Poplar
Let AI connect your sources for you
Skip the manual setup — run this in your project and the wizard auto-detects your databases and APIs and connects them to PostHog.

Connect Poplar to PostHog to sync your data into the PostHog data warehouse for analysis and modeling.
Enter a production access token from the API page of your Poplar account. Test tokens can only send mailings, so they can't read data. Poplar lists active campaigns only, so creatives and mailings sync for active campaigns.
