The Designs API offers the ability to manage assets stored in the Twilio SendGrid Design Library.
The Design Library is a feature-rich email layout tool and media repository. You can build designs for all your email needs, 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.
