What you'll build​

Build a Google Calendar integration that creates a new calendar event using OAuth2 credentials stored as configurable variables. The integration runs as an Automation entry point and connects to Google Calendar via the ballerinax/googleapis.calendar connector.

Operations used:

  • Create Event : Creates a new event in a specified Google Calendar using an InputEvent record with start time, end time, and summary.

Architecture​

Prerequisites​

  • A Google Cloud project with OAuth2 credentials: Client ID, Client Secret, and Refresh Token.

Setting up the Google calendar integration​

New to WSO2 Integrator? Follow the Create a New Integration guide to set up your integration first, then return here to add the connector.

Adding the Google calendar connector​

Select Add Connection in the Connections section of the left sidebar (or select the + button next to Connections) to open the Add Connection palette.

Google Calendar connector palette open with search field before any selection

Step 1: Search for and select the Google calendar connector​

Search for "calendar" in the palette and select the ballerinax/googleapis.calendar connector card to open the connection configuration form.

Configuring the Google calendar connection​

Step 2: Fill in connection parameters​

Bind each OAuth2 field in the Configure Calendar form to a configurable variable. Select the record icon next to the Config field to open the Record Configuration modal, then map the following parameters:

  • refreshUrl : The OAuth2 token endpoint URL, bound to a configurable variable
  • refreshToken : The OAuth2 refresh token, bound to a configurable variable
  • clientId : The OAuth2 client ID, bound to a configurable variable
  • clientSecret : The OAuth2 client secret, bound to a configurable variable

Set the Connection Name to calendarClient.

Step 3: Save the connection​

Select Save. The calendarClient connection node appears in the Connections panel.

Step 4: Set actual values for your configurables​

In the left panel, select Configurations. Set a value for each configurable listed below:

  • calendarRefreshUrl (string) : The OAuth2 token endpoint; use https://oauth2.googleapis.com/token
  • calendarRefreshToken (string) : Your OAuth2 refresh token obtained from Google Cloud Console
  • calendarClientId (string) : Your OAuth2 client ID from Google Cloud Console
  • calendarClientSecret (string) : Your OAuth2 client secret from Google Cloud Console

Configuring the Google calendar createEvent operation​

Step 5: Add an automation entry point​

In the left sidebar under Entry Points, select + to add a new entry point. Select Automation and name it main. The Automation flow canvas opens, showing a Start node and an Error Handler node.

Step 6: Select and configure the createEvent operation​

Expand the calendarClient connection node on the canvas to view available operations.

Select Create Event to open the operation configuration form, then fill in the following fields:

  • calendarId : The calendar identifier; use "primary" for the user's default calendar
  • event : A complete InputEvent record with summary, start, and end fields (each Time record requires dateTime and timeZone)
  • result variable : Leave the default name calendarEvent

Select Save. The calendar : createEvent node is added to the Automation flow canvas, connected to the calendarClient connection.
