Need help with Mapping

[SKnebusch]

Hey, according to our IT specialists we have an integration of our own data via an API. And I try to map the data but the menu is not shown for that whereas is other integrations I can see the sync and mapping menues. What do I have to do? When clicking on the App all I get is a report about the API calls:

This really depends on the API connection and how it was built. Sometimes all the mapping is done on the backend in the connection, and those that built it would need to update it.

Hello @SKnebusch ,

Unlike HubSpot's native Data Sync integrations (e.g., Salesforce, NetSuite), custom API connections don't include a built-in UI for field mapping unless specifically designed to support it.

For your custom API integration, you'll need to handle data mapping programmatically through either:

1. API Configuration:

   • Define field mappings directly in your API logic

   • Ensure API calls (POST/PATCH) target the correct HubSpot objects and property names

2. Middleware Solutions:

   • Use integration platforms like Zapier, Workato, or custom middleware

   • Configure mappings in the middleware layer if available

Since HubSpot doesn't control the data flow in custom integrations, the standard mapping interface won't appear.

Let me know what you're trying to map specifically (e.g., contacts, deals, custom objects), and I’d be happy to help guide you through a setup or suggest an alternative approach.
