Where can I find the REST API Schema?

Precisely. It’s speaks to the programmers prowess designing (any API), but certainly RESTful ones. The design appears to makes assumptions about the user language choices (e.g., javascript - the loosey-goosey 4th generation language that accepts all, rejects nothing language).

Hi all, thank you for your patience here!

We’re excited to announce the beta release of the OpenAPI specification and Typescript types for the Figma REST API in the open source figma/rest-api-spec repository.

As you may know, OpenAPI is a specification for describing HTTP APIs in a language-agnostic manner. It has a large ecosystem of tools to let you generate API documentation, client SDKs, and more. We also provide custom Typescript types generated from the OpenAPI specification for those of you with Typescript codebases to make it easy to write type-safe code out of the box.
