# Designs API

The Designs API offers the ability to manage assets stored in the Twilio SendGrid [Design Library](https://mc.sendgrid.com/design-library/my-designs).

The Design Library is a feature-rich email layout tool and media repository. You can [build designs for all your email needs](/docs/sendgrid/ui/sending-email/working-with-marketing-campaigns-email-designs/), including Single Sends, Automations, and Dynamic Templates.

You can also duplicate and then modify one of the pre-built designs provided by Twilio SendGrid to get you started.

The Designs API provides a RESTful interface for creating new designs, retrieving a list of existing designs, duplicating or updating a design, and deleting a design.
