Is there any method other than HTTP through which we can make SAP Concur communicate with Dell Boomi?
I do not know which technical solutions you can use to call you specific Concur version/installation from Boomi (outbound). I recommend checking the manuals of Concur for that. Next, check out the technology connectors of Boomi
You can build and deploy your own web services / API on the Boomi platform. Both REST and SOAP. These enable you to push data from Concur to Boomi and from there, to downstream endpoints.
