Overview
Use Mixpanel as a data source for Chartcastr. Connect your project with a Service Account and Chartcastr will pull active user metrics, top events, saved funnels, cohort retention, and a custom multi-event overlay to generate charts delivered automatically to Slack or email. Chartcastr connects with read-only access to your Mixpanel project — the Service Account only needs the Analyst role.Setup
Create a Mixpanel Service Account
In Mixpanel, go to Project Settings → Service Accounts and create a new account. Grant it the Analyst role on the project. Copy the username and secret — you’ll need both.
Find your Project ID
Your numeric Project ID is in your Mixpanel URL:
https://mixpanel.com/project/<PROJECT_ID>/... (or eu.mixpanel.com for EU residency).Connect in Chartcastr
In Chartcastr, go to New Connection and select Mixpanel as a source. Pick US or EU region, paste the Service Account username + secret + Project ID, and click Test & Connect.

Region: Use US for
mixpanel.com or EU for eu.mixpanel.com. The region drives which Query API host we hit and is locked once connected — disconnect and reconnect to switch regions.Confirm your pageview event
After connecting, Chartcastr auto-detects your pageview event by looking for common names (
Page Viewed, $mp_web_page_view, Page View, etc.) in your top events. You can override it with any event from your project — pick Pick a different event in the connect modal.Select a metric
Choose a chart type. Funnel metrics ask you to pick a saved funnel; the Custom Events Overlay asks you to pick up to 5 events.
Available Metrics
Chartcastr supports 12 pre-built Mixpanel metrics across six categories.Active Users

Authentication
Chartcastr uses HTTP Basic auth with your Service Account username and secret. The secret is encrypted at rest with AES-256-GCM. We never store the project token — only the SA credentials, which are read-only.Rate Limits
Mixpanel’s Query API is capped at 60 queries/hour per project with a maximum of 5 concurrent queries. Chartcastr’s pulse cadence (daily/weekly) keeps you well below the cap. If you hit the limit you’ll see a clear “rate limit hit” error in the chart preview — wait an hour and try again.Custom Events Overlay
The Custom Events Overlay chart lets you pick up to 5 event names from your project and renders them as a multi-line chart on a single shared Y axis with a fixed color palette.v1 ships with a single shared Y axis. Per-event left/right axis selection is on the v2 roadmap so high-volume and low-volume events can share a chart without one squashing the other.
