Integrations and developer access
Write keys
Create, regenerate, and revoke per-site credentials for server event ingestion.
Open Settings → API keys, select a site, and create its write key. The key authorizes POST /api/track; keep it in a server environment variable and send it as a Bearer token.
Regenerating replaces the active secret, so update the server before retiring the old deployment. Revoke a key when an integration is removed or compromised. Write keys are not MCP keys and should never be embedded in browser code.
