Frequently asked questions

Ceven implements a sophisticated queuing system to stay within Chatwork API limits. Chatwork enforces strict request quotas per account to prevent abuse. When an agent triggers a large batch of requests, such as pulling messages from fifty different rooms at once, Ceven automatically paces those calls. If the API returns a rate limit error, the agent enters a backoff period and retries the request after the cooldown expires. This ensures that your integration remains stable and your account does not get temporarily flagged or blocked by the Chatwork platform during high volume data syncs.
Ceven can only access rooms that the authenticated user has permission to view. Because the integration uses the user token, the agent acts as a proxy for that specific person. If the user is a member of a private room, the agent can read and write messages there. If the user is removed from a room, the agent immediately loses access to that room's data. This permission model ensures that sensitive corporate conversations stay private and are only accessible to the people and agents authorized by the room administrator.
Yes, the agent can fully interact with the Chatwork task system. It can create new tasks, update existing ones, and mark them as complete. A common workflow is having the agent scan a chat room for phrases like I will take care of this, and then automatically creating a formal task in that room. This prevents action items from getting lost in the chat stream. The agent can also cross reference these tasks with other tools like Trello or Monday dot com to keep your project tracking synchronized across different platforms.
When the agent detects a file upload in Chatwork, it retrieves the file metadata and the download URL. It then streams that file directly to your destination, such as a Google Drive folder or an AWS S3 bucket. The agent does not store your files on its own servers long term. It acts as a secure conduit, ensuring that documents shared in a team chat are archived in your official company storage system without requiring a human to manually download and reupload every single attachment.
Ceven can manage room membership by using the member management endpoints. You can build a workflow where adding a new employee to your HR system automatically triggers the agent to add that person to the relevant Chatwork rooms for their department. The agent pulls the user ID from your directory and sends the request to Chatwork to add them to the group. This eliminates the manual process of the team lead having to remember every single room a new hire needs to join on their first day.
Chatwork API responses are paginated, and there is a limit on the number of messages returned in a single call. Ceven handles this by automatically walking the cursor. If you ask for a summary of a conversation from last month, the agent will make multiple sequential calls to fetch all the necessary message blocks. While this takes slightly longer than a single call, it ensures that the agent has the full context of the conversation before it attempts to generate a summary or extract a list of tasks.
Yes, the agent has access to the delete message tool. If a workflow is misconfigured and posts the same alert ten times, you can tell the agent to find all messages containing a specific string from the last hour and delete them. This is particularly useful for maintaining a clean chat environment when testing new automation logic. The agent identifies the message IDs first and then issues the delete commands one by one to clear the room history of the redundant or incorrect posts.
The agent operates at the user level, but it can retrieve organization and department details for every contact it finds. This allows you to build workflows that filter messages or tasks based on the department of the person who sent them. For example, you can tell the agent to only escalate messages to the finance channel if the sender belongs to the accounting department. This adds a layer of organizational intelligence to the chat automation, making it feel more like an enterprise tool and less like a simple bot.
