Google Analytics 4 (GA4) shows how many people visit your BCL homepage and forms, and which of them paid. You connect it once for your whole account: a **Measurement ID** for visits and a **Measurement Protocol API secret** for purchases.

These are the events your GA4 property receives from BCL:

| Event | When | Sent from |
| --- | --- | --- |
| **page_view** | A customer opens your homepage, a form or a receipt. | Browser |
| **begin_checkout** | The customer clicks the pay button. On a lead form this is **generate_lead**. | Browser |
| **purchase** | The payment succeeds. Includes the order number, amount and form name. | BCL's server |

The purchase is sent from BCL's server, so ad blockers cannot stop it. It is sent only for successful payments; pending COD and bank transfer orders are sent when you mark them paid.

## Get your Measurement ID and API secret

You need both values from Google Analytics:

1. In [Google Analytics](https://analytics.google.com/), go to **Admin** → **Data streams** and click your web stream.
2. Copy the **Measurement ID**. It starts with G-.
3. On the same page, open **Measurement Protocol API secrets**, click **Create**, give it a name (for example BCL) and copy the **Secret value**.

## Connect Google Analytics to BCL

The setting is on the Integrations page and covers every form in your account.

1. Go to **Platform Setup** → **Integrations**.

2. Open the **Google** tab.

3. Under **Google Analytics**, paste your ID into **Measurement ID** and your secret into **Measurement Protocol API secrets**.

4. Click **Save Google Analytics Configuration**.

> **Note**
> The Google tab also holds **Google Sheets Integration**. It is separate from Google Analytics and is used by automations.

## Tips

A few things make your GA4 reports more useful:

- **Check purchases in BCL.** Go to **Tools** → **Marketing Logs** and open the **Google Analytics** tab. Each row is a purchase BCL sent to your property. See [Marketing Pixel Logs](/marketing-pixel-logs/).
- **Mark purchase as a key event.** In Google Analytics, go to **Admin** → **Events** and mark **purchase** as a key event, so it shows as a conversion in your reports.
- **Running Google Ads too?** GA4 does not replace the form's Google Ads tag. Add that on each form: see [Track Google Ads conversions on a form](/google-ads-conversion/).

## Common issues

### Do I add Google Analytics to every form?

No. Google Analytics is set once for your account under Platform Setup → Integrations → Google, and it covers your homepage and all your forms.

### I see visits in Google Analytics but no purchases. Why?

Purchases are sent from BCL's server, which needs the Measurement Protocol API secrets value. Add it next to your Measurement ID and save.

### Why does BCL say my Measurement ID is not valid?

It must be a Google Analytics 4 ID: G- followed by 10 letters and numbers, for example G-AB12CD34EF. Old Universal Analytics IDs (UA-) do not work.
