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)
