Connecting it

• You provide: Personal API key + Project API key + host
• Where to get it: Reads use a PERSONAL API key: PostHog → Settings → Personal API keys → create a key (scope it insight:read / query:read for least privilege). Capture uses a separate PROJECT API key: Project Settings → Project API Key. Pick the matching host — US Cloud https://us.posthog.com, EU Cloud https://eu.posthog.com, or your self-hosted domain — and your numeric project id.
• Permissions/scopes: insight:read, query:read

Account setup

• Account needed: A PostHog account (Cloud or self-hosted) with a project.
• App registration: No app review. Mint a Personal API key (Settings → Personal API keys) for reads and grab the Project API Key (Project Settings) for capture.
• Verification required: None — access is governed by the personal API key's scopes and project membership.
• Testing: PostHog Cloud free tier (1M events/mo) on https://us.posthog.com.
