Perfect, that's what I was looking for, And I would make my calls to the API there, build out a message and send the XML on to the DTL that adapts to HL7?

Hi thanks for the reply, this seems like the cleanest way and CRONs are a good option but our client won't accept external libraries 

Do you know what those DTL classes would be called? I've had a look but I couldn't see any reference to JSON DTLs in HealthShare HealthConnect 2021.1
Thanks, 
Ben
