Blueprint

API Substack Migration & Automation Retainer (5-7 days)

This blueprint productizes API Substack into a client retainer that bundles content migration from 60+ platforms with ongoing automated publishing workflows, giving agencies a recurring revenue stream.

Prerequisites
  • Active API Substack account with API key
  • Access to client's Substack publication and source platform (e.g., WordPress, Medium)
  • Familiarity with Make.com, Zapier, or N8N for workflow automation
  • Client approval on content migration scope and tagging structure
  • Test posts prepared to validate API calls before full migration
Execution Timeline
  • 1.Create API Substack account and generate API key
  • 2.Review API docs for posting, drafting, deleting, and tagging endpoints
  • 3.Test API connection with a sample draft via curl or Postman
  • 1.Map client's existing blog structure to Substack tags
  • 2.Set up migration workflow using API Substack's migration guides for WordPress or Medium
  • 3.Run a pilot migration of 5 posts and verify formatting
  • 1.Configure Make.com or Zapier workflow to trigger API calls for new posts
  • 2.Integrate ChatGPT or Claude to generate post summaries or titles via API
  • 3.Test automated publishing with a draft post
  • 1.Migrate remaining client posts (up to 50) via API
  • 2.Create tags and assign to migrated content
  • 3.Validate all posts are live and correctly tagged
  • 1.Document the automated publishing workflow for client handoff
  • 2.Set up ongoing monitoring for API errors or rate limits
  • 3.Deliver walkthrough session to client

ROI Logic

At $9/month with unlimited API calls, the tool cost is negligible. Charging $1,150 for a starter migration (as per productized offer) yields a margin of over 99% on tool cost alone, and the retainer model adds recurring revenue for ongoing automation management.

Deliverables
  • Migrated Substack publication with up to 50 posts and configured tags
  • Make.com or Zapier workflow for automated publishing
  • API integration documentation for client reference
  • Tag structure mapping document
  • Client walkthrough recording
Definition of Done

Client's content is fully migrated to Substack via API, automated publishing workflow is live and tested, and client has received documentation and a walkthrough session.
