Supercast is a private podcast platform. Outpost integrates with Supercast to provision per-member private feed URLs for qualifying subscribers.

​
How it works

Supercast generates a unique private RSS feed URL for each subscriber. Unlike Transistor (which manages subscriptions centrally), Supercast stores each member’s private feed URL directly on their Outpost record. When the display feed option is enabled in the integration’s advanced settings, each member gets two Supercast values saved on their record:
  • SUPERCAST_FEED: their unique private feed URL
  • SUPERCAST_SUBDOMAIN: their Supercast subdomain
You can include these in email templates using the merge fields below. With the display-feed option off (the default), Outpost stores only the member’s Supercast IDs and the merge fields stay empty.

​
Setup

  1. In Supercast, get your API credentials from Settings → API
  2. In Outpost, go to Settings → Integrations → Supercast
  3. Enter your Supercast API key and podcast ID
  4. Configure which Outpost tier(s) grant Supercast access

​
Delivering feed URLs to members

When a member subscribes to a qualifying tier, Outpost:
  1. Requests a private feed URL from Supercast
  2. Saves the feed URL on the member’s record
  3. Triggers an email to the member with their private feed URL
Use an email template with the %SUPERCAST_FEED_URL% merge field to include the member’s unique URL in the delivery email. Alternatively, set the integration’s welcome email method to Supercast and Supercast sends its own welcome email instead of Outpost.

​
Feed URL persistence

A member’s Supercast feed URL is persistent: it doesn’t change when they cancel and resubscribe. If you want to revoke access on cancellation, configure Outpost to deactivate the feed URL via Supercast, which makes it stop working.
