RESTful API for Marketing Campaigns & Transactional Emails

Overview

The Mailchimp API is a RESTful interface enabling developers to automate marketing campaign management and transactional email sending. It uses JSON for all requests and responses. Key endpoints include creating/sending campaigns, managing subscriber audiences (segmentation, list updates), tracking performance (opens, clicks), and sending transactional emails via Mailchimp’s Transactional API. Use cases: integrate email marketing into e-commerce platforms, automate welcome sequences, sync customer data, and generate custom reports. It requires authentication (API key/OAuth2) and supports batch operations for efficient data handling.

Example Integration (JavaScript)

script.js JS


fetch('https://mailchimp.com/developer/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
