Do I need an iPaaS to connect my app to Salesforce and HubSpot?

Not necessarily.

Whether you need an iPaaS depends on how much integration you want and how complex it is:

You probably don’t need an iPaaS if:

• You only need to connect to one or two systems like Salesforce and HubSpot
• The workflow is simple, like:
  • create/update contacts
  • sync leads
  • push form submissions
• You have engineering capacity to build and maintain the integration yourself
• Near-real-time sync, advanced error handling, or complex routing isn’t required

In that case, you can often use:

• Native APIs from Salesforce and HubSpot
• Webhooks
• A small custom integration service
• Middleware you host yourself

You probably do want an iPaaS if:

• You need to connect to multiple systems beyond Salesforce and HubSpot
• You want prebuilt connectors and faster setup
• You need:
  • retries / error handling
  • monitoring and alerts
  • data mapping/transformation
  • scheduled syncs
  • low-code workflows
• Non-engineers need to manage integrations
• The integration will become a core business process

Examples of iPaaS tools:

• MuleSoft
• Workato
• Boomi
• Zapier / Make (for simpler use cases)
• Tray.io

Rule of thumb

• Simple app-to-Salesforce/HubSpot sync: build it directly
• Many systems + business workflows + reliability requirements: use an iPaaS

If you want, I can help you decide based on:

1. what data you’re syncing,
2. how often it changes,
3. whether you need two-way sync,
4. and your engineering resources.
