Get the latest schedule from Google Calendar and notify it on LINE every morning

At my home, we have introduced a slightly convenient one that notifies LINE of the schedule from the day to the day after tomorrow every morning: rolling_eyes:

Overview

--Get static data from S3 --Get the schedule until the day after tomorrow with Google Calendar API --Notify the talk room set by LINE Notify API

material

--AWS Lambda ... one --Google Calendar ... one or more --GCP service account ... one or more --LINE Notify access token ... one or more

(as you like) --AWS S3 ... one

How to make

A. GCP console

1. Enable the Google Calendar API.
2. Create a service account. ... If you only want to share with a limited number of users as a requirement, it's best to use a service account.
3. Add the service account created in 2. to "Share with specific users" to the calendar you want to notify.

B. LINE Notify

1. Issue an access token for the room you want to notify.

C. AWS Lambda

1. Get the latest appointments with the Google Calendar API using the key for the Google service account created in A.
2. Notify the room using the LINE Notify API with the access token created in B.
3. (Supplement) Is it relatively convenient to put static data used for notification in S3 so that it can be referred to by IAM?

that's all! It was a little convenient to be able to do it quickly ~
