I can tell you that Webflow has been actively improving and expanding its API capabilities over time. They have been responsive to user feedback and have released updates and new features based on user needs. It's highly likely that Webflow will continue to enhance their API to provide more functionality and flexibility for developers and integrations.
To stay up to date with the latest news and updates regarding Webflow's API, I recommend checking their official documentation, blog, community forums, or subscribing to their newsletter for announcements. Additionally, you can reach out to the Webflow support team directly to inquire about their product roadmap or specific feature requests, as they may provide more accurate and current information on upcoming API features.
