README

This WordPress plugin just provide you with the API Client. It doesn't do anything without coding in your Theme.

For documentation reads: https://github.com/google/google-api-php-client

Requirement

• PHP version 5.6 or higher
• WordPress version 4.9.6

Local Testing

You need SSL to make the API works.

If you're in Windows, you can add certificate to your WAMP or XAMPP installation by following these steps:

1. Download latest certificate from https://curl.haxx.se/docs/caextract.html

2. Put it in PHP folder like C:\xampp\php\extras\ssl\ or C:\wamp64\bin\php\php7.0.0\extras\ssl

3. In php.ini file, uncomment "curl.cainfo" and put in the path to your SSL file like curl.cainfo = "C:\xampp\php\extras\ssl\cacert-2018-06-02.pem".

4. Done your API should now work even without changing your Virtual Host to HTTPS.

Displaying Own Calendar

You can skip the OAuth process if only for displaying own calendar. Follow these steps:

1. I assume you have created API Console with permission to get Calendar API. If not do it here https://console.developers.google.com

2. Go to Menu > IAM & Admin > Service Accounts. Create a new account, name it anything, and set the role to Project > Viewer. Tick "Furnish new Private key".

3. You will automatically download a JSON file. Keep this safe because you can't redownload it.

4. Open your Calendar and grant permission to view for the Service Account's email. If you want to see the Color, you need to grant Read & Write access.

5. Setup is done. You can find sample code here: https://gist.github.com/hrsetyono/5d8623bd8f28da3e282441ce1314f022
