πŸ“– About This Skill

name: posthog description: > Interact with PostHog analytics via its REST API. Capture events, evaluate feature flags, query data with HogQL, manage persons, insights, dashboards, experiments, surveys, cohorts, annotations, and session recordings. Use when the user mentions "PostHog", "PostHog API", "PostHog events", "PostHog feature flags", "PostHog insights", "PostHog query", "HogQL", "PostHog persons", "PostHog dashboards", "PostHog experiments", "PostHog surveys", "PostHog cohorts", "PostHog recordings", "capture events PostHog", or "PostHog analytics". metadata: env: - POSTHOG_API_KEY (required): "Personal API key β€” create at https://us.posthog.com/settings/user-api-keys" - POSTHOG_PROJECT_ID (required): "Project ID β€” find at https://us.posthog.com/settings/project#variables" - POSTHOG_PROJECT_API_KEY: "Project API key (for public capture/flags endpoints)" - POSTHOG_HOST: "API host (default: https://us.posthog.com)" - POSTHOG_INGEST_HOST: "Ingest host (default: https://us.i.posthog.com)"

PostHog API Skill

Interact with PostHog via its REST API. Two types of endpoints:

  • Public (POST-only, project API key): capture events, evaluate flags β€” no rate limits
  • Private (personal API key): query, CRUD for all resources β€” rate limited

    • Setup

    1. Get personal API key: https://us.posthog.com/settings/user-api-keys 2. Get project ID: https://us.posthog.com/settings/project#variables 3. Set env vars: 

       export POSTHOG_API_KEY="phx_..."
   export POSTHOG_PROJECT_ID="12345"
   export POSTHOG_PROJECT_API_KEY="phc_..."  # optional, for capture/flags
   # For EU Cloud:
   # export POSTHOG_HOST="https://eu.posthog.com"
   # export POSTHOG_INGEST_HOST="https://eu.i.posthog.com"
    4. Verify: bash scripts/posthog.sh whoami

    Helper Script

    scripts/posthog.sh wraps common operations. Run bash scripts/posthog.sh help for full usage.

    Examples

    # Capture an event
bash scripts/posthog.sh capture "signup" "user_123" '{"plan":"pro"}'
    Evaluate feature flags
    
bash scripts/posthog.sh evaluate-flags "user_123"
    HogQL query β€” top events last 7 days
    
bash scripts/posthog.sh query "SELECT event, count() FROM events WHERE timestamp >= now() - INTERVAL 7 DAY GROUP BY event ORDER BY count() DESC LIMIT 20"
    List persons
    
bash scripts/posthog.sh list-persons 10 | jq '.results[] | {name, distinct_ids}'
    List feature flags
    
bash scripts/posthog.sh list-flags | jq '.results[] | {id, key, active}'
    Create a feature flag
    
echo '{"key":"new-dashboard","name":"New Dashboard","active":true,"filters":{"groups":[{"rollout_percentage":50}]}}' | \
  bash scripts/posthog.sh create-flag
    List dashboards
    
bash scripts/posthog.sh list-dashboards | jq '.results[] | {id, name}'

    Key Concepts

    Two API types

  • Public endpoints (/i/v0/e/, /batch/, /flags): Use project API key in body. No auth header. No rate limits.
  • Private endpoints (/api/projects/:project_id/...): Use personal API key via Authorization: Bearer. Rate limited.

    • HogQL Queries

    The query endpoint (POST /api/projects/:project_id/query/) is the most powerful way to extract data. Uses SQL-like HogQL syntax against tables: events, persons, sessions, groups, plus data warehouse tables.

    Always include time ranges and LIMIT. Use timestamp-based pagination for large exports.

    Rate Limits (private endpoints)

    | Type | Limit | |------|-------| | Analytics (insights, persons, recordings) | 240/min, 1200/hr | | Query endpoint | 2400/hr | | Feature flag local evaluation | 600/min | | Other CRUD | 480/min, 4800/hr |

    Limits apply per organization. On 429: back off and retry.

    Domains

    | Cloud | Public | Private | |-------|--------|---------| | US | us.i.posthog.com | us.posthog.com | | EU | eu.i.posthog.com | eu.posthog.com |

    Events API (deprecated)

    The /api/projects/:project_id/events/ endpoint is deprecated. Use HogQL queries or batch exports instead.

    Direct curl

    # Private endpoint
curl -H "Authorization: Bearer $POSTHOG_API_KEY" \
  "$POSTHOG_HOST/api/projects/$POSTHOG_PROJECT_ID/feature_flags/"
    HogQL query
    
curl -H "Authorization: Bearer $POSTHOG_API_KEY" \
  -H "Content-Type: application/json" \
  -X POST -d '{"query":{"kind":"HogQLQuery","query":"SELECT count() FROM events WHERE timestamp >= now() - INTERVAL 1 DAY"}}' \
  "$POSTHOG_HOST/api/projects/$POSTHOG_PROJECT_ID/query/"
    Capture event (public)
    
curl -H "Content-Type: application/json" \
  -X POST -d '{"api_key":"'$POSTHOG_PROJECT_API_KEY'","event":"test","distinct_id":"u1"}' \
  "$POSTHOG_INGEST_HOST/i/v0/e/"

    Full API Reference

    See references/api-endpoints.md for complete endpoint listing with parameters, body schemas, scopes, and response formats.

    Sections: Public Endpoints (Capture, Batch, Flags), Private Endpoints (Persons, Feature Flags, Insights, Dashboards, Annotations, Cohorts, Experiments, Surveys, Actions, Session Recordings, Users, Definitions), Query API (HogQL).

    πŸ’‘ Examples

    # Capture an event
bash scripts/posthog.sh capture "signup" "user_123" '{"plan":"pro"}'
    Evaluate feature flags
    
bash scripts/posthog.sh evaluate-flags "user_123"
    HogQL query β€” top events last 7 days
    
bash scripts/posthog.sh query "SELECT event, count() FROM events WHERE timestamp >= now() - INTERVAL 7 DAY GROUP BY event ORDER BY count() DESC LIMIT 20"
    List persons
    
bash scripts/posthog.sh list-persons 10 | jq '.results[] | {name, distinct_ids}'
    List feature flags
    
bash scripts/posthog.sh list-flags | jq '.results[] | {id, key, active}'
    Create a feature flag
    
echo '{"key":"new-dashboard","name":"New Dashboard","active":true,"filters":{"groups":[{"rollout_percentage":50}]}}' | \
  bash scripts/posthog.sh create-flag
    List dashboards
    
bash scripts/posthog.sh list-dashboards | jq '.results[] | {id, name}'

    βš™οΈ Configuration

    1. Get personal API key: https://us.posthog.com/settings/user-api-keys 2. Get project ID: https://us.posthog.com/settings/project#variables 3. Set env vars: 

       export POSTHOG_API_KEY="phx_..."
   export POSTHOG_PROJECT_ID="12345"
   export POSTHOG_PROJECT_API_KEY="phc_..."  # optional, for capture/flags
   # For EU Cloud:
   # export POSTHOG_HOST="https://eu.posthog.com"
   # export POSTHOG_INGEST_HOST="https://eu.i.posthog.com"
