# OPA Google Calendar Integration

Companion code for the [Styra blog](https://blog.styra.com/blog/the-power-of-data-calendar-based-policy-enforcement) on integrating OPA with the Google Calendar API as a datasource.

## Extract events from Google Calendar

* Create a GCP service account. You do not need to change any defaults.

* In your service account settings, click "Keys" and "New key". Download the credentials file.

* Export the service account email as an env variable: `export [email protected]`

* Export the private key as an env variable: `export SIGNING_KEY=$(cat credentials.json | jq -r .private_key)`

* In Google Calendar, click the calendar you want to use and choose "Settings and sharing".

* From the menu to the left, click "Share with specific people". Add the service account e-mail address.

* From the menu to the left, click "Integrate calendar". Copy the Calendar ID value.

* Export the calendar ID: `export CALENDAR_ID=`

* Extract events and save to file: `opa eval --format raw --data events.rego data.google.calendar > calendar.json`
