Apollo SDK Patterns

Overview

Production-ready patterns for Apollo.io API integration. Apollo has no official SDK — these patterns wrap the REST API (https://api.apollo.io/api/v1/) with type safety, retry logic, pagination, and bulk operations. All requests use the x-api-key header.

Prerequisites

• Completed apollo-install-auth setup
• TypeScript 5+ with strict mode

Instructions

Step 1: Type-Safe Client with Zod Validation

// src/apollo/client.ts
import axios, { AxiosInstance } from 'axios';
import { z } from 'zod';

const ConfigSchema = z.object({
  apiKey: z.string().min(10, 'API key too short'),
  baseURL: z.string().url().default('https://api.apollo.io/api/v1'),
