# Opensend

Opensend allows you to track customers on your site who did not supply any identifying information. It does this through various back-office lookups.

You can connect this data to your survey responses retroactively. This allows you to identify users who took your survey anonymously and contact or merge their response data with an underlying profile.

To set this up, try the following:

1. **Install the Opensend tracking pixel:** [**https://help.opensend.com/how-do-i-install-the-opensend-pixel-on-my-website**](https://help.opensend.com/how-do-i-install-the-opensend-pixel-on-my-website)
2. Create an API key in Zigpoll.
   1. Go to the Zigpoll dashboard
   2. Click Integrations -> API Keys
   3. Create an API Key and copy it for later. Label it something easy to remember like **Opensend Key**
3. Log into Opensend and Create a new Destination
4. Select Custom Webhook.
5. Enter **<https://v1.zigpoll.com/opensend>** where it says Webhook URL
6. Select API Key as the authentication method
7. Enter a header called **Authorization** with value equal to your Zigpoll API key from step 2
8. Select all fields from the Fields selector and click Next.

9. Click Create Destination

That's it. Now whenever you receive identifying information it will be automatically synced with your Zigpoll survey respondents. This will de-anonymize them and allow you to contact them in the future or build rich profiles.
