Hello everyone!
As we transition to our public beta release of App Components (previously called Platform UI), we have made several changes to our API interface to conform to the standards of our REST API. These changes mostly include modified request and response formats for our endpoints. We have compiled a list of changes here detailing each change with context/reasoning and example requests/responses.
We will continue supporting the current behavior of the App Components API until October 1st 2021. After then we will only support the new behavior listed in the attached doc.
Thank you so much for your support and don’t hesitate to let us know if you have questions! You can reach out to us through the usual communication channels or by leaving comments on the attached doc summarizing the API changes.
