Hi Rakesh

Thanks for posting in Lucidchart Community! Unfortunately based on what you've described we don't support an API that completely fulfills your use case. However our list of available APIs can be accessed here if you wish to review the available resources. 

If there's specific API functionality you'd like to see added to Lucidchart in the future would you mind adding your idea to our product feedback area of the community? We are continuously looking for how we can make our product more useful and effective for our users and ideas submitted there are passed on to the product development team for their consideration.

Thanks for your request and I'm sorry for the inconvenience. 

Hi! Updating this thread with exciting news - we've recently launched Lucid for Developers a community space dedicated to supporting and connecting our users working with the Lucid API and our most technical features.

In this section the developers actually building Lucid’s APIs will be available to answer your most technical questions just like this one. Furthermore here we plan to announce new endpoints tools and guides to help you have the best possible experience developing on Lucid’s APIs. You can browse existing posts connect with other users with similar questions and goals and ask questions of your own by creating a new post or leaving a comment. Thank you and we're excited to hear from you!
