A questionnaire completion log is sent for every task to give information regarding the task's completion percentage. The schema is as follows:
|Name||String||Name of the questionnaire (e.g. ESM, PHQ8)|
|Time||Double||Timestamp in UTC (s) when the questionnaire completion log is submitted. A questionnaire completion log is submitted in two ways: along with a questionnaire when it is completed (100% completion) or when the questionnaire's completion window has expired before completion (0% completion).|
|TimeNotification||Double or Null||Timestamp in UTC (s) when the notification to complete the questionnaire/task is sent. This is the timestamp a questionnaire is supposed to be filled. This is null if no time notification is provided (e.g. for clinical tasks done in the clinic).|
|CompletionPercentage||Double or Null||Percentage of the questionnaire completed. 0 for not at all complete and 100 for full completion. Null if no completion value possible.|
Completion logs may also be listed for the Previous Day, when the Completion Window expires at midnight.
