Instafloss verifies each new person in Ortto within minutes of joining. Ortto does not let apps register webhooks for you, so you add a webhook in Ortto and send one activity to it. It takes about five minutes.

## Before you start

- Connect Ortto to mailfloss first. See [How to connect Ortto to mailfloss](https://docs.mailfloss.com/how-to-connect-ortto-to-mailfloss).
- Instafloss needs the Business plan or the Instafloss add-on.

## Step 1: Turn on Instafloss in mailfloss

1. In mailfloss, open your Ortto connection and go to the **Schedule** tab.
2. Turn on **Instafloss**.
3. Copy the **URL** and the **token**. mailfloss shows the token only once. If you lose it, click **Replace token** to get a new one.

## Step 2: Send new people to mailfloss from Ortto

1. In Ortto, create an audience of everyone with an email address: go to **CDP > Audiences**, filter on **Email** **has any value**, and save it.
2. Go to **CDP > Data sources > New data source** and choose **Webhook (advanced)**.
3. Paste the mailfloss URL and keep the method **POST**.
4. Under **Custom headers**, add `X-Mailfloss-Token` with the token from mailfloss. Click **Create**.
5. Go to **CDP > Activities** and open **Entered audience**.
6. Under **Data destinations**, choose **Send activity to destination**, pick the webhook you just made, and click **Save**.

The **Test** button on the webhook sends one real person from your account, so mailfloss verifies that person.

## Step 3: Check that it works

Add a test person to Ortto. Within a few minutes, the Instafloss panel in mailfloss changes from **Waiting for the first event** to the time of the last event, and the person appears in your Instafloss results.

## Turning Instafloss off

Turn off **Instafloss** in mailfloss. mailfloss stops verifying events right away. You can leave the data destination in place or set it back to **Don't send activity** in Ortto. When you turn Instafloss back on, the same URL and token work again.

## Replacing the token

Click **Replace token** in mailfloss, then paste the new token into the `X-Mailfloss-Token` header of the webhook data source in Ortto. The old token stops working at once.
