Apollo Upgrade Migration

Current State

!npm list axios 2>/dev/null | head -5

Overview

Plan and execute safe upgrades for Apollo.io API integrations. Apollo has made several breaking changes historically (query param auth to header auth, endpoint URL changes, new search endpoints). This covers auditing current usage, building compatibility layers, and migrating safely.

Prerequisites

Valid Apollo API key
Node.js 18+

Instructions

Step 1: Audit Current API Usage

// src/scripts/api-audit.ts
import { execSync } from 'child_process';

interface EndpointUsage { endpoint: string; files: string[]; status: 'current' | 'deprecated'; }

const ENDPOINT_MAP = [
  // Current endpoints
  { pattern: '/mixed_people/api_search', status: 'current' as const },
  { pattern: '/mixed_companies/search', status: 'current' as const },
  { pattern: '/people/match', status: 'current' as const },
  { pattern: '/people/bulk_match', status: 'current' as const },
  { pattern: '/organizations/enrich', status: 'current' as const },
  { pattern: '/contacts/search', status: 'current' as const },
  { pattern: '/emailer_campaigns', status: 'current' as const },
  { pattern: '/email_accounts', status: 'current' as const },
  { pattern: '/opportunities', status: 'current' as const },
  // Deprecated patterns
  { pattern: '/people/search', status: 'deprecated' as const },  // old search endpoint
  { pattern: '/organizations/search', status: 'deprecated' as const },
  { pattern: 'api_key.*=', status: 'deprecated' as const },  // query param auth
  { pattern: 'api.apollo.io/v1', status: 'deprecated' as const },  // old base URL (should be /api/v1)
];

function auditUsage(srcDir: string = 'src'): EndpointUsage[] {
  const results: EndpointUsage[] = [];
  for (const ep of ENDPOINT_MAP) {
    try {
      const files = execSync(
        `grep -rl "${ep.pattern}" ${srcDir} --include="*.ts" --include="*.js" 2>/dev/null`,
        { encoding: 'utf-8' },
      ).trim().split('\n').filter(Boolean);
      if (files.length > 0) results.push({ endpoint: ep.pattern, files, status: ep.status });
    } catch { /* no matches */ }
  }

  console.log('=== Apollo API Usage Audit ===');
  for (const r of results) {
    const icon = r.status === 'deprecated' ? 'WARN' : 'OK';
    console.log(`${icon} ${r.endpoint} (${r.files.length} files)`);
    r.files.forEach((f) => console.log(`     ${f}`));
  }
  const deprecated = results.filter((r) => r.status === 'deprecated');
  if (deprecated.length > 0) {
    console.log(`\n${deprecated.length} deprecated pattern(s) found — migration needed`);
  }
  return results;
}

    breaking: true,
  },
  // Base URL

    replace: '/mixed_people/api_search',
    breaking: true,

    find: 'q_organization_domains:',
    replace: 'q_organization_domains_list:',
    breaking: false,
  },
  // Organization Search endpoint
  {
    description: 'Migrate org search to new endpoint',
    find: '/organizations/search',

];

// src/migration/feature-flags.ts
const flags = {

  useHeaderAuth: process.env.FF_HEADER_AUTH === 'true',
  useNewBaseUrl: process.env.FF_NEW_BASE_URL === 'true',
};

export function getSearchEndpoint(): string {
  return flags.useNewSearchEndpoint ? '/mixed_people/api_search' : '/people/search';
}

export function getBaseUrl(): string {
  return flags.useNewBaseUrl ? 'https://api.apollo.io/api/v1' : 'https://api.apollo.io/v1';
}

export function getAuthConfig(): Record<string, any> {
  if (flags.useHeaderAuth) {
    return { headers: { 'x-api-key': process.env.APOLLO_API_KEY! } };
  }
  return { params: { api_key: process.env.APOLLO_API_KEY! } };
}

async function shadowTest(searchParams: Record<string, any>) {
  const oldClient = axios.create({ baseURL: 'https://api.apollo.io/v1', params: { api_key: process.env.APOLLO_API_KEY } });
  const newClient = axios.create({ baseURL: 'https://api.apollo.io/api/v1', headers: { 'x-api-key': process.env.APOLLO_API_KEY! } });

  const [oldResult, newResult] = await Promise.allSettled([
    oldClient.post('/people/search', searchParams),
    newClient.post('/mixed_people/api_search', searchParams),
  ]);

  console.log('Shadow test results:');
  console.log(`  Old: ${oldResult.status === 'fulfilled' ? oldResult.value.status : 'FAIL'}`);
  console.log(`  New: ${newResult.status === 'fulfilled' ? newResult.value.status : 'FAIL'}`);

  if (oldResult.status === 'fulfilled' && newResult.status === 'fulfilled') {
    const oldCount = oldResult.value.data.people?.length ?? 0;
    const newCount = newResult.value.data.people?.length ?? 0;
    console.log(`  Results match: ${oldCount === newCount} (old: ${oldCount}, new: ${newCount})`);
  }
}

# Find remaining deprecated patterns
grep -rn "api.apollo.io/v1[^/]" src/ --include="*.ts" || echo "No old base URL found"
grep -rn "api_key.*=" src/ --include="*.ts" | grep -v "x-api-key" || echo "No query param auth found"
grep -rn "/people/search" src/ --include="*.ts" | grep -v "mixed_people" || echo "No old search endpoint found"

echo "Cleanup complete. Remove feature flags: FF_NEW_SEARCH, FF_HEADER_AUTH, FF_NEW_BASE_URL"

Issue	Resolution
Audit finds deprecated patterns	Apply migration rules file by file
Shadow test results differ	Check parameter name changes (e.g., `q_organization_domains` vs `_list`)
Feature flag issues	Disable flag immediately (`FF_*=false`)
Old endpoints still work	Apollo maintains backward compatibility, but migrate proactively
