Trying to migrate to the CMX 10.3 as we need AeroScout tag data and have run into a bug with 8.x where I am losing random tag data for hours at a time. We went to convert our integration tool to the 10.3 instance but found the REST API in 10.3 is not accepting the application/xml format. Was XML droped in CMX 10.3 REST API's? Hoping the answer is no because otherwise we need to rewrite our integration application.
Maybe only Streaming notification JSON/XML are support. I see in the release notes for CMX 10.1 under Standards Based REST API the following, "Input and output of API uses the standard JSON format." That would indicate only JSON.
I apologize for not knowing this for sure, and will reach out the the CMX BU folks for verification.
