Getting started

PostLever is an email deployment platform. The PostLever API gives you programmatic access to your contacts, brands and the brands each contact is assigned to, and to the contact attribute schema your account defines.

All API endpoints are relative to the following base URL:

https://api.postlever.com/v1/

Every endpoint requires authentication. Your API key is on the Account Details page in the app, and must be sent with every request as an Authorization header:

Authorization: Bearer postlever_api_YOUR_KEY_HERE

Looking for the SUPPRESS or Mailer APIs? Those are Optizmo products, documented at docs.optizmo.com.
