Hi Mohamed thank you for posting in the community!
As a first step would you mind checking out our Developer Portal particularly the section dedicated to document access / embedding and let me know if this is the functionality you are looking for? If not our editor's publishing / embedding function might be the tool for you.
Additionally it looks like you might be using an outdated link to access these docs -- would you mind submitting a support ticket with a screenshot of what you are seeing so we may better assist with this specific issue?
If anyone else is having API or publishing issues please feel free to contribute to this thread!
