File conversion API for mailboxes, documents and disks
A REST API under /api/v1 for Business workspaces: conversion catalog, jobs, uploads, downloads and webhooks. Authenticate with an organization API key.
What the API is
Version 1 lives at /api/v1. Authenticate with Authorization: Bearer and an organization key prefixed mdn_. The OpenAPI document is public at /api/v1/openapi, without a key. Other /api/ routes stay out of the search index.
Resources
List conversions from the same catalog as the product. Create jobs, upload files, follow status, download results, and subscribe to webhooks. Idempotency keys are supported on job creation so retries do not duplicate work.
Automation
The contract is meant for Zapier, Make, n8n, MCP and in-house scripts — the same operations you would click in a Business workspace. Dedicated /integrations/n8n pages will come when those connectors are a product surface, not a sentence.
What it is not
There is no anonymous file-conversion API on the marketing domain. Guest conversion stays on the website uploader. Keys are scoped to one organization; a leaked key is a workspace incident, not a cute demo.
Mailbox and disk jobs
If you are wiring a migration, the interesting operations are mailbox pairs and hypervisor disks, not JPG to PNG. Start from the conversion catalog filtered by family, then attach files the same way the UI does.
