HeyMilo has two API versions. Use v2 for all new integrations.

Start here (v2)

  1. Read the v2 API Overview for auth, response shapes, and migration notes from v1.
  2. Browse endpoint docs in v2 API Reference (generated from our OpenAPI spec).
  3. Try a quickstart guide if you want a full walkthrough.

Common v2 endpoints

On v1 already? The Legacy API (v1) docs are still available, but we recommend migrating to v2. See the endpoint mapping table in the overview.
