User interface for searching and generating graphical objects linked to third-party content

A computer-implemented method comprising:

• in response to a user request received at a content-creation field of a graphical user interface of a client application operating on a client device, causing display of a link-creation window comprising a first list of selectable elements, each selectable element of the first list of selectable elements corresponding to a content item provided by a particular content provider different than a content provider associated with the client application;
• in response to a user input provided to the link-creation window, generating an application programming interface call to the particular content provider using at least a portion of the user input;
• in response to the application programming interface call, receiving content of one or more content items managed by the particular content provider;
• rendering, within the link-creation window, the a second list of elements corresponding to the content of the one or more content items received in response to the application programming interface call;
• and
• in response to a user selection of an element of the second list of elements, render a selectable graphical object within the content-creation field, the selectable graphical object including at least a portion of content of the one or more content items.

A computer-implemented method of rendering remotely hosted data in a graphical user interface, the computer-implemented method comprising:

• causing display of the graphical user interface on a client device operating a client application, the graphical user interface having a content-creation field configured to receive text input via the client device;
• in response to receiving a first user input, causing a display of a link-creation window within the graphical user interface, the link-creation window comprising a link-creation input field and a set of tabs, each tab of the set of tabs associated with an external platform of a set of registered external platforms;
• in response to receiving a second user input to the link-creation input field, analyzing the second user input and generating an application programming interface call to a respective external platform using at least a portion of the second user input, the respective external platform selected based on a currently selected tab of the set of tabs;
• accessing, using the application programming interface call, metadata hosted by the external platform, the metadata corresponding to one or more content items provided by the external platform;
• causing display of a list of elements corresponding to the one or more content items, each element of the list of elements corresponding to a content item of the one or more content items;
• and
• in response to a user selection of an element of the list of elements, rendering a selectable graphical object within the content-creation field, the selectable graphical object including a least a portion of content of a respective content item provided by the external platform.
