# Apollo Install & Auth ## Overview Set up Apollo.io API client and configure authentication credentials. Apollo uses the `x-api-key` HTTP header for authentication against the base URL `https://api.apollo.io/api/v1/`. There is no official SDK — all integrations use the REST API directly. ## Prerequisites - Node.js 18+ or Python 3.10+ - Package manager (npm, pnpm, or pip) - Apollo.io account with API access (Basic plan or above) - API key from Apollo dashboard (Settings > Integrations > API Keys) ## Instructions ### Step 1: Install HTTP Client ```bash set -euo pipefail # Node.js npm install axios dotenv # Python pip install requests python-dotenv ``` ### Step 2: Configure API Key Apollo supports two API key types: - **Master API key** — full access to all endpoints (required for contacts, sequences, deals) - **Standard API key** — limited to search and enrichment only ```bash # Create .env file (never commit this) echo 'APOLLO_API_KEY=your-api-key-here' >> .env echo '.env' >> .gitignore ``` ### Step 3: Create Apollo Client (TypeScript) ```typescript // src/apollo/client.ts import axios, { AxiosInstance } from 'axios'; import dotenv from 'dotenv'; dotenv.config(); const BASE_URL = 'https://api.apollo.io/api/v1'; export function createApolloClient(apiKey?: string): AxiosInstance { const key = apiKey ?? process.env.APOLLO_API_KEY; if (!key) throw new Error('APOLLO_API_KEY is not set'); return axios.create({ baseURL: BASE_URL, headers: { 'Content-T...
