Technical FAQs — Integrations

We implement smart throttling, batch processing, and queue systems. For high-volume syncs, we use parallel workers with dynamic rate adjustment.
Absolutely. We configure incoming webhooks from external systems to HubSpot, and outgoing webhooks from HubSpot to your apps.
