PostHog Analytics Skill#

Automate PostHog dashboard creation, sync, update, and export via API.

Prerequisites#

Required Tools#

• curl - HTTP client (pre-installed on macOS/Linux)
• jq - JSON processor: brew install jq or apt install jq
• bash - Shell (the script is bash)

PostHog API Key#

1. Go to PostHog Settings → Personal API Keys
2. Create a new key with read/write access
3. Export it:

bash

export POSTHOG_PERSONAL_API_KEY=phx_xxx

Note: The API key determines your organization and project. The script uses @current project context (your default project).

Verify Setup#

bash

# Test your API key - should return your project info
curl -s -H "Authorization: Bearer $POSTHOG_PERSONAL_API_KEY" \
  "https://us.i.posthog.com/api/projects/@current/" | jq '{id, name}'

Expected output:

json

{
  "id": 209268,
  "name": "Default project"
}

If you get an error, check your API key is correct and has proper permissions.

Quick Start: Blog Analytics Example#

Step 1: Write Your Config#

Create blog_dashboard.json:

json

{
  "name": "Blog Analytics",
  "description": "Track blog performance and reader engagement",
  "filter": {"key": "source", "value": "blog"},
  "dashboard_id": null,
  "insights": [
    {"name": "Blog Pageviews (Total)", "type": "pageviews_total"},
    {"name": "Unique Blog Readers", "type": "unique_users"},
    {"name": "Blog Traffic Trend", "type": "traffic_trend"},
    {"name": "Top Blog Posts", "type": "top_pages"}
  ]
}

Note: Set dashboard_id: null for new dashboards.

Step 2: Create Dashboard#

bash

./scripts/posthog_sync.sh create blog_dashboard.json

Output:

text

Creating dashboard: Blog Analytics
Dashboard created: ID 1166599
Creating insight: Blog Pageviews (Total)
{id: 6520531, name: "Blog Pageviews (Total)"}
...
Dashboard URL: https://us.posthog.com/project/209268/dashboard/1166599

The script:

• Creates a new dashboard in your PostHog project
• Returns dashboard_id (e.g., 1166599) and project_id (e.g., 209268) in the URL
• Automatically updates your config file with the dashboard_id

Step 3: Add New Insights (Sync)#

Edit config to add new insights, then:

bash

./scripts/posthog_sync.sh sync blog_dashboard.json

Only creates NEW insights. Existing ones (matched by name) are skipped.

Step 4: Update Existing Insights#

Changed your filter? Edit config, then:

bash

./scripts/posthog_sync.sh update blog_dashboard.json

Updates ALL insights with current config settings. Use when changing filters.

Step 5: Export Existing Dashboard#

bash

./scripts/posthog_sync.sh export 1166599 > exported_dashboard.json
