Go to EAM Administration | Security | Install Parameters screen and locate AXISURL install parameter. Copy the value of this install parameter to any text editor and then replace "services/EWSConnector" with "imsservice". The result will be the EAM IMS end point URL.
For example, when AXISURL="https://hexdev.eamade.hxgnsmartcloud.com/axis/services/EWSConnector",
EAM IMS URL will be "https://hexdev.eamade.hxgnsmartcloud.com/axis/imsservice".
