Instantly Local Dev Loop

Overview

Set up a local development workflow for Instantly integrations. Instantly provides a mock server at `` for testing without sending real emails or consuming API limits. This skill covers mock server usage, integration testing, and local webhook development.

Prerequisites

• Completed instantly-install-auth setup
• Node.js 18+ with TypeScript
• A separate Instantly API key for dev/test (recommended)

Instructions

Step 1: Configure Dev Environment

// src/config.ts
import "dotenv/config";

interface Config {
  baseUrl: string;
  apiKey: string;
  useMock: boolean;
}

export function getConfig(): Config {
  const useMock = process.env.INSTANTLY_USE_MOCK === "true";
  return {
    baseUrl: useMock
      ? "https://developer.instantly.ai/_mock/api/v2"
      : process.env.INSTANTLY_BASE_URL || "https://api.instantly.ai/api/v2",
    apiKey: process.env.INSTANTLY_API_KEY || "",
    useMock,
  };
}

# .env.development
INSTANTLY_API_KEY=your-dev-api-key
INSTANTLY_BASE_URL=https://api.instantly.ai/api/v2
INSTANTLY_USE_MOCK=true

# .env.production
INSTANTLY_API_KEY=your-prod-api-key
INSTANTLY_BASE_URL=https://api.instantly.ai/api/v2
INSTANTLY_USE_MOCK=false
