# Apollo Webhooks & Events ## Overview Build event-driven integrations with Apollo.io. Apollo does not have a native webhook system like Stripe — instead, you build real-time sync by **polling** the API for changes or using **third-party webhook platforms** (Zapier, Pipedream, Make) that trigger on Apollo events. This skill covers both approaches plus the Contact Stages and Tasks APIs for workflow automation. ## Prerequisites - Apollo account with master API key - Node.js 18+ with Express - For polling: a scheduler (cron, Cloud Scheduler, BullMQ) - For webhook platforms: Zapier/Pipedream/Make account ## Instructions ### Step 1: Poll for Contact Changes Since Apollo lacks native webhooks, poll the Contacts Search API for recently updated records. ```typescript // src/sync/contact-poller.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! }, }); interface SyncState { lastSyncAt: string; // ISO timestamp } export async function pollContactChanges(state: SyncState) { const { data } = await client.post('/contacts/search', { sort_by_field: 'contact_updated_at', sort_ascending: false, per_page: 100, }); const lastSync = new Date(state.lastSyncAt); const newChanges = data.contacts.filter( (c: any) => new Date(c.updated_at) > lastSync, ); if (newChanges.length > 0) { console.log(`Found ${newChanges.len...
