Automating B2B Lead Generation: A Technical Guide to LinkedIn & Apollo APIs
By Raghav Shah•
Cold outreach is a numbers game. By building automated scraper scripts, sales teams can capture thousands of target emails and LinkedIn profiles hourly.
Prospecting limits on LinkedIn and Apollo
LinkedIn restricts manual profile views, and copy-pasting data from Apollo to spreadsheets takes hours. This restricts pipelines and causes sales rep burnout.
The Solution: Lead Generator Tech Architecture
We can write a backend script that connects to the Apollo search API, filters targets by company size/funding, cleans contact info, and queues profiles for automated outreach.
Apollo.io B2B Person Search API Request
# Python Apollo API search script
import requests
def search_prospects(api_key, title, geography):
url = "https://api.apollo.io/v1/people/match"
headers = {"Content-Type": "application/json", "Cache-Control": "no-cache"}
data = {"api_key": api_key, "q_organization_domains": "google.com", "person_titles": [title]}
response = requests.post(url, json=data, headers=headers)
return response.json()Key Insights & Takeaways
- ✓ API automation searches contacts 100x faster than manual copy-pasting
- ✓ Validated data filters exclude bouncing emails and inactive profiles
- ✓ Exporting directly to Google Sheets or CRMs keeps dashboards organized
