Apollo Reference Architecture

Overview

Production-ready reference architecture for Apollo.io integrations. Layered design with API client, service layer, background jobs, database models, CRM sync, and deals pipeline — all built around Apollo's REST API with correct endpoints and x-api-key authentication.

Prerequisites

Apollo master API key
Node.js 18+ with TypeScript
PostgreSQL for data layer
Redis for job queues

Client	Retry with backoff, circuit breaker for prolonged outages
Service	Cache fallback on failure, credit budget enforcement
Jobs	3 retries with exponential backoff, dead letter after max
API	Structured JSON error responses with error codes
