# Setup Messaging & Calendar sync

Twenty offers integrations with Gmail and Google Calendar.

## For Gmail and Google Calendar

### Create a project in Google Cloud

You will need to create a project in Google Cloud and get the credentials.

Then you can set the following environment variables:

- `MESSAGING_PROVIDER_GMAIL_ENABLED=true`
- `CALENDAR_PROVIDER_GOOGLE_ENABLED=true`
- `AUTH_GOOGLE_CLIENT_ID=<client-id>`
- `AUTH_GOOGLE_CLIENT_SECRET=<client-secret>`
- `AUTH_GOOGLE_CALLBACK_URL=https://<your-domain>/auth/google/redirect` if you want to use Google SSO
- `AUTH_GOOGLE_APIS_CALLBACK_URL=https://<your-domain>/auth/google-apis/get-access-token`

### Enable APIs

On Google Cloud Console, go to [APIs & Services](https://console.cloud.google.com/apis/library/) and enable the following APIs:

- [Gmail API](https://console.cloud.google.com/apis/library/gmail.googleapis.com)
- [Google Calendar API](https://console.cloud.google.com/apis/library/calendar-json.googleapis.com)
- [People API](https://console.cloud.google.com/apis/library/people.googleapis.com)

### Authorized redirect URIs

Under [Credentials](https://console.cloud.google.com/apis/credentials), in OAuth 2.0 Client IDs, you need to add the following redirect URIs to your project:

- `https://<your-domain>/auth/google/redirect` if you want to use Google SSO
- `https://<your-domain>/auth/google-apis/get-access-token`

### If your app is in test mode

If your app is in test mode, you will need to add test users to your project.

Under [OAuth consent screen](https://console.cloud.google.com/apis/credentials/consent), add your test users to the "Test users" section.

### Start the cron jobs

Register the following recurring jobs:
```
# from your worker container
yarn command:prod cron:messaging:messages-import
yarn command:prod cron:messaging:message-list-fetch
yarn command:prod cron:calendar:calendar-event-list-fetch
yarn command:prod cron:messaging:ongoing-stale
yarn command:prod cron:calendar:ongoing-stale
```
