You’re all set—your private app is now created and ready to use.

📌 Why this matters

Creating a private app lets you build custom integrations that pull HubSpot data into your own systems, automate workflows between platforms, or create specialized dashboards for your team. Unlike public marketplace apps, private apps give you granular control over exactly which data points and operations your integration can access. This means you can build lightweight, purpose-built connections that sync only the contact fields, deal properties, or campaign metrics you actually need, without the bloat or monthly fees of third-party solutions.
