Vellum
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 Vellum to PostHog to sync your data into the PostHog data warehouse for analysis and modeling.
Enter your Vellum API key to sync your Vellum deployments, documents, and execution history into the PostHog Data warehouse.
You can create an API key in your Vellum workspace settings. Vellum API keys are environment-scoped (Development / Staging / Production), so one key syncs one environment.
