Integrations

Sixteen connectors, one WhatsApp inbox.

HellouOne plugs into the CRM, calendar, store, help desk and payment tools you already run, so the AI agent can book, look up an order or send a payment link without leaving the conversation.

How it works

A connector gives the AI agent a tool, not just a data feed.

Each HellouOne connector exposes actions the AI agent can call during a conversation — check availability in Calendly, find an order in Shopify, create a Stripe payment link — and, for CRMs with two-way sync, keeps contacts and conversation history mirrored in both systems. You switch a connector on from Settings; no code is involved.

FAQ

Questions about integrations

Which plan do I need for integrations?

Connectors, the public API, the SDK and webhooks are available from the Starter plan ($49/mo). Two-way CRM sync works with GoHighLevel, HubSpot, Pipedrive and DataCRM on any plan that has the connector switched on.

My tool is not on the list. Can I still connect it?

Yes, in two ways: give the AI agent a custom tool that calls your own API endpoint, or use webhooks plus the public API to sync data from your side. Airtable also works as a simple bridge for lists, price tables and inventories.

Does the AI agent act on its own in my CRM?

Only through the actions you enable for it. A connector exposes specific actions (create a contact, book a slot, look up an order); the agent can call those and nothing else. Every action shows up in the conversation so your team can see what happened.

Can I connect several WhatsApp numbers?

Yes. Each number is an inbox in HellouOne; the free trial includes two inboxes and higher plans add more. Each inbox can have its own AI agent, team and connectors.
