## Primary Purpose

Connect TWICE to external systems through the API, webhooks, and your account identifiers.

<AccordionGroup>
  <Accordion title="API keys">
    Create keys to authenticate against the TWICE API. The full key is shown once at creation — copy it then. Revoke a key to disable it. See [API Keys](/docs/concepts/integrations/api-keys).
  </Accordion>

  <Accordion title="Webhooks">
    Send events (such as `order.created`) to an external HTTPS URL. Create, enable or disable, and delete webhooks, reveal or rotate a webhook's signing secret, and open its delivery log to inspect payloads and redeliver individual events. See [Webhooks](/docs/concepts/integrations/webhooks).
  </Accordion>

  <Accordion title="Account ID">
    Copy your tenant ID for use in API requests and integrations.
  </Accordion>
</AccordionGroup>

<Note>
  **Webhooks** require a plan that includes them — see [plans](/docs/twice-commerce-overview#pricing).
