I have never worked or heard of iMIS and or Litmos but I have worked on API based projects , built Custom CRM and ERP , and worked on LMS databases for the last 12 years ... now coming to this project
Can you please share the API document and can you tell me the following
1) What kind of a server do you have ?
2) What kind of API do you use ? REST or JSON ?
3) What kind of Cron-Job setup do you have ?
