Hi Shu! Yes, Lucidchart does have API functionality, though directly generating complex diagrams from free-form text prompts isn't a standard feature. However, you can use the Lucidchart API to programmatically create and modify diagrams, which can be part of a larger system that processes text prompts. The Lucidchart API offers a range of capabilities that allow for programmatic interaction with diagrams. Primarily, it enables document creation and modification, giving users the ability to generate new Lucidchart documents and dynamically alter existing ones. This includes adding, modifying, and deleting shapes, lines, and text within diagrams, as well as manipulating the layouts and styles of those diagrams. Also, the API supports data import, allowing users to populate diagrams with data from external sources like CSV or JSON files. Finally, the API facilitates automation, empowering users to automate repetitive diagram creation tasks and to integrate Lucidchart with other applications, streamlining workflows and increasing efficiency. Let us know if that helps!

​@shu Thanks for your reply just now, unfortunately the screenshot you provided in your reply contained your API key, which is sensitive information to your account. We’ve taken down your original reply to protect your account’s privacy, and would suggest that you delete that api key from your account and generate a new one to avoid any unwanted access by anyone that might have seen it before we were able to take down your post.

Hi SHira, Thank you for your reply!
We understand that it is not possible to draw through the API in natural language. But are you saying that it is possible to draw through the API at the prompt of the program?

1 Does the LucidchartAP| allow programmatic (Python) generation of new Lucidchart diagrams?
I was trying to create a future timeline by referencing the Lucid Rest API Creat/Copy/Import Document, but it seems that only the file name is created and not the contents of the document. Did I do something wrong with the procedure or code? escreenshot omitted]

I’d like to clarify and correct a bit of ​@Shira M ‘s reply. Our API does not currently allow for any means of editing the contents of an existing document, but it does allow for importing and creating new documents from JSON input. So there is not a way for a program to prompt a change to an existing document via our current API, but you can definitely write a script that generates new documents.

Here in our documentation you’ll find the overview for Standard Import (our JSON import) with some explanations about how to set up files for import, how to format the JSON, etc. You’ll also find links to some open source example scripts we have built to leverage this API under this heading. Give that guide a look, then give the import endpoint another try, and if you’re still running into trouble, reach back out and we’ll be happy to assist (just make sure to redact any sensitive/authentication information )!

Thank you for your response.

I have been struggling with the above operations and am at a point of giving up.

I am trying a different approach and would appreciate your support. My goal is to create documents using data through an API. This time, I would like to create an organizational chart using data in CSV format.

When I operated through the UI, I was able to create a document like this. (Without using the API)

I would like to confirm the following:

1. Is it possible to create an organizational chart using CSV format data through the API?
2. When I tried the code below with the API, a popup appeared saying, "This document contains the extension sheet-adapter requires the installation" when I opened the created document review. Can you please advise me on how to address this?
