Testing vs. Production

Under the API section of your Integrations page you will find two API Keys: Production and Test.

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.
