Generate a WordPress plugin to sync contacts with HubSpot CRM
HubSpot's official WordPress plugin is a good landing pad for tracking form submissions and chat. It becomes limiting when you need bidirectional sync, custom property mapping, company associations based on billing address, or deals automatically created from specific order types. The workarounds are either a paid add-on, a Zapier pipeline, or writing a plugin.
A custom HubSpot plugin maps your WordPress objects to HubSpot's data model with the exact properties you care about. We use Private Apps for authentication (no OAuth dance), respect the v3 API rate limits (100 per 10s), and queue writes so a slow HubSpot call never slows down WooCommerce checkout.
Why generate it instead of installing an existing plugin?
HubSpot's own WordPress plugin covers forms and tracking but does not expose the full API surface. For any non-trivial data flow (linking companies to contacts, creating deals on order, updating lifecycle stages based on user meta), you are on your own.
Third-party connectors (Zapier, Make, PieSync/Operations Hub) work for occasional volume. When WordPress is the system of record for 1000+ contacts, those connectors become expensive and slow — each sync is a round-trip through their infra.
Custom property mapping is where generic integrations fall apart. HubSpot custom properties have internal names, types, and validation rules that third-party tools cannot expose well. A plugin written around your specific schema handles this natively.
Example prompt
This is the kind of description that generates this plugin. You can start from it and tweak whatever you need before hitting generate.
Plugin name: Acme HubSpot Sync
Authentication: HubSpot Private App access token (stored in wp_options with autoload=no).
Sync rules:
1. WordPress user registration → HubSpot contact with properties: email, firstname, lastname, company, source=wordpress.
2. WooCommerce order completed → HubSpot deal (pipeline="sales", stage="closedwon") with amount=order total, dealname=order number. Associated contact via customer email.
3. User meta "role" change → update HubSpot contact property "lifecyclestage" accordingly (customer / subscriber / evangelist).
Custom property mapping: admin UI lets staff add rows of (WP source → HubSpot property name).
Rate limiting:
- Respect v3 limit of 100 requests / 10 seconds per API key.
- Queue writes; a cron running every minute drains up to 80 per tick.
- 429 response → wait the Retry-After header + jitter.
Suppression list for emails (never sync). Skip sync entirely for test-mode orders.
Admin:
- Private App token input.
- Property mapping table.
- Test sync button.
- Last 20 sync operations log.
HPOS-compatible.What the generated plugin typically includes
- HubSpot v3 client via wp_remote_post with Bearer auth header
- Service classes for Contacts, Companies, Deals with idempotent upsert by email
- Queued write pattern respecting the 100-req-per-10-s ceiling
- 429 handling with Retry-After + exponential jitter
- Admin property mapping UI and a log of recent operations
- HPOS-compatible order reads
- Suppression list + test-mode skip rules
Add custom timeline events, associate deals with companies, enrich contacts with Clearbit data — each is a hook the plugin can expose.
Frequently asked questions
Do I need a HubSpot paid plan?
The HubSpot free tier covers basic Contacts API access. For Deals you need Sales Hub (Starter tier onward). The plugin works with whatever your plan allows.
What is a Private App vs OAuth?
Private Apps are single-tenant tokens you create from your HubSpot settings. Simpler than OAuth (no redirect flow needed), recommended by HubSpot for internal integrations. We use them exclusively.
How do conflicts resolve?
WordPress is treated as the source of truth for new contacts. On field conflict (same email exists in HubSpot with a different company), the plugin updates HubSpot with WordPress values unless you add a merge rule in the prompt saying otherwise.
Is the sync bidirectional?
By default one-way WP → HubSpot. If you want changes made in HubSpot to flow back (say, updating a contact's lifecycle stage), we can add a webhook receiver listening for HubSpot's contact.propertyChange events. Describe it in the prompt.
