Caveats

Some notes on the start_date and end_date query parameters:

  • they are both required and should represent ISO 8601 formatted dates
  • end_date must be greater than or equal to start_date
  • end_date cannot be more than 365 days in the future from start_date

Note: you can update schedules affecting past events, which will then change the output you get from this endpoint. To get consistent information about past shifts you must be sure to avoid updating rotations in-place but apply the changes as new rotations with the right starting dates.

Example script to transform data to .csv for all of your schedules

The following Python script will generate a .csv file, oncall-report-2023-01-01-to-2023-01-31.csv. This file will contain three columns, user_pk, user_email, and hours_on_call, which represents how many hours each user was on call during the period starting January 1, 2023 to January 31, 2023 (inclusive).
