# Connect to Salesforce APIs to Interact with Marketing Cloud

How you connect an API depends on which API you plan to use. To use REST-based APIs, including REST API, Bulk API 2.0, Data 360 Connect API, and Direct Email Send API, create an external client app with the appropriate OAuth settings. See [Connect to REST-based APIs](https://developer.salesforce.com/docs/marketing/marketing-cloud-growth/guide/mc-connect-apis-rest.md), [Connect to Data 360 Connect API](https://developer.salesforce.com/docs/marketing/marketing-cloud-growth/guide/mc-connect-apis-data-cloud.md), and [Connect to Direct Email Send API](https://developer.salesforce.com/docs/marketing/marketing-cloud-growth/guide/mc-connect-apis-direct-send.md).

To use SOAP API, download a WSDL file and authenticate with a user account. See [Connect to SOAP API](https://developer.salesforce.com/docs/marketing/marketing-cloud-growth/guide/mc-connect-apis-soap.md).
