Frequently Asked Questions – HubSpot App Development
1. What is a HubSpot app and why would my business need one?
A HubSpot app is a custom integration or extension that connects HubSpot CRM to third-party systems or enhances native HubSpot functionality. It allows your business to automate workflows, sync data, display custom dashboards, and create custom user experiences within HubSpot.
2. What's the difference between a public and private HubSpot app?
A public app is listed on the HubSpot Marketplace and can be installed by any user with access. A private app is custom-built for your internal business use, offering deeper control, security, and custom integration with your unique tech stack.
3. Can you build apps that integrate HubSpot with other CRMs or tools?
Absolutely. With our OOPS platform, we build robust integrations with tools like Salesforce, Zoho, GoHighLevel, QuickBooks, Zendesk, Slack, and more. These integrations can sync contacts, activities, tickets, and even custom objects.
4. Are the apps secure and compliant with HubSpot's guidelines?
Yes. Every app we build adheres to HubSpot’s app security and review guidelines, including OAuth 2.0 for authentication, secure token storage, rate-limiting controls, and GDPR compliance where needed.
5. How long does it take to build a HubSpot app?
It depends on the scope. A simple integration or workflow extension may take 1–2 weeks, while a full-featured public app with marketplace readiness could take 4–8 weeks. We always start with a discovery session to plan your timeline and budget effectively.
