I'm trying to post a plan via the Rest API Tempo Planner. I use the createPlan (postPlan) endpoint, but I continuously get a 'VALIDATION_FAILED' error.
I tested the authentication header I use with other API endpoints (such as getAllPlans) and there it works.
As request body I use the following. As assigneeKey I use the JIRA username, is this correct?
{ "assigneeKey": "firstname.lastname", "description": "Working hard on this issue", "start": "2020-11-04", "startTime": "09:00", "end": "2020-11-04", "day": "2020-11-04", "planItemType": "ISSUE", "planItemId": "4401", "secondsPerDay": 3600, "includeNonWorkingDays": false, "partialUpdate": true} What can I check to get this working?
