## Testing vs. Production

Under the [API](https://app.heypoplar.com/integrations/api_keys) section of your **Integrations** page you will find two API Keys: <mark style="color:$success;">Production</mark> and <mark style="color:$warning;">Test</mark>.

<figure><img src="/files/qVJaSl8sOf2fRn1VpxmR" alt=""><figcaption></figcaption></figure>

When setting up your Poplar integration, it is **important** to always use your **Test** access token when configuring your authentication headers. This will allow you to send mailing data to a Poplar campaign without actually mailing pieces or being charged. From your Campaign's Overview, you should be able to see requests populating towards the bottom of the page. You can click into each request to see the mailing data and (optionally) merge tag data.

Once you've confirmed the connection is successfully, and all the necessary data is flowing correctly, you can swap your **Production** token in where your Test one is to **go live** and start mailing.
