Migma API: The Developer’s Guide to Programmatic Email Perfection

In the world of development, we’ve spent decades trying to solve the "email problem." We’ve wrestled with table-based layouts, inconsistent CSS support across 40+ clients, and the endless back-and-forth between design tools and code.

Today, we’re officially opening the hood. The Migma API is now generally available, turning our AI-powered email engine into a single, programmable endpoint for your stack.

Migma API Overview

Why Programmatic Email?

The traditional workflow is broken: Figma for design → ChatGPT for copy → Manual HTML coding → Testing in Litmus → Uploading to an ESP.

Migma compresses this entire lifecycle into 30 seconds. With the API, you can now:

  • Generate on-brand content using project-specific brand memory.
  • Automate brand imports from any URL to keep styles synced.
  • Validate rendering across 40+ real devices automatically.

Core Endpoints for Your Stack

We’ve designed our API to be as intuitive as the platform itself. Here are the pillars of the Migma developer experience:

1. AI-Powered Generation

The POST /v1/projects/emails/generate endpoint is where the magic happens. It uses your stored brand context to create production-ready React Email code.

const res = await fetch('https://api.migma.ai/v1/projects/emails/generate', {
  method: 'POST',
  headers: { 'Authorization': 'Bearer API_KEY' },
  body: JSON.stringify({
    projectId: "your_project_id",
    prompt: "Create a summer sale announcement",
    webMode: true,
    languages: ["en", "es"]
  })
});

2. Real-Device Previews

Stop guessing how your code looks in Outlook 2013. Our POST /v1/emails/previews endpoint triggers automated screenshots on real hardware.

Automation Without the Code: n8n Integration

For those who prefer visual logic, our n8n integration allows you to build complex email lifecycles using drag-and-drop nodes. Whether it's syncing Shopify products or triggering abandoned cart recovery, you can automate it all without writing a single line of code.

The possibilities are limited only by your projectId.

  • Marketing Automation: Scale personalized campaigns based on user behavior.
  • E-commerce Sync: Connect Shopify or WooCommerce to generate dynamic product drops.
  • Custom CRM Tools: Trigger high-fidelity emails directly from your internal dashboards.
