# 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
```typescript
// 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)
];

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;
}
```

### Step 2: Migration Map — Old to New
```typescript
// src/migration/apollo-migration-map.ts
interface MigrationRule {
  description: string;
  find: string | RegExp;
  replace: string;
  breaking: boolean;
}

const MIGRATION_RULES: MigrationRule[] = [
  // Auth: query param -> header
  {
    description: 'Move API key from query param to x-api-key header',
    find: /params:\s*\{[^}]*api_key[^}]*\}/g,
    replace: "headers: { 'x-api-key': process.env.APOLLO_API_KEY! }",
    breaking: true,
  },
  // Base URL
  {
    description: 'Update base URL from /v1 to /api/v1',
    find: 'api.apollo.io/v1',
    replace: 'api.apollo.io/api/v1',
    breaking: true,
  },
  // People Search endpoint
  {
    description: 'Migrate people search to new endpoint',
    find: '/people/search',
    replace: '/mixed_people/api_search',
    breaking: true,
  },
  // People Search parameters
  {
    description: 'Rename q_organization_domains to q_organization_domains_list',
    find: 'q_organization_domains:',
    replace: 'q_organization_domains_list:',
    breaking: false,
  },
  // Organization Search endpoint
  {
    description: 'Migrate org search to new endpoint',
    find: '/organizations/search',
    replace: '/mixed_companies/search',
    breaking: true,
  },
];
```

### Step 3: Build a Feature-Flagged Migration
```typescript
// src/migration/feature-flags.ts
const flags = {
  useNewSearchEndpoint: process.env.FF_NEW_SEARCH === 'true',
  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! } };
}
```

### Step 4: Run Parallel Comparison
```typescript
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})`);
  }
}
```

### Step 5: Post-Migration Cleanup
```bash
# 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"
```

## Output
- API usage audit identifying current and deprecated patterns
- Migration rule map for auth, base URL, and endpoint changes
- Feature-flagged migration with environment variable controls
- Shadow testing for comparing old vs new API responses
- Post-migration cleanup script

## Error Handling
| 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 |
