# Make a Guest Donation
source: https://developer.mastercard.com/donations/documentation/use-cases/make-donations/guest-donation/index.md

## Overview {#overview}

Guest donations provide a fast and easy way for individuals to implement and support a cause without committing to create and maintain a donor account. However, the lack of a profile means that the organization offering this solution has limited opportunities to engage these donors for future contributions, and each guest donation stands alone without any historical data to inform future outreach.
Note: A donation can be made by using the **Guest Donation** endpoint with all the card and donor details included in the request. But as these details are not registered, you cannot retrieve any historical data for future outreach or engagement.
