SAP Concur API xml

[bellizia_pwc]

Good morning,

I'm trying to use Concur API to extract information about Financial Posting.

Is it possible to extract them in XML format? I tried $format=xml and header with Accept: application/xml but these API return error or JSON only.

I'm trying to use them on CPI Enrich component instead to Splitter-Request-Gather way.
