# Add integrations

> Send every Velocity booking to the customer's Google Calendar.

export const AiPrompt = ({children}) => {
  return <CodeBlock className="relative block font-sans whitespace-pre-wrap break-words">
      <div className="pr-7">
        {children}
      </div>
    </CodeBlock>;
};

By the end, every Velocity reservation will land on the customer's Google Calendar with the pickup and return times already filled in.

Integrations let Velocity talk to other tools. You could send each booking to the customer's calendar, email a coordinator when a high-value rental is reserved, or pull weather into the trip-planning page. Pick one for now — Google Calendar gives every customer a clear, verifiable artifact ("the rental is on my calendar"), and you can check it on your own calendar during testing.

## Tell Agent to add the calendar integration

Replit ships a built-in **Google Workspace connector** that covers Google Calendar. Agent signs in to Google with a single click — there are no API projects to create, no OAuth credentials to copy, and no secrets to paste.

<AiPrompt>
  After a Velocity customer confirms a reservation, add the rental to their Google Calendar.<br />
  Use Replit's Google Workspace connector for Google Calendar — don't ask me for any OAuth credentials.<br />
  The event title should be "Velocity rental: \[car make and model]".<br />
  The event should span pickup time to return time and include the pickup address and the reservation reference in the description.<br />
  Update the calendar event automatically if the customer changes the dates or cancels the reservation.<br />
  Add a clear message in Velocity if the calendar add fails, so the reservation still confirms.
</AiPrompt>

Agent will provision the Google Workspace connector, open a single Connect dialog in the workspace, and after you sign in with the Google account that owns the calendar, wire Velocity to add an event every time a reservation is confirmed.

<Note>
  Connectors are a Core, Pro, or Enterprise feature. On the free plan, ask Agent to use a Google OAuth project instead — you'll need to create a Google Cloud project, enable the Calendar API, and paste the resulting credentials into your app's Secrets pane.
</Note>

## Test it end-to-end

1. Open your own Google Calendar in a new tab.
2. Sign in to Velocity in Preview.
3. Reserve a car for next Saturday-Sunday and confirm the booking.
4. Switch to your Google Calendar tab. A new "Velocity rental: \[car]" event should appear on Saturday-Sunday with the pickup address in the description.
5. Change the reservation in Velocity to Sunday-Monday. The calendar event should move automatically.
6. Cancel the reservation. The calendar event should disappear.
7. As a second test, open **Integrations** in the workspace and disconnect Google Workspace, then try to book. Velocity should still confirm the reservation and show a clear message like "Couldn't add to your calendar — your reservation is confirmed." Reconnect the connector once the test passes.

If the reservation confirms but no event appears, paste the exact error back to Agent:

<AiPrompt>
  The integration failed with this error: \[paste the error from Velocity or the Replit logs].<br />
  Tell me the likely cause and fix the smallest issue.<br />
  Make sure reserving a car still works in Velocity even if Google Calendar is unreachable.
</AiPrompt>

## Publish and try it from the public URL

Once the calendar integration works in Preview:

1. Publish Velocity again from the Agent chat.
2. Open the public URL and book a car from a real customer's perspective.
3. Confirm the event appears on the calendar of the account that booked.
4. Update and cancel a booking from the public URL and confirm the calendar event follows.

Customers now leave Velocity with the rental already on their calendar. The reservation isn't just a confirmation email — it's an event they can't forget.

## Need further help?

* **No event appears in Google Calendar:** open **Integrations** in the workspace, confirm the Google Workspace connector shows Connected, and that the Calendar scope is granted.
* **The connector shows Connected but events still don't land:** ask Agent to log the calendar payload it sends, then fix the field mapping.
* **Date or address fields land in the wrong place on the event:** ask Agent to log the event shape it sends, then fix the field mapping.
* **You want a different integration:** swap "Google Calendar" for any other connector — Slack notifications for the team, HubSpot to log customers as CRM contacts, Airtable to track bookings in a shared base. Agent handles each the same way through the Integrations pane.
