Get Google Calendar reminders in Zulip! This is a great way to see
your reminders directly in your Zulip feed.

1.  {!download-python-bindings.md!}

    This bot should be set up on a trusted machine, because your API
    key is visible to local users through the command line or config
    file.

1.  Next, follow the instructions for **Step 1** at
    [this link](https://developers.google.com/google-apps/calendar/quickstart/python)
    to get a `client_secret` file. Save this file as `client_secret.json`
    to your `~/` directory.

1.  Next, install the latest Google API Client for Python by following the
    instructions on the
    [Google website](https://developers.google.com/api-client-library/python/start/installation).

1.  In Zulip, go to your click on the cog in the top right corner, and
    then clicking on **Personal settings**.

1.  Click on the tab that’s labeled **Account & privacy** and click on
    **Show/change your API key**. Enter your password if prompted, and
    download the `zuliprc` file. Save this file as `.zuliprc` to your `~/`
    directory.

1.  Run the `get-google-credentials` with this command:

        python /usr/local/share/zulip/integrations/google/get-google-credentials

1.  It should open up a browser and ask you for certain permissions. Give
    Zulip access, and move on to the next step. If it doesn’t open a
    browser, follow the instructions in the terminal window.

1.  Now, all that’s left to do is to run the `gcal-bot` script, in the
    same directory as the `get-google-credentials` script, with the
    necessary parameters:

        python /usr/local/share/zulip/integrations/google/gcal-bot --user foo@zulip.com

    The `--user` flag specifies the user to send the reminder to.

1.  Don’t close the terminal window with the bot running (you can use
    `screen` if needed). You will only get reminders if the bot is still
    running.

## Supported parameters

There are two optional flags that you can specify when running this
script:

* `--calendar`: This flag specifies the calendar to watch from the
  user’s Google account. By default, this flag is set to a user’s
  primary or default calendar. To specify a calendar, you need the
  calendar ID which can be obtained by going to Google Calendar and
  clicking on the wedge next to the calendar’s name. Click on settings
  in **Calendar settings** in the drop down, and look for the **Calendar
  Address** section. Copy the **Calendar ID** from the right side of the
  page and use that as the value for this flag.

* `--interval`: This flag specifies the interval of time - in
  minutes - between receiving the reminder, and the actual event. For
  example, an interval of 30 minutes would mean that you would receive a
  reminder for an event 30 minutes before it is scheduled to occur.
