# Connect Flowella to HubSpot, Customer.io and other tools

> Compare Flowella's native HubSpot integration, its Customer.io set-up and the REST API and webhooks that connect WhatsApp to any other CRM or tool.

Flowella works on its own and alongside the tools you already use. With WhatsApp connected and nothing else, you can use the Inbox, templates and bulk sends. Integrations add the rest: building Flows from your forms, sending from your CRM's automations, and getting answers and replies back into your customer records. This page shows how each integration connects and what it gives you.

## Choose an integration

| Integration | How it connects | What you can do |
| - | - | - |
| [HubSpot](https://knowledge.flowella.io/hubspot/setup.md) | Native app, connected in **Settings**, then **HubSpot** | Build Flows from HubSpot marketing forms, send from HubSpot workflows, receive answers as form submissions, log WhatsApp activity on contacts, and bring conversations into the HubSpot inbox. |
| [Customer.io](https://knowledge.flowella.io/integrations/customer-io.md) | Customer.io webhook actions, the Flowella API and outbound webhooks | Send templates and Flows from Customer.io campaigns, and optionally sync inbound WhatsApp messages back to Customer.io. |
| Any other system | The [Flowella REST API](https://knowledge.flowella.io/api-reference/introduction.md) and [outbound webhooks](https://knowledge.flowella.io/api-reference/webhooks.md) | Send templates, manage contacts and opt-outs, and react to messages and delivery events from your own code or automation tool. |

## HubSpot

HubSpot is Flowella's native integration. Once you connect your HubSpot account:

* Flowella builds WhatsApp Flows from your HubSpot marketing forms and keeps the form list up to date.
* Flow answers return to the original HubSpot form as a form submission, and Flowella logs a **Form Completed** event on the contact.
* Flowella's workflow actions send templates, Flows and messages from HubSpot workflows. These need HubSpot workflows, which come with Professional and Enterprise plans.
* Replies, sent messages and read messages appear on the contact timeline, and each one can start a workflow.
* The custom channel brings WhatsApp conversations into HubSpot's conversations inbox. It needs Sales Hub or Service Hub Professional or Enterprise.

Start with [Connect HubSpot](https://knowledge.flowella.io/hubspot/setup.md), then see [Architecture](https://knowledge.flowella.io/essentials/architecture.md) for how data moves between HubSpot, Flowella and Meta. The [workflow guides](https://knowledge.flowella.io/hubspot/workflows/overview.md) show complete HubSpot recipes for common use cases.

## Customer.io

A webhook action in a Customer.io campaign calls Flowella to send an approved template to each person who reaches it. You can also send each inbound WhatsApp message to a Customer.io webhook-triggered automation. There is no app to install: you build both directions with standard Customer.io actions. See [Customer.io](https://knowledge.flowella.io/integrations/customer-io.md).

## Other CRMs and tools

Any system that can make HTTP requests can use Flowella through the REST API, and any system that can receive them can react to Flowella's outbound webhooks.

* **Send messages**: queue templates with `POST /v1/templates/send`, or send messages with `POST /v1/messages`.
* **Keep records in step**: create and update contacts, and read opt-outs.
* **React to events**: receive `message.received`, delivery statuses and template status changes as signed webhooks.

The interactive API docs include quickstarts for Salesforce, Zoho CRM, SurveyMonkey, Typeform and n8n. See [Developer resources](https://knowledge.flowella.io/api-reference/introduction.md#developer-resources).
