🚀 Announcing New API Keys available on Lucid’s API!

Hey Lucid Devs! 👋 We’re excited to introduce a new way to securely access the Lucid API using API Keys ! 🔑 Even seasoned engineers sometimes find OAuth2 complex and time-consuming—it can take hours to set up properly. With API Keys, the process is far more straightforward . Simply generate an API Key in the Dev Portal and include it in your API requests! 🛠 How to Get Started Check out our API Keys Guide ! 🔒 Are there Admin Controls? Yes, Admins can choose to enable/disable API Keys . Apps with API Keys will only be accessible from the Developer Portal by the App creator and any Lucid Developer added as a collaborator to the app. See our App Collaborator roles guide for more information. 🚨 Important Notes Treat your API Keys like passwords. Do not expose them in your client-side code or share them publicly. Regularly review and rotate your API Keys to maintain security. Generally, an API Key can be used in place of an OAuth 2.0 User token, however certain endpoints– such as the Doc

Calculate the estimate of all shapes with a specific background color

Anyone know if there is a formula to calculate the Estimate value of all shapes where the background fill color is a specific Hex value? I’m still learning but here is what I have figured out so far... I have a container with 2 shapes inside it with different fill colors. I can calculate the number of shapes with a specific fill color using this formula =COUNTIF(children(page), x => FILLCOLOR(x)= HEXCOLOR('#e6e6ff')) Result of the above above is 1 since I have 1 shape that matches that hex value. And I can calculate the Estimate field using this formula: =CONTAINED."Estimate" The answer above is 5 (3 from one shape, and 2 from the other shape) But I want some way to calculate the estimate field of ONLY the shapes that have a fill color of “#e6e6ff”

Export of CSV Shape Data - Inconsistent

Hello Lucid Community, I have been leveraging the ability to export csv shape data from Lucid for the past several months; however, recently I’ve noticed that the shape names data are now coming back inconsistently. I wanted to learn if anyone else is experiencing this and/or if there is a way I can address the issue myself. This does appear to be a regression in Lucid’s export csv shape data from what I’ve experienced. I can use the exact same shape and then export the csv and the shape name will come back as a [custom title I created], but then other shapes that are of the exact same type will show a default name that Lucid provides the shape and is not using the [custom title I created] when naming the shape. Two reasons I think this is a regression, One- I have examples of a csv export of shape data for the same Lucid document that was exported months ago and if I attempt to run the same export of shape data today for the same file, the names of the shapes are no longer the same as

Script that allows bulk conversion of draw.io diagrams into LucidChart diagrams

I'm trying to create a Python script that will download the drawio files in XML or drawio formats from a list of spaces that contain pages containing drawio macros and automatically upload them to LucidChart via its API. Once the files are converted, they will automatically have new IDs generated by Lucidchart that we will use in a mapping table that will be useful later. This mapping file is really important to know where to replace the old macros by the new ones. We will need the following columns: Space Key, Page Title, Page ID, Drawio file name. We will have to use this CSV mapping file, completed with the IDs of the new Lucidchart documents, to replace the old drawio macros with the new Lucidchart macros. (This is done using HTML tags.) This way, the new pages will be updated with the new Lucidchart files. I’m still struggling to get this mapping file from my script. Anyone could help me on this?

shared link not opening in iframe

We retrieve a sharable link from the API: https://api.lucid.co/documents/document_id/shares/shareLinks which provides a shared link like: https://lucid.app/lucidchart/document/edit?invitationId=inv_id However, when trying to embed this link in an <iframe> within our application, it does not load due to restrictions. Question: How can we embed this URL within our own application without opening it in a new browser tab?

Best Resources for Learning Machine Learning for Lucid AI Projects?

Hey everyone, I’ve been exploring Lucid’s tools and looking for ways to enhance my workflows with AI-driven automation. Since AI and Machine Learning Tutorial content is everywhere, I’m wondering what the best resources are for someone who wants to apply machine learning concepts within Lucid’s ecosystem. Here are a few things I’m specifically curious about: Best beginner-friendly tutorials – Any recommendations for learning machine learning concepts with practical examples? Integrating AI with Lucid tools – Has anyone used ML models to automate or enhance workflows within Lucid? Data visualization & AI insights – Are there ways to combine machine learning with Lucid’s visualization tools for better decision-making? Low-code/no-code AI – What are some good platforms or tutorials for applying machine learning without extensive coding? If anyone has experience integrating ML into their Lucid projects or knows of great learning resources, I’d love to hear your recommendations! Looking for

Data Connector: Poll vs regular action

I am using Data Connectors. I have a Poll action as well as a traditional action (ImportSimDataAction) that is tied to a UI button that my extension editor calls performDataAction on. Both the pollAction and ImportSimDataAction call the same shared code that reads CSV files from an Azure Container and imports the csv data into a Lucid “data source” with multiple collections. For some reason, only the ImportSimDataAction use of the shared code results in the data being imported into Lucid’s data source and collections. The pollAction version runs and executes without errors, but, the data is not in the collection. Specifically, in the document's datatools, I do not see it. Only the version that starts with a user clicking on a button and calling performDataAction with ImportSimData always works. Are there known capability differences between what can be done in "Poll" vs a regular action? Thanks, Dan

Counting shapes inside a container from outside the container

Hello, Somewhat new user here. Been using lucid for a while but just getting into formula’s. I have a container with 2 shapes in it. I’m trying to get a count of the number of shapes within the container from a label that is placed outside the container. The container has a shape id of “MyTeam”. I can put a title on the container with the formula =COUNT(CONTAINED) and it works and displays 2 as the count. When I attempt to do this outside the container is where I run into problems. I’ve tried the following…. =COUNT(#”MyTeam”.CONTAINED) This results in an error saying "CONTAINED" was not found in "PCL5j ikY4cLF" If I just reference =#”MyTeam” from my label it displays the containers name so the reference seems to work. I tried to wrap it in a container object like below… =COUNT(CONTAINER(#”MyTeam”).CONTAINED) This does not error however the count displays as 0 on the label. Thanks in advance for any help!

Custom Shapes - JSON

Hi, I’m using JSON to create Custom Shape. I have two questions to go further : 1 . Is it possible to identify to which shape a line is connected when using a Custom Shape? For example, using the formula (=DOWNSTREAM), I can see all the shapes in my Custom Shape. However, I don’t know how to identify the element directly connected to my line. Is it possible to take a value from the parent document and use it in a Custom Shape? When I try to use a formula in a Custom Shape, it is processed as a string. I have tried various ways to makes it work, like the example below. Thanks for your help, NM

Is it possible to import cards without a data connector?

As the title already mentions, I’m working on a POC following the instructions from this walk through: https://developer.lucid.co/docs/lucid-card-integrations But when it comes to the point of actually importing the cards, the articles creates a separate dataconnector to perform the import. More specifically in this part of the walk through: https://developer.lucid.co/docs/lucid-card-integrations#call-the-import-action Is it possible to implement the import function to just make an http call from the editorextension? Or it is a requirement to use a connector in between? If so, are there any examples available? Thanks.

Programmatically create shapes and lines using REST API?

Hello Lucidchart Developer Community, I'm currently exploring the functionalities of the Lucidchart API and I've hit a roadblock. My project requires dynamic creation and manipulation of diagram elements, specifically shapes and lines, and I'm curious about the extent of Lucidchart's API capabilities in this regard. Does Lucidchart offer a REST API that allows for the programmatic creation of shapes and lines within a diagram? I'm interested in understanding how detailed this control is, such as specifying types, sizes, positions, and custom styling for these elements. Additionally, how feasible is it to dynamically add, modify, or interconnect these elements within a Lucidchart document via automated processes or external applications? Any insights, documentation references, or examples of similar implementations would be greatly appreciated. Looking forward to your responses and guidance! Best regards, Nikolai

Difficulties of using the import API to create new diagrams

Hi, I am trying to create new diagrams using the import API but I am facing lots of issues: If I take an existing diagram that I want to use as a template, the format for the import is different I can't use the same shapes that in my original diagram (e.g. AWS shapes) in a JSON file that I want to use to import This is quite blocking honestly. Why can't we create diagrams similar to existing ones created from the editor?

Dynamic properties names

Hi, Is it possible to concatenate strings to call a propertie.

Latest Version of Mermaid in Lucidchart

Can the latest version of mermaid be supported in Lucidchart? With the current supported version, I am getting a few syntax error while testing out the default syntax from mermaid website. Once the flowcharts have been created using the code, can we have the following features? Conditional formatting to update the block, line (arrow) and text color, size, font style. Provide an option to copy the generated flow into a new image so that conditional formatting can be applied as needed.

Do I have access to API with a free trial?

I have signed up for a 7-day Free Trial of the ‘Teams’ level of subscription and want to create some templates in bulk via the API before my company sorts out it licensing. I have followed some guides and managed to create an API Key, but it is not working when I try to test it via Google Colab. I’ve tried it several times now and wonder if it is just not going to work while I’m on the ‘Free’ trial status?

What is the difference in icons

When I add an item to a collection from a data connector vs extension editor, it appears different in the Data Tools UI. model_definitions were created in the extension editor and does not have a paper icon next to it. The other collections were created in my data connector and they have a paper icon next to them. What does the paper icon mean? Perhaps on a related note, but, when I add an model_definitions item with the exact same primary key, I am getting duplicates of that item. Despite my best efforts (so far), I am unable to “update” an existing collection item when using the extension editor. Items added to collections from my data connector do not create duplicates. Thanks, Dan
