# Integrations

> Connect external services to power your workflows

Innflow integrates with dozens of external services. Each integration is powered by an OAuth credential that you connect once and use across all your workflows.

## Setting Up Integrations

<Steps>
  <Step title="Go to Credentials">
    Navigate to **Settings → Credentials** from the sidebar.
  </Step>

  <Step title="Connect a service">
    Click **New Credential** and choose the service. You will be redirected to authorize Innflow.
  </Step>

  <Step title="Use in workflows">
    Any node that needs that service will automatically have access to the credential.
  </Step>
</Steps>
