# Connect your data

Connect the systems that hold your customer, subscription, payment, support and engagement data

Churned reads from the systems you already use and writes scores, audiences and next best actions back to them. Integrations are grouped by what they deliver:

* [CRM and sales](/churned-docs/integrations/crm-and-sales.md): accounts, contacts, deals, account-manager activity
* [Marketing automation](/churned-docs/integrations/marketing-automation.md): campaign engagement in, audiences and actions out
* [Support and feedback](/churned-docs/integrations/support-and-feedback.md): tickets, conversations, surveys
* [Billing and commerce](/churned-docs/integrations/billing-and-commerce.md): subscriptions, orders, payments
* [Data platforms and analytics](/churned-docs/integrations/data-platforms-and-analytics.md): warehouses, databases, product analytics

Every integration page follows the same steps:

1. **Access the integration** in Churned under Settings, Integrations, and open the card.
2. **Retrieve credentials** in the external system as described on the integration page.
3. **Enter the credentials** in the card and save.
4. **Verify** that the card shows Activated and that data arrives in the next daily run.

The **View docs** link on every integration card opens the matching page here.
