Is my Customer.io data secure when connected to HubSpot?
Yes. Arahi uses OAuth 2.0 for authentication — we never store your Customer.io or HubSpot passwords. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). Your marketing data is only accessed when a workflow runs, and you can revoke access at any time from your Arahi dashboard.
Can I sync data both ways between Customer.io and HubSpot?
Yes. You can set up workflows that trigger from either Customer.io or HubSpot. For example, create a workflow where Customer.io events update HubSpot, and a separate one where HubSpot changes sync back to Customer.io. Each direction is configured independently so you have full control.

No coding is required. Arahi's visual workflow builder lets you configure triggers, actions, and field mapping with clicks. If you can use Customer.io and HubSpot, you can set up the integration. Most users are running their first workflow within 10 minutes.
