The only required parameter for this endpoint is a user identifier, which may take the form of one of the following (which is also the order of precidence if multiple identifiers are provided)

User ID - An internal Maptician userID value for the target user.
Email Address - A case insensitive email address value which must match the email for the user within Maptician.
Employee ID - A case sensitive string representing the employee's employee ID as entered within Maptician.
External ID - Not common, but Maptician users may be mapped to external systems using an external ID value.
Employee Name - Least preferred due to risk of ambiguity and alternative spellings, a first and last or name parameter may be used to search for a user based on their name within Maptician.

If no time value is provided, the current time will be used based on when the request was received. A time parameter can be provided, in addition to a date parser format which will be used to attempt to parse the provided date value (default is ISO_8601). By default, the time of the presence status and reservation will start from the provided time / current time, but optionally, a "full day" parameter can be passed to attempt to use the full calendar day values for start and end.
