The IEC Partner Administration Tool has a function that you can use to test M3
API connection.
Open the IEC Partner Administration Tool.
Click Manage > Communication.
Click M3 API tab panel.
Select your preconfigured M3 API connection or create a new
one.
Click Test to determine if your M3
API connection works or not.
The locality or the machine where the Partner Administration Tool or the
MEC server is located, is an important factor which affects the connectivity of
the M3 API. The locality and proximity does not mean that the Partner
Administrator M3 API test is always successful and the MEC server M3 API is
always functional. The Partner Administrator Tool and MEC Server programs being
in different machines play a factor in successful connectivity.
