Building a Real-Time Company Monitor with Pounce Webhooks

Most competitive intelligence is backwards-looking. You find out about a new competitor, a prospect's pivot, or a market shift weeks or months after it happens. Pounce webhooks flip this: you can set up webhook endpoints to be notified when entities matching your filters are indexed or updated.

This guide shows you how to build a company monitoring system.

What Pounce Webhooks Support

  • entity.created — A new company matching your filters was indexed
  • entity.updated — An existing company's data was updated

Webhooks can be configured to notify you about entity changes. Events are dispatched as entities are indexed from official sources.

Architecture

Implementation

Step 1: Create a Webhook Endpoint

from fastapi import FastAPI, Request import httpx app = FastAPI() SLACK_WEBHOOK = "https://hooks.slack.com/services/YOUR/SLACK/WEBHOOK" @app.post("/webhooks/pounce") async def handle_pounce_webhook(request: Request): payload = await request.json() event_type = payload.get("event") company = payload.get("data", {}) if event_type == "entity.created": message = ( f"New company registered: *{company.get('canonical_name')}*\n" f"Country: {company.get('country')}\n" f"Registry ID: {company.get('id')}\n" f"Purpose: {company.get('description', 'N/A')}" ) elif event_type == "entity.updated": message = ( f"Company updated: *{company.get('canonical_name')}*\n" f"Changes: {payload.get('changes', {})}" ) else: return {"status": "ignored"} async with httpx.AsyncClient() as client: await client.post(SLACK_WEBHOOK, json={"text": message}) return {"status": "processed"}

Step 2: Register the Webhook with Pounce

import requests headers = {"X-API-Key": "YOUR_POUNCE_API_KEY"} webhook = requests.post( "https://api.pounce.ch/api/v1/v2/webhooks", headers=headers, json={ "url": "https://your-domain.com/webhooks/pounce", "events": ["entity.created", "entity.updated"], "filters": { "country": "CH", "q": "software OR saas OR technology" } } ) print(f"Webhook ID: {webhook.json()['id']}")

Step 3: Enrich on Arrival

When a new company triggers your webhook, you probably want more than registry basics. Chain the webhook with an enrichment call:

@app.post("/webhooks/pounce") async def handle_pounce_webhook(request: Request): payload = await request.json() if payload.get("event") != "entity.created": return {"status": "skipped"} entity_id = payload["data"]["id"] async with httpx.AsyncClient() as client: enriched = await client.get( f"https://api.pounce.ch/api/v1/v2/entities/{entity_id}", headers={"X-API-Key": "YOUR_KEY"} ) company = enriched.json() # Now you have the full profile: categories, description, employees await save_to_database(company) await notify_sales_team(company) return {"status": "enriched"}

Use Cases
