Apollo Hello World

Overview

Minimal working example demonstrating the three core Apollo.io API operations: people search, person enrichment, and organization enrichment. Uses the correct x-api-key header and api.apollo.io/api/v1/ base URL.

Prerequisites

Completed apollo-install-auth setup
Valid API key configured in APOLLO_API_KEY environment variable

Instructions

Step 1: Search for People (No Credits Consumed)

The People API Search endpoint finds contacts in Apollo's 275M+ database. This endpoint is free — it does not consume enrichment credits, but it also does not return emails or phone numbers.

// hello-apollo.ts
import axios from 'axios';

const client = axios.create({
  baseURL: 'https://api.apollo.io/api/v1',
  headers: {
    'Content-Type': 'application/json',
    'x-api-key': process.env.APOLLO_API_KEY!,
  },
});

// People Search — POST /mixed_people/api_search
async function searchPeople() {
  const { data } = await client.post('/mixed_people/api_search', {
    q_organization_domains_list: ['apollo.io'],
    person_titles: ['engineer'],
    person_seniorities: ['senior', 'manager'],
    page: 1,
    per_page: 10,
  });

  console.log(`Found ${data.pagination.total_entries} contacts`);
  data.people.forEach((person: any) => {
    console.log(`  ${person.name} — ${person.title} at ${person.organization?.name}`);
  });
  return data;
}

searchPeople().catch(console.error);

Step 2: Enrich a Single Person (Consumes 1 Credit)

The People Enrichment endpoint returns full contact details including email and phone.

// Enrich by email, LinkedIn URL, or name+domain combo
async function enrichPerson() {
  const { data } = await client.post('/people/match', {
    email: 'tim@apollo.io',
    // Alternative identifiers:
    // linkedin_url: 'https://www.linkedin.com/in/...',
    // first_name: 'Tim', last_name: 'Zheng', organization_domain: 'apollo.io',
    reveal_personal_emails: false,
    reveal_phone_number: false,
  });

  if (!data.person) {
    console.log('No match found');
    return;
  }

  const p = data.person;
  console.log(`Name:     ${p.name}`);
  console.log(`Title:    ${p.title}`);
  console.log(`Email:    ${p.email}`);
  console.log(`Company:  ${p.organization?.name}`);
  console.log(`LinkedIn: ${p.linkedin_url}`);
}

Step 3: Enrich an Organization (Consumes 1 Credit)

// Organization Enrichment — GET /organizations/enrich
async function enrichOrg() {
  const { data } = await client.get('/organizations/enrich', {
    params: { domain: 'apollo.io' },
  });

  const org = data.organization;
  if (!org) { console.log('No org found'); return; }

  console.log(`Company:    ${org.name}`);
  console.log(`Industry:   ${org.industry}`);
  console.log(`Employees:  ${org.estimated_num_employees}`);
  console.log(`Revenue:    ${org.annual_revenue_printed}`);
  console.log(`HQ:         ${org.city}, ${org.state}, ${org.country}`);
  console.log(`Tech Stack: ${org.current_technologies?.slice(0, 5).map((t: any) => t.name).join(', ')}`);
}

Step 4: Python Equivalent

import os, requests

API_KEY = os.environ['APOLLO_API_KEY']
BASE = 'https://api.apollo.io/api/v1'
HEADERS = {'Content-Type': 'application/json', 'x-api-key': API_KEY}

# People search (free)
resp = requests.post(f'{BASE}/mixed_people/api_search', headers=HEADERS, json={
    'q_organization_domains_list': ['apollo.io'],
    'person_titles': ['engineer'],
    'page': 1, 'per_page': 5,
})
for p in resp.json().get('people', []):
    print(f"  {p['name']} — {p.get('title', 'N/A')}")

# Org enrichment (1 credit)
resp = requests.get(f'{BASE}/organizations/enrich',
    headers=HEADERS, params={'domain': 'apollo.io'})
org = resp.json().get('organization', {})
print(f"Company: {org.get('name')} ({org.get('estimated_num_employees')} employees)")

Output

People search results (name, title, company — no emails)
Enriched person with email, phone, LinkedIn URL
Enriched organization with industry, headcount, revenue, tech stack

Examples

Start with the free people search against an organization you are authorized to research and confirm the credentials, response shape, and pagination without requesting contact details. For the first credit-consuming check, use a public organization domain and set a one-credit test budget; retain only the returned company-level fields needed to verify the integration. Do not use a real person’s email as a tutorial fixture or print a response containing personal contact data. If authentication fails, the response is empty, or the budget guard is unavailable, stop before enrichment and correct the configuration.

Error Handling

Error	Cause	Solution
401 Unauthorized	Missing or invalid `x-api-key` header	Check `APOLLO_API_KEY` env var
422 Unprocessable	Malformed request body	Verify JSON payload structure
429 Rate Limited	Exceeded requests/minute	Wait and retry with exponential backoff
Empty `people` array	No matches for filters	Broaden titles/seniority or use different domain
