## Overview
This topic explains how to create and test a Twilio Segment destination for Data Export.
## Prerequisites
There are two prerequisites to configure the Twilio Segment integration:
* You must add the LaunchDarkly Source in Twilio Segment
* You must find the **Write Key** for your Twilio Segment accountFirst, add the LaunchDarkly Source in Twilio Segment. To add the source, [read Twilio's documentation](https://www.twilio.com/docs/segment/connections/sources/catalog/cloud-apps/launchdarkly). Next, configure the Twilio Segment integration in LaunchDarkly. To do this, you need the **Write Key** from your Twilio Segment account. To find the write key:
1. Log into Twilio Segment and navigate to your project.
2. Navigate to **Sources** and select your LaunchDarkly source.
3. Select **API Keys** on the Source integration's menu bar.
4. Copy the **Write Key** as shown in the text box:
## Create a Twilio Segment destination in Launch
DarklyTo create the Twilio Segment destination:
1. In LaunchDarkly, click the **gear** icon in the left sidenav to view Organization settings.
2. Click **Integrations** and find "Twilio Segment."
3. Click **Add integration.** The "Create a destination" panel appears.
4. (Optional) Give your integration a human-readable **Name**.
5. Choose an **Environment** for this integration to apply to.
6. Enter the Twilio Segment **Write key**.
7. Click **Save destination**. The new integration appears in the list of integrations.
## Test a Twilio Segment destination
After you save the destination, send a test event to confirm that the destination is configured properly.
To send a test event:
1. Navigate to the **Integrations** page and find "Twilio Segment."
2. Click the **down arrow** next to "Add integration" to display a list of existing destinations.
3. Click the **pencil** icon next to the destination you want to test. The "Edit destination" panel appears.
4. In the "Send a test event" section, click **Send event**.
5. Verify the event appears in the Twilio Segment **Debugger**.
## Example events
These example events display the structure of the events LaunchDarkly sends to Twilio Segment.
LaunchDarkly sends events in the following formats:

## Enable Data Export for flags and environments
After you create a Data Export destination, you must start sending flag or environment event data to it. You can enable Data Export for individual flags, or for all the flags in an environment.
To learn more, read [Export event data for flags and environments](/integrations/data-export#export-event-data-for-flags-and-environments).
## Delete a Twilio Segment destination
You can delete a Data Export destination from the **Integrations** screen.
To delete a destination:
1. Navigate to the **Integrations** page and find "Segment."
2. Click into the "Segment" section to display a list of destinations.
3. Click the **pencil** icon next to the destination you wish to delete. The "Edit destination" panel appears.
4. Click **Delete destination**.
