Connect custom channels to help desk

Last updated: October 28, 2026

Available with any of the following subscriptions, except where noted:

Custom channels create a bridge between an external messaging service and HubSpot. By connecting a custom channel app to help desk, support reps can respond to incoming messages from their preferred messaging app, ensuring a unified customer experience.

You can install pre-built messaging apps from the HubSpot marketplace (such as TikTok, Instagram, and Slack). However, if you use a messaging service that doesn't have a native integration with HubSpot, you can build your own custom channel and connect it via API.

Once your custom channel and public app are set up, you can install it from the marketplace and connect it as a channel in help desk, enabling reps to manage conversations across all channels in one place. Learn more about creating custom channels.

In this article, learn how to connect your custom channel to help desk. To connect custom channels to the conversations inbox, follow the steps in this article.
