I know that I can generate a .csv file for a given chart via the File->Export->CSV of shape data, but I’d like to do this programmatically a directory at a time.Is there any sample code of how that can be done, please?

Iam trying to integrate Lucid chart to a third party service to provide an  option import process diagrams from Lucid Chart to our clients I have asp.net web application and I have setup Oauth 2.0 and am able to retrieve document list and contents using Lucid Rest API . But in order to convert the et lucid document to BPMN which is the set format of data import in our application I want to get the details of the shape libraries and graph < is there an API which can fetch me the details of shape library and its Names without using a legacy API which requires Oauth 1.0 authentication .

Hello,For my custom LucidChart extension, I am actively working on a .NET 8.X C# OAuth 2.0 client to the Lucid REST APIs.  My approach was to create a LucidChartClientBase and then LucidChartUserClient and LucidChartAccountClient that derive from it. Here is an example of what LucidChartUserClient looks like:  static async Task UserClientStuff() { var user_client = new LucidChartUserClient(clientId, clientSecret, redirectUri, userScopes); await GetAccessTokenAsync(user_client); try { var introspectionResult = await user_client.IntrospectTokenAsync(user_client.TokenData["access_token"].ToString()); Console.WriteLine($"Introspection result: {JsonConvert.SerializeObject(introspectionResult, Formatting.Indented)}"); var accountInfo = await user_client.GetAccountInfoAsync(); Console.WriteLine($"User profile: {accountInfo}"); // Fetch all documents without any filters var allDocuments = await

Is there a way Load up the “Flowchart” template. Select any shape in the template.  In the right context panel, there is a label “Change Shape” where the user can pick a different shape.Is it possible to add additional shapes in this drop down box?  I would love to be able to add a few of my shapes from my custom extension package. Possible?

I’m trying to create a custom shape that only has two link points, similar to “DC Voltage Source 1” in the “Circuit Diagrams” → “Power Sources” library.  Link points are circled in green. When I try to create a custom shape, I can add link points just fine.  There are two below in my custom shape in the corners (because I am debugging right now), and they are circled in green.  These appear when I am drawing a line.  The trouble is, there are four points that show up by default, and I can’t figure out how to get rid of them.  They behave differently from the link points above and show up whenever I hover the cursor over my custom shape.What are these four default points, and how can I modify the custom shape definition to remove them?  The “DC Voltage Source 1” shape from Lucid’s library doesn’t have them, so it must be possible.  I just can’t figure it out from the documentation. Here’s “library.manifest” for my custom shape:{ "name": "Electrical Symbols", "shapes": [ {

Hello,Is there a programmatic way of knowing when the shape selection has changed?I have a right context in my package and custom shapes.  My custom shapes have a  custom data property on it called q_type.  What I want to do is:Click open the right click context panel.  Keep it open. Select Shape1 which has a custom data property “q_type” value of “foo”.  Show the “foo” form in the right click panel.   User now selects Shape2 which has a custom data property “q_type” value of “bar”.  Show the “bar” form.In my extension app, can I register a method to a on selection changed event?Thanks, Dan

I have created a LucidChart package that has custom shapes, data connectors and extension editor.  My custom package adds custom data fields to shapes and that is working great.I need similar capability to add custom data to either the document or a page.  My gut says the feature exists and is probably staring at me in the documentation but I honestly am not seeing it.  On a similar note, if the feature exists, how can I, as a standard user in LucidChart, see or manage the custom data of the document and/or page in the UI?Thanks, Dan

I have a need to provide a Connector with custom data fields.  My intent was to add a “connector” shape to a custom shape library.  After playing with the custom shape library, I do not feel this is possible.  Is it?  assuming it is not possible, any suggestions?  Perhaps my extension package would handle whenever some creates a new connector, it detects it and adds the custom field?Thanks, Dan

I've developed an app which connects to the Lucid API and calls GET https://api.lucid.co/documents/{doc_id}/contents to retrieve the contents of a document.Most of the time, my request is successful: I get back a 200 response along with the JSON document.However sometimes the Lucid API server fails to return the document. Instead I see this error.Why is this happening? The document in question is only about 360KB, so it's not particularly large, and it is certainly not being modified by anyone.Error: {"code":"badRequest",        "message":"Bad or malformed request",        "requestId":"8964e70358ce692e",        "details":{"error":"Document 62563ead-aa4a-4d29-8f2d-858a0a163b0d is too large to retrieve contents."}} ContextThe scopes used to create the access token areconst SCOPES = ["lucidchart.document.content", "offline_access", "user.profile"];The document request isconst LUCID_API_HOST = "https://api.lucid.co";const url = `${LUCID_API_HOST}/documents/${docId}/contents`;const headers

Team,I am developing a LucidChart extension package.  It has editor extension, shape library, etc. Within my editor extension, I will be using Modal and Panel that gets its content from React.  I need the Lucid parent Modal or Panel to send data to child React app where the user will make some edits.  After editing, the child react form will send back to the parent Modal or Panel.I have followed the documentation but the end result is very inconsistent.  Sometimes the react app gets the message and sometimes it does not.  Maybe I have implemented it wrong.The package code, including the React app can be found in this public Repo:https://github.com/GreenShoesLLC/lucidchart_package_testHere are the details.When the user clicks on a shape, the test package adds a menu that when clicked, shows the following Lucid Modal. import { EditorClient, Modal, Viewport} from 'lucid-extension-sdk';export class EditorModal extends Modal { constructor(client: EditorClient) { super(client

Hi! We like to automate our onboarding and offboarding process through a given product’s API, and part of our offboarding process for a User from Lucid is:Determining if the User owned documents Transferring those documents to another suitable UserI’m having a hard time finding an endpoint in the Lucid API docs that allows me to provide a User ID to obtain the documents they own. I don’t see a practical way of doing this. I could GET the https://api.lucid.co/documents/:id endpoint with a multi-threaded “scanner” approach that increments the documentId (a UUID) every call (this would only take several trillion API calls per User) and collects documents with a matching creatorId of the target User, but I’m hoping for a more efficient approach. I could use help. What is the simplest endpoint of the Lucid API I can use to retrieve a list of a User’s owned documents? 

I've created a shape object that has three fields. One field is named "Field" this is the column name of a data source where I want to count values in the rows that match a specific value. The next field is named "Value" this is the text value I want to match and count in the column of the data source. Finally I have a third field named "Count" that has a formula that counts the rows in the data source where the name matches. This solution has worked great for the last week or so. I can duplicate the shape and change the "Field" value or the "Value" value and I get the counts I want, very reusable. I wanted to evolve this by putting my shape in a container and having the "Field" value be a formula that pulled the value of the container name/label. When I did this it seemed to work the new "Dynamic Field" pulled the value I wanted that matched the static "Field" value. But when I updated the formula to use the "Dynamic Field" value my count ended up being 0.  Screen shot of the "Count"

It seems that there is a limit of document size when trying to retrieve the content of a document with the endpoint https://api.lucid.co/documents/{YourDocumentId}/contentsThe limit is about 40000 lines in the json result.If this limit is exceeded the endpoint returns an error code of 400  for bad request which is not a good response as the endpoint is successfull when the same document contains less elements (block, lines, groups, ...)Any explanation?Best regards.

Hii Can I import a UML diagram created via some other tool (say PlantUml) in a lucid document through its api.If so then what will be its import format and will it be editable ??  

Is there a way to use the API to set the Status on a document?

Is there a way to search for documents, using the API, using tags, status and/or classification as a search parameter?

Hello, where to start to make diagrams programatically using Lucid API? I would like to access Lucis API from python program and make diagrams. Any snippets to start with? How to get access to Lucid API?

Hello all! I have been working for some months now on building and supporting a Lucid extension (mostly used in LucidSpark). Extension works great, but lately I’ve noticed an increase in the number of errors showing up in the console that do not appear to be related to my extension - but I could be wrong. I’ve attached a few of the errors and just want a high-level opinion if these are things I need to be concerned with and dig deeper into to address. The first image below shows some errors that occur upon initial load of a document. The other two just pop up here and there. None of these appear to be actually causing problems, but thought I’d check.Thanks! 

Via REST API import document it is possible to create a document with sticky notes. But it is not explained in the documentation how it is possible to add tags to the note?{ "id": "shape4", "type": "stickyNote", "boundingBox": { ... }, "style": { ... }, "text": "Text", "actions": [ ... ], "customData": [ ... ], "linkedData": [ ... ], "opacity": 100, "note": "Test Note" } Where I can add tags (tag labels) to the shape? Thanks

Is there a way to hide programmatically a shape in a diagram in an extension?

I would like to use my logo to the panel that i’m building in an extension.I have a file “mylogo.png” in the public directory of my extension project. I use this code to define the panel.class MyPanel extends Panel { private viewport = new Viewport(this.client); constructor(client: EditorClient) { super(client, { title: 'My Panel', content: 'Hello this is my panel', iconUrl: 'mylogo.png', location: PanelLocation.RightDock, }); }The mylogo icon is not displayed and it is replace by an unknown image: What i’m doing wrong?

In an editor extension, I know we can add an image to a shape using the Fill property of the style of a shape.But how could we retrieve the image of a shape?The use case is to be able to change the image according to the value of a shape date.Thanks
