Hello Discourse,

I want to create a custom theme component to render HTML from third-party API. I did look at the [Brand Header](https://meta.discourse.org/t/brand-header/77977) but I think it won’t work for me as I want to show data from API.

Hence, can anyone help me, how can I create custom theme component?

A place to start is [Beginner’s guide to developing Discourse Themes](https://meta.discourse.org/t/beginners-guide-to-developing-discourse-themes/93648) other theme guides in #Documentation .

I don’t know if it’ll help, but here’s a trivial example of accessing another site: [GitHub - literatecomputing/runners-onebox-theme: Custom oneboxes for Garmin and Strava · GitHub](https://github.com/literatecomputing/runners-onebox-theme/tree/main)
