include encounterId in the context block.  

Thanks in advance for any help.

Thanks,
Barbara
