Create Custom API

[張志明]

How can I create a custom API in HubSpot that can be called by external systems.

The internal processing of the custom API is to call the HubSpot standard API and add some processing logic.

Hello @張志明,

HubSpot does not support creating custom API endpoints inside HubSpot itself, there’s no native way to host server-side logic or expose custom API routes directly on the platform. But you can build an external API that calls HubSpot’s APIs and adds custom logic. That's the common and scalable approach.

Hope this will help!
