No or very slow API replies from REST API

I am the developer of an application where we want to show pages from Lucidchart documents into our application. I want to show them by exporting each page as a jpeg file into our application. I created an OAuth 2.0 client and I can get and update a token without a problem. My application is written in PHP. To add the pages our users first search for Lucid chart documents. I use the Search document endpoint for that (https://api.lucid.co/documents/search). I then display the search results where the user can pick a Lucidchart document.Then, I use the Document Contents endpoint (https://api.lucid.co/documents/:id/contents) to retrieve what pages are in the document. I then loop over these pages to export each page to a jpg image with the Export Document endpoint (https://api.lucid.co/documents/:id?pageId=xxx).The problems I have, is that many times, the API simply doesn’t answer and times out. I almost never get an error message back from the API. I do sometimes I get a curl error 0 wit

Error when refreshing token

We are getting intermittent errors when refreshing Oauth2 tokens in our Rest API integration. We are using a legacy token (Admin > App Integration > General >App Integrations > Custom OAuth apps) and the app has been working in our test environment for months. We recently deployed to production and more users are using it more regularly. The same user will get a refresh token error one moment and then when they try again it errors (see below).We did have a scheduled process that was retrieving all documents from each user and therefore hitting the API more frequently (once per user every 15 minutes),  we have stopped that process  temporarily to see if that helps, but would like to know if there are any other known issues which would be causing the intermittent issues. {"type":"http.ClientResponse","code":400,"headers":{"Alt-Svc":"h3=\":443\"; ma=93600","alt-svc":"h3=\":443\"; ma=93600","connection":"close","Connection":"close","Content-Length":"166","content-length":"166",

Can I set document properties when importing a document?

I use the Import Document endpoint (POST https://api.lucid.co/documents) to create Lucidchart documents. I found no option to set document properties like the page size (I wanto to set that to A3) and the orientation (I want to set that to landscape).Is that even possible?

How to create a document with data in it based on a template?

Hi, I'm looking for a way to create a Lucidchart document based on a template and add my own data to it. I managed to create a document based on a template with the POST https://api.lucid.co/documents endpoint. I cannot add my own data however, as this doesn't seem to be supported by that endpoint.Another route could be to use the Import documents endpoint but then I cannot seem to specify the template to be used.Or am I missing something here?

Standard Import - control text padding and shadows

Is there a way to configure the text padding and shape shadows? I don’t see it in the documentation. Re the text padding - my use case is attempting to align some text to a shape in a legendI have to manually update the padding after the import to get it to align to the centre in the editor I’ve tried:<p style=";font-size:8pt;margin:0px">and<p style=";font-size:8pt;padding:0px">neither work Re the shadows - that would enable my items to stand out better over a plan  Thanks,

FIELDLOOKUP and LOOKUP Formulas do NOT update after data updates

While using the FIELDLOOKUP and LOOKUP functions in my document I noticed that they did not update as the associated dataset was updated. Steps to reproduce: Create a new dataset with some minimal data Create a field (variable) on the page Use the FIELDLOOKUP or LOOKUP formula in the value of that field Verify the value matches the originally uploaded data Open the data panel and make a manual edit to the data in that dataset The value of the field does NOT change (it still reflects the value that was originally uploaded) - this seems to be a bug as it is not the expected/intuitive behavior From the data panel choose to Replace the dataset with a new set of values Verify the value of the field now reflects the newly replaced value in the dataset

This OAuth2 client is not available

My team developed a web application that uses a REST API to create and then embed the Lucid Chart documents into our website.We successfully tested the integration between our app and the Lucid. It works fine as long as the user is added to the collaborators in the developers panel.However, when other users test our application they get an error saying:“This OAuth2 client is not available”The account administrator installed our application package for the whole account, but the error still persists.We don’t use the Extension API and our application is totally external to the Lucid. We just need to use the REST API only.

Extension APIs for blocks containers

Hello,I have a use case in LucidCharts where I need to identify if a block area is contained in another.In the documentation you can find this method getContainers() but it returns empty array for nested blocks. Those blocks seem to have valid bounding box values as well.Is there a correct way to use that API?

Json Response

Currently we are using LucidChart for drawing fencing diagrams. We had some questions about the Json response that we get for Get Document contents. There is some data that raised a question for us. Our overall fencing diagram through lucid allows us to drop and drag gates and overall measurements for these fences and those are pulled in through the api. Some of the gates are showing up as ERRORS! within the Json response. Also the Lines class within our json response seems to be connected to these ERROR!. We were wondering if you can provide some insight on this, I will provide an example snippet of a Json response for a better understanding.    Json:  {    "id": "f48e1227-c6df-4f9b-ad00-20a81c271d26",    "title": "SITE-000000015",    "product": "lucidchart",    "pages": [        {            "id": "0_0",            "title": "Page 1",            "index": 0,            "items": {                "shapes": [                    {                        "id": "igj.W1Apzw4F",

Document content: edges are missing labels

I have created a diagram using Decision shapes with Yes and No lines. I am using the Developer API to retrieve the document content using GET https://api.lucid.co/documents/:id/contents The shapes have Text labels which are included in the retrieved content.However, as far as I can tell, the line labels are missing in the retrieved content. I am unable to tell which lines correspond to Yes or No connections. Am I missing something here? Is there some other way to disambiguate the connecting lines?

Embed a document with Links

We have a react application and we are embedding lucid chart documents there. It works find until we click on other links. Imagine, I have a link within lucid chart to a different document. Once, I click on that link my expected behavior is to open that link within the iFrame but instead of that the link opens in the parent window. How can I control this behavior and open links within the iFrame ?

Comma in Text impacts the CONTAINED function in custom field

I’m using the REST API to export document contents to JSON.https://developer.lucid.co/rest-api/v1/#get-document-contentsIn my use case, I want to find the stick notes that belong to the container. For that purpose I’m using a custom field and the CONTAINED function.The JSON looks as follows: { "id": "vaXcl.RlvRIQ", "class": "SparkContainerBlock", "textAreas": [ { "label": "Text", "text": "People" } ], "customData": [ { "key": "Contained", "value": "[Not trained enough, Working overtime]" } ], "linkedData": []}If we change the sticky note text "Working overtime" to "Working overtime, exhausted and frustrated" then the JSON will look as follows. { "id": "vaXcl.RlvRIQ", "class": "SparkContainerBlock", "textAreas": [ { "label": "Text", "text": "People" } ], "customData": [ { "key": "Contained", "value": "[Not trained enough, Working overtime, exhausted and frustrated]" } ], "linkedData": []}As you can see the com

Using ElementProxy to get data fields for selected Jira card

Hello Lucid Devs and community.  I'm trying to get access to the data fields attached to a LucidSpark Card that was created using your Jira data connector/integration. I spoke with you all recently and you had suggested I leverage ElementProxy, but I’m having trouble getting it to work. Would greatly appreciate any help about where I’m going wrong. If you have any example code for this scenario that would be helpful as well. My 'extension.ts' file (stripped down to focus on just getting data fields):import { EditorClient, Menu, MenuType, Viewport, CardBlockProxy, DataProxy, ElementProxy, CollectionProxy,} from "lucid-extension-sdk";const client = new EditorClient();const menu = new Menu(client);const viewport = new Viewport(client);const data = new DataProxy(client);async function listDataFieldsForSelectedElement(elementId: string) { const elementProxy = new ElementProxy(elementId, client); let fieldsSet = new Set(); for (const referenceKey of elementProxy.referenceKeys.valu

Error when using 'patchItems' to update field value

Hello all! I’m posting this as a new topic, although I believe it is related to Using ElementProxy to get data fields for selected Jira card. When I try to update a field value using ‘patchItems’ on the CollectionProxy I am getting an error message saying it “could not find collection...” I set up a simple demonstration in the code below for your review, with a hard-coded update value in string format. I picked a field called “summary” which is just a string to hopefully rule out type compatibility issues. Thanks again for all of your help!Here’s my function getFieldValueFromElement, and you can see that all of the read the fields from the collection (and display the collection itself) up until I execute the patch command.export async function getFieldValueFromElement( client: EditorClient, elementId: string, fieldName: string) { // Obtain an ElementProxy for the given elementId const elementProxy = new ElementProxy(elementId, client); // Check if elementProxy is null or undefine

Document Sharing via API

Hello,  I had a couple of concerns regarding the creation of documents via the API. Currently we are creating documents into the default folder but are having issues with users viewing them. Currently only Admins have the ability to view them. Regarding this we are wondering if there is a way to share documents that are created to organizational group? Are there other ways we could share the documents to users as well?
