Anvil
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 Anvil to PostHog to sync your data into the PostHog data warehouse for analysis and modeling.
Sync metadata about your Anvil documents into the PostHog Data warehouse: organizations, PDF templates (casts), workflows (welds), workflow submissions, and e-signature packets with their signer status.
Create an API key in your Anvil organization settings, under API settings. Development keys are rate limited to 4 requests per second, so large accounts sync faster with a production key.
Only metadata is synced. Filled PDFs, signed documents, and submission form data never leave Anvil.
