Connect Tailscale to PostHog to sync your data into the PostHog data warehouse for analysis and modeling.

Sync your Tailscale devices, users, keys, and configuration audit logs into the PostHog Data warehouse.

An OAuth client is the recommended credential for recurring syncs — API access tokens expire after at most 90 days. Create one in the Tailscale admin console under Settings > OAuth clients, with read scopes for the tables you want to sync (for example devices:core:read, users:read, auth_keys:read, and logs:configuration:read).

Alternatively, generate an API access token under Settings > Keys. Leave the tailnet field blank to use the credential's default tailnet.

Configuration

Option	Description
