# Direct integrations

With Direct Integrations, you primarily use [checkouts](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/checkouts), along with [Drop-in payments](https://docs.digitalriver.com/digital-river-api/payments/payment-integrations-1/drop-in) or [Elements](https://docs.digitalriver.com/digital-river-api/payments/payment-integrations-1/digitalriver.js), to construct a customer's checkout and payment experience.
