4. Select **GOOGLE_CALENDAR******as the **Provider Type Template.**
5. Accept the default **Custom Header**:

```plaintext
Content-Type: application/json; charset=utf-8
```
6. Leave the **Data Payload** blank.
7. Set the **Target URL and Path**to [https://www.googleapis.com/calendar/v3/calendars/primary/events/quickAdd?text=Meeting%20now%20for%2030%20minutes](https://www.googleapis.com/calendar/v3/calendars/primary/events/quickAdd?text=Meeting%20now%20for%2030%20minutes)

### Configuring an 8450 Button to Create a Google Calendar Schedule

You can configure a button on the Algo 8450 to create a Google Calendar schedule.

![](https://cdn.document360.io/f6f5e62d-d280-487f-9da7-5926ffd53b5f/Images/Documentation/image(934).png)

**To configure an 8450 button to create a Google Calendar meeting:**

1. Create a button on an 8450 screen.
2. Set the **Button Status** to **Enabled.**
3. Configure the following:
  - **Text**: Enter the button display text.
  - **Action**: Set to **Send API Request**.
  - **Number of API Requests**: Set to **1**.
  - **Request 1 - Command**: Set to **Other**.
  - **Request 1 - Method**: Set to **POST**.
  - **Request 1 - Custom Path**: Set to `calendar/v3/calendars/primary/events/quickAdd?text=Meeting%20now%20for%2030%20minutes`

This creates a test meeting starting from now that lasts 20 minutes.
  - **Request 1 - Targets**: Set to `www.googleapis.com`
  - **Request 1 - OAuth Profile**: Select your Google Calendar profile.
  - **Request 1 - Headers**: Set to **Custom Headers**.
  - **Request 1 - Custom Headers**: Set to `Content-Type: application/json; charset=utf-8`
  - **Request 1 - Data Payload**: None
4. Select**Save.**

Press the button and verify that the schedule is created in your Google Calendar.

#### Troubleshooting

**I get a 502 error when I run the OAuth Test**

You may be logged out of the device’s web interface. Log in again and retry.

**After I run the “Start Authorization” again, my OAuth Test fails**

Each time you run **Start Authorization** again, select **Update Profile** to save the new credentials before running the test.

**My OAuth profile stops working**

An OAuth profile can stop working if the OAuth provider rejects or invalidates the access or refresh token. Refer to the OAuth provider’s documentation for more information. If this occurs, the OAuth profile must be reauthorized.
