Avalara AvaTax
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 Avalara AvaTax to PostHog to sync your data into the PostHog data warehouse for analysis and modeling.
Connect your Avalara AvaTax account to pull tax transactions, companies, nexus, customers and exemption certificates into the PostHog Data warehouse.
Use your AvaTax account ID and a license key (found under Settings > License and API Keys). Generating a new license key immediately revokes the previous one. Sandbox and production credentials only work against their matching environment, so pick the one your account was created in.
