# Set up Google Calenday Sync- 1 way

## Here is how you can set up a sync with your Google Calendar for a 1 way sync from Zapfloor

**Step 1**. Service account with a JSON key

The key is what Zapfloor authenticates with. Without it nothing works.

**In Google Cloud**, all in one project:

1. **Menu › APIs & Services › Library › Google Workspace** → **Calendar API** → Enable
2. Same for **Admin SDK API**
3. **Menu › IAM & Admin › Service Accounts › Create service account** → name → Done (no IAM roles needed; access is granted in step 6)
4. Open the service account → **Keys** tab → **Add key › Create new key › JSON › Create**

The JSON downloads immediately and is the only copy — store it safely. Also note the service account's **email address**.

**In Zapfloor**, go to **Integrations › Connections › Create connection** and pick type *Google Calendar*. That form has two fields: a name and **Authentication file** — upload the JSON there.

**Step 2**. Domain-wide delegation

**In Google Admin:** **Security › Access and data control › API controls › Manage Domain Wide Delegation › Add new**

| Field | Value |
| --- | --- |
| Client ID | the service account's **Client ID** (service account → *Show advanced settings*) |
| OAuth scopes | https://www.googleapis.com/auth/calendar |

 

 

**Step 3**. Create resources

Create the meeting room in Google Admin under **Directory › Buildings and resources › Resources**, with category *Conference room*.

Note the **resource email address** Google generates (something like c\_188…@resource.calendar.google.com).

 The operator needs to create each meeting room as a resource.

**Step 4.** Share the resource with the service account

This is the step most often skipped, and without it you get notFound: Not Found. Google returns a 404 rather than a 403 for a calendar you are not allowed to see — so it looks as if the room does not exist.

Per room, through the interface

1. Open **Google Calendar** with your admin account
2. If the room is not under **My calendars**: **Other calendars › Subscribe to calendar**, add the resource email
3. Hover the room → **More › Settings and sharing**
4. Under **Share with specific people** → **Add people**
5. Enter the service account's email → **Make changes to events** → **Send**

**Step 5.** Enable the workflows in Zapfloor

The outbound sync runs on workflow actions, not on a checkbox. Enable the ones you need per account:

| Action | Does |
| --- | --- |
| google\_calendar\_event\_create | Reservation created → event in the room calendar |
| google\_calendar\_event\_update | Reservation changed → event updated |
| google\_calendar\_event\_remove | Reservation deleted → event deleted |

S**tep 6.** Enter the resource email in Zapfloor

Fill in the resource email from Step 3 on the meeting room. This is the switch that activates everything.
