Developer Q&A

I am currently using the Front sdk updateDraft function in the updateMode: ‘replace’ when I run it with only the subject defined, all attachments on the draft get deleted.  await sdk.updateDraft(draftId as Parameters<FrontSdk['updateDraft']>[0], { updateMode: 'replace', subject: subject });This is the current code I am using.

Hello, I need a way to add custom headers into a rule webhook call, in order to call internal routes that need API keys.The solution we found was to provide the API key directly into the path parameters, but that makes it so the key leak internally in our logs. Also, making the route key-less is not an option for us.

Hi everyone, nice to meet you!I have two questions regarding analytics reports:1 Metrics showing 0:When I request a report with:metric_names = ["num_messages_sent", "num_messages_received"]start_dt = datetime(2025, 8, 10, 0, 0, 0)end_dt = datetime(2026, 3, 1, 0, 0, 0)account_id = [account_id]I get:'metrics': [ {'id': 'num_messages_sent', 'type': 'number', 'value': 0}, {'id': 'num_messages_received', 'type': 'number', 'value': 0}]However, when I manually check the contacts and conversations for this account, there are messages sent in that interval. I don’t understand why the report shows 0. Here is my code if it helps:metric_names = ["num_messages_sent", "num_messages_received"]start_dt = datetime(2025, 8, 10, 0, 0, 0)end_dt = datetime(2026, 3, 1,

I am working on a project that requires I pull data from our in house database and run reports from those and send them automatically to the respective managers that requires the report. We run these reports weekly. I would like to use Parabola to run the emails through Front. Is this something anyone has had experience with and have any thoughts on how this worked or didn’t work for you?

How can I link a message or conversation to another conversation, just like I can do it from the UI using the "Link to original" button?  I know how I can link conversations, but it's not the same as when it's done via the UI. I need to do this via the API, and there simply doesn't seem to be any option to do this. When I look through the API docs and I link the conversation, then it is just added on top as an external link, but I wanted to be internally linked within the conversation around the original conversation, just like I do it from the UI.  How would I use the API to do this? 

Hi Front team 👋We have a plugin which is created using @frontapp/ui-kit, and we’ve run into a limitation regarding dark theme support.At the moment, most (if not all) component colors in the UI Kit appear to be hardcoded. Because of this, there’s no straightforward way to support a dark theme in our plugin without overriding the existing component styles.While overriding styles is technically possible, it doesn’t feel like a clean or sustainable solution, especially considering future updates to the UI Kit.We’d like to ask: Are there any plans to introduce official dark theme support in @frontapp/ui-kit? Is there (or will there be) a theming system using design tokens, CSS variables, or similar approaches? What is the recommended best practice for supporting dark mode in Front plugins today?

Hi everyoneWe’re exploring ways to integrate our cloud contact center solution with Front and wanted to see what others here have done. Specifically, we're hoping to streamline agent workflows by syncing conversations, contact data, and possibly call recordings into Front.Has anyone here integrated Front with platforms like:Genesys Cloud WebEx Contact Center Talkdesk Five9

We are really struggling with this.Our goal is to receive a list of ‘open’ conversations in our personal inbox. This includes direct messages AND a any conversation that we are subscribed to (participant of) both in Shared Inboxes and Teammates Inboxes.However there’s an inherent problem: is:open is not useful whatsoever… Because status: “archived” is global, when a user outside of our personal inbox ‘archive in my inbox’ that status is now status:archived…This means I have to search for status:archived to see basically all my conversations (thousands) and find a way to figure out which ones are actually open in my view… we’ve tried /conversations/{id}/followers to see if i’m attached to that conversation, looking at conversation events… but its just not easy. If we had open graph or something maybe that would help…Does anyone know how to deal with this ‘global’ archiving issue, I should be able to see what my Front UI shows..

We have API integration with FrontApp for many years using our live account. We need to build an application channel for internal use only that will be used to handle specific type of group messages not currently supported by FrontApp.I already setup the developer app and application feature is installed. The app is verified and the webhook is working when I create messages on FrontApp directly.I am trying to sync an external message back into the channel, but I am getting this error“Only partners can access channels. Please see https://dev.frontapp.com/docs/channels-overview for access.”I looked at the documentations and it requires the app to be developed before I can get a partner account, but I can’t develop the app if I can’t sync the messages.Again, this is for internal use only. The reason we are choosing application app instead of custom channels is custom channels can’t "Compose new outbound messages with replies threaded in the same conve

Hi allI’m looking to save emails (and attachments) from conversations in Front to my software using its API. I’ve created application requests and can send and receive data with them. I can create a new document in my software using a Front macro but the document is empty, because I don’t know what I should use in Front to save the email and attachments too.Hoping for some pointers!Thanks

We are experiencing issues with long automated messages failing to send.There are carriers that take the long messages and carriers that don’t - we want to just retry the ones that fail. I get that I can circumvent this problem by splitting the long message into multiple small messages and send them separately. But since most of the times the messages are delivered, we don’t want to have to split successful messages because of a few unsuccessful ones.After the message is sent, I am using this endpoint to fetch the message again:"https://api2.frontapp.com/messages/{message_id}”What I want is to see if it errored or not. The issue is that I am getting the field ‘Error Type’ empty even for failed messages.Anyone has any advice here? How can I get from the API the error status of a message?

We are using a front webhook for “all incoming messages” and forward these to our own endpoint. I need to filter out ONLY NEW conversations somehow but it seems quite tricky looking at the webhook payload. We only have a professional account (and wont upgrade to enterprise any time soon). How could I reliably filter out all replies and follow up emails and only keep NEW conversations when processing the webhook event?

Summary Enable creating and managing comment reactions (emoji reactions) via the Front API, similar to how reactions work in the Front UI.Current State The Front API currently supports:Creating comments on conversations Editing existing comments Listing commentsHowever, there's no endpoint to add, remove, or list reactions on comments.Requested FunctionalityPOST /comments/{comment_id}/reactions — Add a reaction to a comment DELETE /comments/{comment_id}/reactions/{reaction_id} — Remove a reaction Include reactions in the comment object when fetching commentsUse Case: AI Agents AI agents that assist support teams need lightweight ways to acknowledge information without adding noise to the conversation thread. Reactions are ideal for this:Acknowledgment signals — An

Hi,We want to detect order numbers such as PO-123456, PO123456, or PO 123456 in a conversation using an application object. What would the pattern look like? Do I need to create 3 separate application object features?Best Regards

How come we are unable to link anything and everything? I have 2 conversations linked, but I want to link a 3rd conversation with the non-original, but can’t.

Hi,We’ve started receiving 400 Bad Request errors when calling the conversations/search endpoint. A request such as:https://api2.frontapp.com/conversations/search/after:1762920938801 now returns:400 Bad Request {"_error":{"status":400,"title":"Bad request","message":"Unsupported search modifier provided."}} We aren’t using any other modifiers, and there have been no changes on our side. The issue began on 23 July 2025. From what I can see, using after: is still documented and there’s nothing in the changelog that suggests this behaviour should have changed.Do you h

Hi everyone,I'm building an automation using n8n together with the Front API, and I'm running into a major challenge regarding attachment ordering inside a Front draft. I would really appreciate deeper clarification from the community or the Front team, because this is critical for my use case.ContextI'm a service provider and we onboard customers into different training programs. Each onboarding email contains multiple PDF attachments in a fixed order.From these files: 6 documents are always the same and are already included inside a Front Message Template 3 documents are unique per customer (contract, schedule, and one additional document), and these three files are generated dynamically in n8n and added to the draft in the same step after the template content is applied Because of this setup, I rely on a Front template for the 6 standard documents, and n8n is responsible for attaching th

I am attempting to build a sidebar plugin in Retool so I can utilise all of my existing modules, components, and queries so I can surface important contextual information for my CS team.We all use Google sign in to login to our Retool apps, and we are having a few problems inside Front’s sidebar due to third party cookies.The native Retool sign in screen does not/cannot pop up the Sign in with Google page so I get the below 403 error when I click “Sign in with Google”  I have now tried to create a public Retool app, that just has a single “Sign in with Google” button on it (which is just a Retool button), which calls the following script on click: console.log("Front.o

I am setting up an integration and using the teammate groups API.I can successfully create a teammate group and fetch it by id: POST /teammate_groups returns 201 with an id like cir_xxx GET /teammate_groups/cir_xxx returns the full group object  But when I call:GET https://api2.frontapp.com/teammate_groups Authorization: Bearer <token> Accept: application/json  I always get:{ "_links": { "self": "https://api2.frontapp.com/teammate_groups" }, "_results": [] }  Same behavior if I use the company host https://company.api.frontapp.com. The same admin token is used for create, get by id, and list, and other endpoints like GET /teams work fine. Am I missing something about how GET /teammate_groups works, or is this a bug with the listin

I have a tool that POST a draft, with a body formatted in HTML like:“<p>Based on the information provided, we are pleased to offer you a quote of:</p><ul><li>Transport: EUR <strong>200</strong> (Excl. VAT)</li><li>Insurance (optional, on declared value) : EUR <strong>20</strong> (Excl. VAT)</li></ul>”When I visualize the draft created in Front (app or web browser), I see a blank line before the list:When I inspect the object, I see a <br></br> balise, which was not in the original HTML.This disappears when I’m viewing the draft as another person (viewer mode).And so when I send it, the blank line remains.. This is quite problematic as it gives something weird visually.

Hello Front Community,We have multiple conference rooms in our office, but currently, we don’t have any UI that shows whether a room is occupied or free.When creating a calendar invite in Front, we can add a meeting room. I’m planning to build a simple app that displays all meetings for a particular meeting room for the week.I was wondering if there is an API that allows me to retrieve the list of all meetings for a specific meeting room.Any guidance or examples would be greatly appreciated!

We Are trying to implement a Plugin using the Google Sign Button. The problem is however that the sign does not work because Google is trying to open a new window. That of course doesn't work in the plug-in within the Front app.  Hence, my question is if anyone else has built such an integration and how did they manage to integrate Google sign in within the Front app plugin?

Hey folks, I’m build a front plugin with Auth from Clerk, and running into a bunch of issues. The login screen successfully opens + launches a google oAuth login, but then fails due to clerk issues.I’m assuming it has something to do with all network requests causing a 401 when sent from the sidebar UI. Running locally/on prod we’re able to login successfully. Would love a running example in the docs for Clerk apps.

We have recently created some integrations with Front for our company. One of the things we would like to be able to do is see a report that gives us the number of API requests that we have made over a given time period with the option to break it down by API token. This would give us the ability to quickly track down changes in usage over a period of time if we were to start running into rate limiting.Is this something that exists?
