From the agile CRM doc, trying a few simple curl calls like this one (anonymised):
curl https://****.agilecrm.com/dev/api/contacts/*********** -H "Accept :application/xml" -v -u ********@***********:********************
And always same problem :
< HTTP/1.1 500 Internal Server Error
< Date: Mon, 29 Feb 2016 15:10:50 GMT
< Content-Type: text/html; charset=UTF-8
< Server: Google Frontend

< Alt-Svc: quic=":443"; ma=2592000; v="30,29,28,27,26,25"
<
Difficult to imagine any error in something that basic, but it doesn't work. Any idea?
