  1. Close CRM - Daily driver for SMB sales (simplest API, best value)
  2. HubSpot - Marketing + Sales alignment with rich ecosystem
  3. Salesforce - Enterprise requirements and complex workflows
  4. Cross-CRM Sync - Bidirectional sync with conflict resolution

Key deliverables:

  • API client setup with proper authentication
  • CRUD operations for leads, contacts, deals, activities
  • Webhook handlers for real-time sync
  • Pipeline automation and reporting

<quick_start> Close CRM (API Key Auth):

import httpx

class CloseClient:
    BASE_URL = "https://api.close.com/api/v1"

    def __init__(self, api_key: str):
        self.client = httpx.Client(
            base_url=self.BASE_URL,
            auth=(api_key, ""),  # Basic auth, password empty
            timeout=30.0,
        )

    def create_lead(self, data: dict) -> dict:
        response = self.client.post("/lead/", json=data)
        response.raise_for_status()
        return response.json()

    def search_leads(self, query: str) -> list:
        response = self.client.post("/data/search/", json={
            "query": {"type": "query_string", "value": query},
            "results_limit": 100
        })
        return response.json()["data"]

# Usage
close = CloseClient(os.environ["CLOSE_API_KEY"])
leads = close.search_leads("company:Coperniq")

HubSpot (Python SDK):

from hubspot import HubSpot
from hubspot.crm.contacts import SimplePublicObjectInputForCreate

client = HubSpot(access_token=os.environ["HUBSPOT_ACCESS_TOKEN"])

# Create contact
contact = client.crm.contacts.basic_api.create(
    SimplePublicObjectInputForCreate(properties={
        "email": "user@example.com",
        "firstname": "Jane",
        "lastname": "Smith"
    })
)
print(f"Created: {contact.id}")

Salesforce (JWT Bearer):

import jwt
from datetime import datetime, timedelta

class SalesforceClient:
    def __init__(self, client_id: str, username: str, private_key: str):
        self.auth_url = "https://login.salesforce.com"
        self._authenticate(client_id, username, private_key)

    def _authenticate(self, client_id, username, private_key):
        payload = {
            "iss": client_id,
            "sub": username,
            "aud": self.auth_url,
            "exp": int((datetime.utcnow() + timedelta(minutes=3)).timestamp())
        }
        assertion = jwt.encode(payload, private_key, algorithm="RS256")

        response = httpx.post(f"{self.auth_url}/services/oauth2/token", data={
            "grant_type": "urn:ietf:params:oauth:grant-type:jwt-bearer",
            "assertion": assertion
        })
        self.access_token = response.json()["access_token"]
        self.instance_url = response.json()["instance_url"]

</quick_start>

<success_criteria> A CRM integration is successful when:

  • API authentication works without errors
  • CRUD operations complete for all entity types
  • Rate limits are respected (Close: 100 req/10s, HubSpot: varies by tier)
  • Webhooks fire and process correctly
  • Data syncs bidirectionally without duplicates </success_criteria>

Close CRM (Daily Driver)

Note: Tim's primary CRM is HubSpot via Epiphan CRM MCP. Close CRM patterns are retained for reference but are not the active workflow.

Query Language (for Smart Views)

# Leads with no activity in 30 days
'sort:date_updated asc date_updated < "30 days ago"'

# High-value opportunities
'opportunities.value >= 50000 opportunities.status_type:active'

# Custom field filtering
'custom.cf_industry = "MEP Contractor"'

# Multiple trade types (your ICP)
'custom.cf_trades:HVAC OR custom.cf_trades:Electrical'

Core Operations

# Create lead with contacts
lead = close.create_lead({
    "name": "ABC Mechanical",
    "url": "https://abcmech.com",
    "contacts": [{
        "name": "John Smith",
        "title": "Owner",
        "emails": [{"email": "john@abcmech.com", "type": "office"}],
        "phones": [{"phone": "555-1234", "type": "office"}]
    }],
    "custom.cf_tier": "Gold",
    "custom.cf_source": "sales-agent"
})

# Create opportunity
opp = close._request("POST", "/opportunity/", json={
    "lead_id": lead["id"],
    "value": 50000,
    "confidence": 50,
    "status_id": "stat_xxx"  # Pipeline stage
})

# Log activity
close._request("POST", "/activity/note/", json={
    "lead_id": lead["id"],
    "note": "Initial discovery call - interested in demo"
})

Rate Limit Headers (RFC-compliant)

SOQL Query Patterns

-- Parent-child relationship (Contacts of Account)
SELECT Id, Name, (SELECT LastName, Email FROM Contacts)
FROM Account WHERE Industry = 'Technology'

-- Child-parent relationship
SELECT Id, FirstName, Account.Name, Account.Industry
FROM Contact WHERE Account.Industry = 'Technology'

-- Semi-join (Accounts with open Opportunities)
SELECT Id, Name FROM Account
WHERE Id IN (SELECT AccountId FROM Opportunity WHERE IsClosed = false)

REST API v59.0

def create_opportunity(self, data: dict) -> dict:
    """Required: Name, StageName, CloseDate."""
    response = self.client.post(
        f"{self.instance_url}/services/data/v59.0/sobjects/Opportunity/",
        headers={"Authorization": f"Bearer {self.access_token}"},
        json=data
    )
    return response.json()

# Composite API (batch up to 200 records)
def composite_create(self, records: list) -> dict:
    return self.client.post(
        f"{self.instance_url}/services/data/v59.0/composite/sobjects",
        json={"allOrNone": False, "records": records}
    )

<webhook_patterns>

Webhook Handlers

Close Webhook (FastAPI)

from fastapi import FastAPI, Request, HTTPException
import hmac, hashlib

app = FastAPI()

@app.post("/webhooks/close")
async def close_webhook(request: Request):
    body = await request.body()
    signature = request.headers.get("Close-Sig")

    expected = hmac.new(
        CLOSE_WEBHOOK_SECRET.encode(), body, hashlib.sha256
    ).hexdigest()

    if not hmac.compare_digest(signature, expected):
        raise HTTPException(401, "Invalid signature")

    data = await request.json()
    event_type = data["event"]["event_type"]

    handlers = {
        "lead.created": handle_lead_created,
        "opportunity.status_changed": handle_opp_stage_change,
    }

    if handler := handlers.get(event_type):
        await handler(data["event"]["data"])

    return {"status": "ok"}

Close Webhook Events

lead.created, lead.updated, lead.deleted, lead.status_changed
contact.created, contact.updated
opportunity.created, opportunity.status_changed
activity.note.created, activity.call.created, activity.email.created
unsubscribed_email.created

Clay MCP Enrichment (mcp__claude_ai_Clay__)

Pattern: HubSpot → Apollo → Clay → HubSpot sync

Tool Purpose
find-and-enrich-company Find and enrich company by domain or LinkedIn URL
find-and-enrich-contacts-at-company Find contacts by role/title/location at a company
find-and-enrich-list-of-contacts Find specific named contacts at their companies
add-contact-data-points Queue contact enrichment (Email, Phone, Work History, Thought Leadership)
add-company-data-points Queue company enrichment (Tech Stack, Funding, Headcount, Competitors, etc.)
