Thanks for the tip. Let me know when it's deployed to Stu's 190 cluster or other 6.0.0 cluster and I'll test my ecl.

Note that since HTTPCALL returns a Row not a dataset, you have to add one level of indirection to get your code to work. That is, one more nested record level.

l_array := RECORD
dataset(l_rawissue) issues {XPATH('Row')}; //capture the array contents
END;

dshttp:=HTTPCALL( URL, 'GET','application/json', l_array, XPATH('/'));

This will be in the 6.0 platform release.

Any update on which release this feature (reading json via HTTPCALL, with http headers specified) will be available?

Thanks Drea, it's great to have an existing test case hitting an external service. Don't get that too often.
