# HubSpot Integration

Expert patterns for HubSpot CRM integration including OAuth authentication,
CRM objects, associations, batch operations, webhooks, and custom objects.
Covers Node.js and Python SDKs.

## Patterns

### OAuth 2.0 Authentication

Secure authentication for public apps

**When to use**: Building public app or multi-account integration

### Template

// OAuth 2.0 flow for HubSpot
import { Client } from "@hubspot/api-client";

// Environment variables
const CLIENT_ID = process.env.HUBSPOT_CLIENT_ID;
const CLIENT_SECRET = process.env.HUBSPOT_CLIENT_SECRET;
const REDIRECT_URI = process.env.HUBSPOT_REDIRECT_URI;
const SCOPES = "crm.objects.contacts.read crm.objects.contacts.write";

// Step 1: Generate authorization URL
function getAuthUrl(): string {
  const authUrl = new URL("https://app.hubspot.com/oauth/authorize");
  authUrl.searchParams.set("client_id", CLIENT_ID);
  authUrl.searchParams.set("redirect_uri", REDIRECT_URI);
  authUrl.searchParams.set("scope", SCOPES);
  return authUrl.toString();
}

// Step 2: Handle OAuth callback
async function handleOAuthCallback(code: string) {
  const response = await fetch("https://api.hubapi.com/oauth/v1/token", {
    method: "POST",
    headers: { "Content-Type": "application/x-www-form-urlencoded" },
    body: new URLSearchParams({
      grant_type: "authorization_code",
      client_id: CLIENT_ID,
      client_secret: CLIENT_SECRET,
      redirect_uri: REDIRECT_URI,
      code: code,
    }),
  });

  const tokens = await response.json();
  // {
  //   access_token: "xxx",
  //   refresh_token: "xxx",
  //   expires_in: 1800  // 30 minutes
  // }

  // Store tokens securely
  await storeTokens(tokens);

  return tokens;
}

// Step 3: Refresh access token (before expiry)
async function refreshAccessToken(refreshToken: string) {
  const response = await fetch("https://api.hubapi.com/oauth/v1/token", {
    method: "POST",
    headers: { "Content-Type": "application/x-www-form-urlencoded" },
    body: new URLSearchParams({
      grant_type: "refresh_token",
      client_id: CLIENT_ID,
      client_secret: CLIENT_SECRET,
      refresh_token: refreshToken,
    }),
  });

  return response.json();
}

// Step 4: Create authenticated client
function createClient(accessToken: string): Client {
  const hubspotClient = new Client({ accessToken });
  return hubspotClient;
}

### Notes

- Access tokens expire in 30 minutes
- Refresh tokens before expiry
- Store refresh tokens securely
- Rotate tokens every 6 months

### Private App Token

Authentication for single-account integrations

**When to use**: Building internal integration for one HubSpot account

### Template

// Private App Token - simpler for single account
import { Client } from "@hubspot/api-client";

// Create client with private app token
const hubspotClient = new Client({
  accessToken: process.env.HUBSPOT_PRIVATE_APP_TOKEN,
});

// Private app tokens don't expire
// But should be rotated every 6 months for security

// Example: Get contacts
async function getContacts() {
  try {
    const response = await hubspotClient.crm.contacts.basicApi.getPage(
      100,  // limit
      undefined,  // after cursor
      ["firstname", "lastname", "email", "phone"],  // properties
    );

    return response.results;
  } catch (error) {
    if (error.code === 429) {
      // Rate limited - implement backoff
      const retryAfter = error.headers?.["retry-after"] || 10;
      await sleep(retryAfter * 1000);
      return getContacts();
    }
    throw error;
  }
}

// Python equivalent
// from hubspot import HubSpot
//
// client = HubSpot(access_token=os.environ["HUBSPOT_PRIVATE_APP_TOKEN"])
//
// contacts = client.c
