Take a look at the apps we have developed
We're always looking for new ways to extend HubSpot's abilities.
Custom API Workflow Action
HubSpot workflows are powerful, but they stop at your HubSpot data. The Custom API Workflow Action bridges that gap by letting you send HTTP requests to any external API directly from a workflow step, no code, no middleware, no Zapier required.

Sequence Workflow Actions
Enroll and unenroll contacts in sales sequences directly from your HubSpot workflows.
No Sales Hub Enterprise required.
