Throw appointments to others with the LINE WORKS calendar API

The calendar API is new in LINE WORKS v2.7. I would like to actually use it while introducing the changes.

Calendar API type

Currently, there are two main calendar APIs.

Previous (~ v2.6) calendar API

There are two main types of LINE WORKS APIs: server APIs and service APIs.

Until now, the calendar API was provided only as a service API. Therefore, it was only possible to operate your own calendar with your own authority.

From now on (v2.7 ~) calendar API

Along with the v2.7 update, a new server API has been added that can be used for data copying during migration. However, at this time, the functions provided are limited.

Features provided by the calendar server API

--Create / delete calendar --Create / change / delete appointment

Key features not provided by the calendar server API

--Inquiry / correction of calendar information --Calendar list query --Inquiry of the schedule list in the calendar --Inquiry of schedule details

In this way, you can use "create a new calendar and throw it in", but "reference existing information" will continue to be limited to the service API.

Try using the calendar API

Using the new API, let's register a calendar and add an appointment. The following uses Python 3.8.0.

Creating a calendar

Click here for the API description. Creating a calendar

calendarlist.py

import json
import requests
import urllib.parse

APIID="API ID obtained from the Developer Console"
SERVER_CKEY = "Server Consumer Key obtained from Developer Console"
SERVER_TOKEN = "Server authentication token"

def CalendarlistS(ServerTOKEN,AccountId,**CalParams):
    #Creating a request URL
    apiurl =  'https://apis.worksmobile.com/r/'+ APIID + 'calendarList/'+ urllib.parse.quote(AccountId) + '/calendarList'
    
    header = {
        'consumerKey': SERVER_CKEY,
        'Authorization': 'Bearer ' + SERVER_TOKEN,
        'Content-Type': 'application/json'
    }
    #Pass CalParams as a calendar setting
    r = requests.post(apiurl, headers = header, json = CalParams)
    return r

#Creation example
cal=CalendarlistS(SERVER_TOKEN,'demo@exampletenant',name='demo calendar',description='hogehoge')

#The created calendar ID goes into returnValue
Cal_ID = cal.json()['returnValue']

Note that many other APIs use the value externalKey to specify members, but the calendar API accountId is in ID @ domain format.

Add appointments to your calendar

Next, register the appointment in the created calendar.

calendarlist.py

def CalendareventS(ServerTOKEN,AccountId,CalendarId,**EventParams):
    #Creating a request URL
    apiurl =  'https://apis.worksmobile.com/r/'+ APIID + '/calendar/v1/' + urllib.parse.quote(AccountId) + '/calendars/'+CalendarId+'/events'
    
    header = {
        'consumerKey': SERVER_CKEY,
        'Authorization': 'Bearer ' + ServerTOKEN,
        'Content-Type': 'application/json'
    }
    #Pass EventParams as appointment information
    r = requests.post(apiurl, headers = header, json = EventParams)
        return r

Appointment parameters are specified in ical format. Refer to here for how to write.

You must register the appointments one by one. I think the ics file exported from the calendar app contains multiple appointments (VEVENTs), but be aware that if you try to import it as it is, an error will occur. This is how you register your appointments in the calendar you created first.

python

f=open('demo.ics')
eventdata=f.read()
f.close()
event=CalendareventS(SERVER_TOKEN,'demo@exampletenant',Cal_ID,ical=eventdata)

There is a problem that it can not be registered in the personal basic calendar and it is only in one direction because there is no reference, but it seems that it can be conveniently used for pouring schedules from other systems.
