Welcome to the lemlist API reference 🎉

Looking to integrate lemlist with other tools? Automate some of your outreach away? You’re in the right place.

API URL

All API routes live at https://api.lemlist.com/api. So, for every endpoint documented in this reference, the full URL is https://api.lemlist.com/api/{endpoint}.

Outline

The API reference is part of the larger developer docs, divided into 2 main sections:
  • User Guides: tutorials that leverage the API reference
  • API Reference (👈 you’re here): every technical detail about the API
And the API reference itself is divided into 3 main sections:
  • Getting Started (👈 you’re here): everything you need to know before using the API (authentication, rate limits, etc.)
  • Endpoints: the different endpoints available in the API, to actually get things done
  • Objects & Definitions: the different objects, their definitions and what they mean (whether in lemlist’s product or its API)

How to read the API reference

I’d say:
  1. skim through the Getting Started section (special attention on Authentication - it’s tricky)
  2. fast-forward to the API endpoints that seem relevant to you
  3. if need be, check the objects referenced in those endpoints to understand what they mean
