API Integration

Integrate email validation directly into your Constant Contact workflow:

// Constant Contact API - Remove invalid contacts
const axios = require("axios");

const API_KEY = process.env.CONSTANT_CONTACT_API_KEY;
const BASE_URL = "https://api.constantcontact.com/v3";

  Authorization: `Bearer ${API_KEY}`,
  "Content-Type": "application/json",
};

// Get all contacts
