   • multivariate-test (a multivariate flag)
   • simple-test (a simple boolean flag)
   • multivariate-simple-test (a multivariate flag)
   • my_secret_flag_value (a remote config flag with string payload)
   • my_secret_flag_json_object_value (a remote config flag with JSON object payload)
   • my_secret_flag_json_array_value (a remote config flag with JSON array payload)

3. Set your PostHog API keys as environment variables:

   • POSTHOG_PROJECT_API_KEY: Your project API key (starts with phc_...)
   • POSTHOG_PERSONAL_API_KEY: Your personal API key (starts with phx_...)
