SYSTEM AND METHOD FOR EMBEDDING FIRST PARTY WIDGETS IN THIRD-PARTY APPLICATIONS

Methods and systems for providing a third party application with access to files stored on a server are disclosed. A method may include receiving, from a browser at a client device, a request for a file stored on the server, wherein the request is received via a web page provided by the third party application and rendered by the browser, the web page comprising an embedded user interface (UI) component associated with the server to access the file stored on the server, wherein the request includes a document identifier associated with the file, an application identifier of the third-party application, and an origin identifier, wherein the origin identifier is associated with the web page provided by the third party application and rendered by the browser. The method may further include authenticating the application identifier at the server, wherein authenticating the application identifier comprises determining whether the application identifier references a valid application, and based on the document identifier, the authenticated application identifier and the origin identifier, granting access to the file for the third party application via the embedded UI component.
