API: Test & Production Tokens
From the API tab under Integrations, you can generate and name both Production and Test API keys. These keys are used to authenticate each request sent to Poplar. To access Poplar APIs you'll need to use either a Test or Production Access Token.
Test Access Token
Your test access token allows you to send test requests to the Mailing API without actually sending anything, and without being charged. This is the best way to test the success of platform integrations and preview custom merge tags to ensure the necessary data is coming through and populating correctly. Successful Tests can be seen from your campaign's History tab:
If you click into a Test mailer labeled In Production, you'll see an image preview of the mailer with the recipient details and merge tag values applied for dynamic creative. If a mailer has a suppressed, insufficient funds, address invalid, or failed (address enrichment not enabled) status a preview ill not be generated.
Scroll to the bottom of the page to see the Request Details. This shows the data that has been sent to Poplar from your third party platform, and is the best way to ensure all the necessary data is coming through (email, customer_id, custom merge tags, etc.) and mapping properly:
Additionally, the Merge Tags section can be used to confirm successful mapping. If no value is passed or if the is a mapping error, the set default value will be used:
Production Access Token
Once you've confirmed the connection is successful and customer data is coming through to Poplar as desired, use your Production Access Token in place of your Test token, save all updates accordingly to go live!
